安化县2008年节水灌溉工程可行性研究报告.doc

increase rice harvests without expanding the area of the fields. in 1950, chinese farmers could produce only fifty million tons of rice. in a recent harvest, however, nearly two hundred million tons of rice was produced. these increased harvests mean that 22% of thwart worlds people are fed from just 7% of the farmland in china. dr yuan is now circulating his knowledge in india, vietnam and many other less developed countries to increase their rice harvests. thanks to his research, farmers are producing harvests twice as large as before.dr yuan is quite satisfied with his life. however, he doesnt care about being famous. he feels it gives him less freedom to do his research. he would rather keep time for his hobbies. he enjoys listening to volin music, playing mah-jong, swimming and reading. spending money on himself or leading a comfortable life also means very little to him. indeed, he believes that a person with to much money has more rather than fewer troubls. he therefore gives millions of yuan to equip others for their research in agriculture.just dreaming for things, however, costs nothing. long ago dr yuan had a dream about rice plants as tall as sorghum. each ear of rice was as big as an ear of corn and each grain of rice was as huge as a peanut. dr yuan awoke from his dream with the hope of producing a kind of rice that could feed more people. now, many years later, dr yuan has another dream: to export his rice so that it can be grown around the glboe. one dream is not always enough, especially for a person who loves and cares for his people.chemical or organic farming?over the past half century, using chemical fertilizers has vecome very common in farming. many farmers welcomed them as great way to stop crop disease and increase production. recently, however, scientists have been finding that long-term use of these fertilizers can cause damage to the land and, even more dangerous, to peoples health.what are some of the problems caused by chemical fertilizers? first, they damage the land by killing the helpful bacteria and pests as well as the harmful ones. chemicals also stay in the ground and underground water for a lonog time. this affects crops and, therefore, animals and humans, since chemicals get inside the crops and cannot just be washed off. these chemicals in the food supply build up in peoples bodies over time. many of these chemicals can lead to cancer or other illnesses. in addition, fruit, vegetables and other food grown with chemical fertilizers usually grow too fast to be full of much nutrition. they may look beautiful, but inside there is usually more water than vitamins and minerals.with these discoveries, some farmers and many customers are beginning to turn to organic farming. organic farming is simply farming without using any chemicals. they focus on keeping their soil rich and free of disease. a healthy soil reduces disease and helps crops grow strong and healthy. organic farmers, therefore, often prefer using natural waste from animals as fertilizer. they feel that this makes the soil in their fields richer in minerals and so more fertile. this also keeps the air, soil, water and crops free from chemicals.organic farmers also use many other methods to keep the soil fertile. they often change the knd of crop in each field every few years, for example, growing corn or wheat and then the next year peas or soybeans. crops such as peas or soybeans put important minerals back into the soil, making it ready for crops such as wheat or corn that need rich and fertile soil. organic farmers also plant crops to use different levels of soil, for example, planting peanuts that use the grounds surface followed by vegetables that put down deep roots. some organic farmers prefer planting grass between crops to prevent wind or water from carrying away the soil, and then leaving it in the ground to become a natural fertilizer for the next years crop. these many different organic farming methods have the same goal: to grow good food and avoid damaging the environment or peoples health.an early farmer pioneersome people thought jia sixie was a lucky man. he had worked for the emperor and when he got old, he was able to go his hometown to relax. jia sixie, however, had other plans. he had always been interested in agriculture and intended to do something to make chinese farming even better.jia sixie lived in the six century ad. he was born in yidu in shandong province and worked in gaoyang, which is also in shangdong. as he rode through the countryside on his journeys for his work he looked out at the fields. some of them were greener and had more crops than others. some cows and sheep looked healthier than others too. he was lost in though. what could a farmer do to get good crops from his fields? surely there must be rules that would help them. he thought he could use his knowledge to find out the best ways for farmers to grow crops and then write a book to help them. in doing so he collected information from farmers who did well, studied it and did experiments to find the best way.for example, he studied ways of keeping seeds and advised farmers to choose seed-heads which had the best color. then he told them to hang them to dry all winter. the next spring the seeds should be knocked out of their seed-heads and planted. he studied how to improve the soil. he advised farmers to clear weeds from the ground before planting crops. they could either let the animals eat the weeds or turn the soil over so that the weeds were covered and would rot. then he gave advice on turing over the soil. the first time each year, farmers should dig deeply, but the second time should be less deep. therefore the autumn ploughing of the soil should be deeper thant the spring ploughing. he suggested changing crops in the field every year: rive one year and wheat the next so that they would always get good harvests. they should also grow different plants next to each other in the field. he also gave adive on how to fish, keep a garden and even make wine.he wrote down his in a book called qi min yao shu, which was considered an important summary of the knowledge of farming. for centuries after jia sixie died, it was studied by chinese farmers and students of agriculture.unit 3a master of nonverbal humouras victor hugo once said, “laughter is the sun that drives winter from the human face”, and up to now nobody has been able to do this better than charlie chaplin. he brightened the lives of americans and british through two world wars and the hard years in between. he made people laugh at a time when they felt depressed, so they could feel more content with their lives.not that charlies own life was easy! he was born in a poor family in 1889. his parents were both poor music hall performers. you may find it astonishing that charlie was taught to sing as soon as he could speak and dance as soon as he could walk. such training was common in acting families at that time, especially when the family income was often uncertain. unfortunately his father died, leaving the family even worse off, so charlie spent his childhood looking after his sick mother and his brother. by his teens, charlie had, through his humour, become one of the most popular child actors in england. he could mime and act the fool doing ordinary everyday tasks. no one was ever bored watching him-his subtle acting made everything entertaining.as time went by, he began making films. he grew more and more popular as his charming character, the little tramp, became known throughout the world. the tramp, a poor, homeless man with a moustache, wore large trousers, worn-out shoes and a small round black hat. he walked around stiffly carrying a walking stick. this character was a social failure but was loved for his optimism and determination to overcome all difficulties. he was the underdog who was kind even when others were unkind to him.how did the little tramp make a sad situation entertaining? here is an example from one of his most famous films, the gold rush. it is the mid-nineteenth century and gold has just been discovered in california. like so many others, the little tramp and his friend have rushed there in search of gold, but without success. instead they are hiding in a small hut on the edge of a mountain during a snowstorm with nothing to eat. they are so hungry that they try boiling a pair of leather shoes for their dinner. charlie first picks out the laces and eats them as if they were spaghetti. then he cuts off the leather top of the shoes as if it were the finest steak. finally he tries cutting and chewing the bottom of the shoe. he eats each mouthful with great enjoyment. the acting is so convincing that it makes you believe that it is one of the best meals he has ever tasted!charlie chaplin wrote, directed and produced the films the starred in. in 1972 he was given a special oscar for his outstanding work in films. he lived in england and the usa but spend his last years in switzerland, where he was buried in 1977. he is loved and remembered as a great actor who could inspire people with great confidence.an april fools joke: the noodle harvestapril fools day, or april 1st, is known in many countries as a day for playing jokes on others. it is usually a time when children make fun of each other, but sometimes other people can get caught in the fun too.one of the most famous jokes in england took place on british television in 1957. it was a monday night when there were always many serious programmes on the television. one of them was called panorama, this show explored problems and progress all over the world, so nobody was surprised when it安化县2008节水灌溉工程可行性研究报告一

项目建设的必要性和可行性2.1 项目建设的必要性廖家坪灌区是安化县的主要粮食生产基地,以种植双季水稻为主，农田需水量多，因此灌溉系统在农业生产中占有十分重要的位置，不但是农业的命脉，而且是国民经济的基础产业。为了促进灌区的经济发展，增加农民收入，在灌区进行末级渠系工程的修复、续修、新建和改造是十分必要的。1）实施项目建设是加快农业产业结构调整，实现农业现代化的迫切需要。随着我国全面建设小康社会，对农业生产提出了更高的要求，种植业结构调整已经成为农业高产稳产的重要途径。项目区粮食作物以水稻为主，效益不高，实施项目区末级渠系建设，可以发展大豆、油料等高效农业、精品农业。同时，加大项目区末级渠系节水工程改造，改善水系条件，也为加快现代化进程奠定了坚实基础。2）实施项目建设。是实现节水增效，提高农业生产水平的迫切需要。随着工农业生产的发展和人口的增长，水资源的供需矛盾日趋紧张，水资源紧缺将成为21世纪全球性的课题。随着水价改革的推行，供水成本将有较大幅度的提高，灌区现行的粗放式农业灌溉方式急需向集约化、精细化灌溉发展。通过项目区末级渠系节水改造，能有效解决水资源供需矛盾，提高灌溉保证率，降低农业成本，努力提高农业生产水平和投入产出率。3）实施项目建设是强化水利行业管理，实现水利产业化发展的迫切需要。随着农村经济体制改革的深入发展和社会主义市场经济体制的逐步完善，小型农田水利工程建设和管理中一些深层次的矛盾显露出来，由于投入不足，工程配套陈旧，设施老化，效益衰减，农业生产喝“大锅水”的现象依然存在，直接影响到农业的持续发展。实施项目区末级渠系配套建设，提高灌溉工程保证率，可加强水利行业管理，实施小型水利工程产权制度改革，建立良性运行机制，以促进小型水利工程的可持续发展。4）实施项目建设是改善项目区工农业生产条件，提高农民生产生活质量的内在要求。由于项目建设受当时投资的制约，设计标准低，末级渠系配套改造衬砌率低，严重制约了项目区内工农业生产的发展。在中央加大农业投入，加快农业产业结构调整，实现农业现代化的今天，通过项目区末级渠系节水改造，可以改善工农业生产环境，保障农民安居乐业，有利于社会安定团结。5）实现项目建设是实现水资源优化配置和高效利用的需要。项目区工程建设已具备一定的条件，并渐趋完善，目前面临的问题是如何进一步发挥工程系统的效率，以实现项目区水资源优化配置和高效利用并适应市场经济的需要。6）实施项目建设是保障水土资源合理开发利用与保护，实现生态环境与社会经济协调发展的需要。综上所述，安化县小型农田水利工程建设是十分必要的。也是十分迫切的。22项目建设的可行性 1）安化县委、县政府十分重视小型农田水利工程的建设。成立了小型农田水利工程建设项目领导小组，协调项目的组织实施工作。2）项目区具有良好的自然条件、灌溉条件。由于主干渠工程已基本完成衬砌，上游库区集雨面积大，水资源丰富，所以在水资源供给上有了良好的保障。3）项目区具有较强的协同能力。项目区经济有一定的基础，配套资金能够得到保障。各级政府、各行各业为实施灌区末级渠系改造已做好了思想上、经济上和技术上的准备。4）廖家坪灌区管理处对建设高度重视，对各分项目积极进行技术上的指导和支持。5）各项目区用水户协会已初步成立。通过项目建设，可以提高渠系的利用率，改善渠道过流条件，保证工程正常运行，减少田间用水损失，进而恢复和扩大灌区的灌溉面积，促进农业产业结构调整，不仅十分必要，而且技术上是可行的。另外，健全的组织机构和中央及地方补助资金的落实到位为项目顺利实施提供了有力保障。项目区建设具有良好的经济效益、社会效益和生态效益。因此该项目不仅是必要的，而且在经济和技术上也是可行的。三、建设条件分析（一）、项目区自然概况项目区位于廖家坪灌区，属亚热带季风湿润气候区，气候温暖湿润，土地肥沃，光热丰富，雨量丰沛，宜种面积广。灌区农田地面高程一般在260-180m之间,地理位置东经1111411121,多年平均气温16.6,七月最高平均气温29.0,极端最高气温43.6,极端最低气温-13.2，多年平均降水量在1491.9mm，降水日数156.3天，多年平均蒸发量1225mm，多年平均风速2.4m/s。多年平均日照时数1602.4小时，多年平均降雪日数12天，无霜期为253天。项目区地面植被良好，林木品种丰富，森林覆盖率为723%，自然资源木材、楠竹、煤等产量丰富。区内土壤大部分为粘土、黄壤土等，有机质含量高，适宜于农作物生长。（二）、项目区社会经济状况项目区现有人口6384人。耕地面积8466亩。2007年工农业总产值为3820万元，其中农业总产值1690万元，工业总产值2130万元，农民人均纯收入1800元，项目区主要粮食作物是水稻，2007年粮食总产量6584吨，主要经济作物有茶叶、烤烟、花生和中药材等。从项目区的自然概况和社会经济来看，具备建设的基本条件。（三）、项目区基础设施项目区已建水利骨干工程包括山平塘 152口，河坝46处，灌溉渠系85.98km 。但由于绝大部分灌溉设施兴建于六十年代，受当时条件制约，工程设计标准低，施工土法上马，盲目追求进度，忽视工程质量，标准低、质量差，运行几十年来，工程已严重老化。特别是现有灌溉支渠绝大部份为土渠，冲刷、淤积、渗漏严重，加上年久失修，渠系利用系数仅达0.3，严重影响了效益的发挥。近几年通乡通村公路的建设，加速了农村交通的快速发展，项目区内交通便利，施工方便。水、电、通讯设施等都已进入村组（四）、项目区改造项目的水源、供水保证率等条件项目区计划改造的项目包括支渠防渗改造4条10 .4km,斗渠新建15条19km ,农渠新建23条17.4km，山塘新建1口0.6万方。由于项目区工程的水源主要来自廖家坪水库，库区降雨丰沛，集雨面积大，达142.8km2，库容达4280万方，故改造项目的水源丰富，供水保证率可达 90%以上。四、项目建设内容及技术方案4.1、项目实施地点、范围和实施计划根据农户自愿及因地制宜的方针，项目区实施地点和范围包括：清塘项目区的木桥村，由灌区内的木桥支渠灌溉，支渠设计流量0.0594m3/s，山溪村，由山溪支渠灌溉，支渠设计流量0.0418m3/s，三里冲村，由田湾支渠灌溉，支渠设计流量0.0773m3/s，梅城镇的中田村，由左干渠的田心左支渠灌溉，支渠设计流量0.2517m3/s，夏桥村，由田心左支渠灌溉，支渠设计流量0.2517m3/s，仙溪镇的雷公山村，由右干渠的伏堂支渠灌溉，支渠设计流量0.2409m3/s，长塘镇的杨台村，由右干渠的通溪支渠灌溉，支渠设计流量0.2734m3/s，柳溪村，由右干渠的通溪支渠灌溉，支渠设计流量0.2734m3/s，乐安镇乐兴村，由左干渠的乐安右支渠灌溉，支渠设计流量0.1624m3/s，受益范围：清塘镇的三里村320亩、木桥村435亩、山溪村380亩，田湾支渠840亩（不含项目村），木桥支渠670亩（不含项目村），梅城镇中田村340亩、夏桥村410亩，田心左支渠1040亩（不含项目村），仙溪镇雷公山村360亩，伏堂支渠950亩（不含项目村）。长塘镇扬台村405亩、柳溪村450亩，乐安镇乐兴村400亩，合计7000亩。实施计划：项目建设期从2008年8月至2008年12月，具体安排如下：2008年8月9月：主要完成项目区前期准备工作；2008年10月2008年12月：工程的施工与建设；2009年1月：对项目区的各项工程进行初步验收。4.2、建设内容和技术方案4.2.1建设内容清塘铺镇项目区：田湾支渠防渗改造1条1.8km，三里冲斗、农渠新建5条3.7km，山溪村斗、农渠新建4条3km，木桥支渠防渗改造1条3.8km，木桥村斗、农渠新建5条3.2km，木桥村山塘新建1口0.6万方，配套农渠1.5km。梅城镇项目区: 田心左支渠防渗改造1条2.4km，夏桥村斗、农渠新建5条4.4km，中田村斗、农渠新建4条4km。仙溪镇项目区: 伏堂左支渠防渗改造1条2.4km，雷公山村斗、农渠新建3条4.7km。长塘镇: 杨台村斗、农渠新建3条4km，柳溪村斗、农渠新建4条3.9km。乐安镇:乐兴村斗、农渠新建4条4km。4.2.2 技术方案1)项目区的支渠在多年运行中,均能结其范围内的所有农田实行自流灌溉,因此此次规划不改变原支渠的数量、走向和纵坡，仅在原渠道基础上进行渠道清淤、整修、加固及防渗。采用c15现浇砼衬砌，衬砌厚度底板和边墙均为80cm。工程量见下表2)斗渠规划 因项目区斗渠均为土渠，冲刷、淤积、渗漏严重，并且没有按设计要求进行开挖，水的利用率很低，仅达0.25，稻田灌溉问题一直没有得到解决。因此，规划在项目区新建斗渠。3）斗渠断面设计a 水量平衡计算工程的水源主要来自廖家坪水库，库区降雨丰沛，集雨面积大，达142.8km2，库容达4280万方，足可以保证稻田灌溉的需要，故水量平衡计算略。b、渠道设计流量的确定田间斗渠按支渠水流方向每100m设一条，其断面尺寸按灌溉面积100亩所需尺寸计算。工程措施实施后，田间渠道利用系数可达90%,故设计流量q设=q净/=qa/=0.6970.01/0.9=0.0077 m3/sc、断面尺寸的确定所有斗渠均采用c15砼现浇矩形断面断面尺寸由公式q设=wc(ri)1/2计算，式中w是渠道断面面积，c是谢才系数c=（1/n）r1/6，r是水力半径，i是渠道坡降，取1%0，渠道糙率系数n为0.018，q设=0.0077m3/s2，计算断面尺寸取0.4*0.3(m)，但考虑到排水效果，断面尺寸取0.4*0.4(m)。其它斗渠断面尺寸同等方法计算。计算成果及工程量见下表农渠断面尺寸按同样方法计算,计算成果及工程量见下表4）渠道防渗衬砌设计本次规划对5个项目区4条支渠10 .4km,斗渠15条19km , 农渠23条17.4km进行防渗衬砌。采用的防渗措施是c15砼现浇衬砌。支渠底板、边墙衬砌厚度均为8cm，斗渠和农渠底板衬砌厚度7cm，边墙衬砌厚度为8cm，工程量具体见下表（三）、项目建设管理和组织落实项目建设涉及到水利、农业、财政等部门以及有关乡镇、村、农户，情况较复杂，为了搞好小型农田水利工程建设，由县政府组织成立小型农田水利工程建设领导小组，负责组织和协调项目区建设有关事宜，项目主管单位为安化县水利局，承建单位为项目区乡镇水管站，项目责任人为各项目村负责人，负责工程质量，确保项目区工程建设高效、优质完成。项目区的建设将按照有关规定统一标准，统一规划，引进、推广、应用、开发各种先进技术，坚持高标准、严要求，加强工程的科学化、规范化、制度化管理，确保工程效益的最大发挥。五、投资估算及资金筹措（一）、投资估算1、编制依据本次规划依据湖南省水利水电工程设计概（估）算编制规定（湘水建管200816号文）、2002116号文发布的水利建筑工程概算定额、水利建筑工程预算
