5、量情况。用水量分析石门卡水库位于新杭镇牛头山村，属在册重点小（一）型水库。水库的集水 面积6.58km2。水库以灌溉、防洪为主，兼有工业用水和水产养殖功能。（1）农业用水量水库设计灌溉面积为2000亩，本次按照2000亩计算。根据相关规，灌溉保 证率为75%根据计算，多年平均补充灌溉用水量 55万m，p=75%保证率补充灌 溉水量为66万m。由于灌溉技术水平的提高和灌溉工程的不断完善，规划水平 年灌溉用水定额将有所降低，节约的灌溉用水量可用于增加灌溉面积，因此，规划水平年的农业灌溉用水量将与现状水平基本相当。参照广德县卢村水库及省部分小型灌区的资料，渠系水利用系数为0.6。根据调查，水库下游农

6、田主要种植单季稻，作物需水集中在69月。同时，参考广 德县粮长门水库工程水资源论证报告（报批稿），其毛灌溉定额及需水量如表 5-4，其需水年分配系数见表5-5。表5-4农田毛灌溉定额及需水量计算表灌溉面积（亩）不同保证率灌溉定额（m3/亩）不同保证率需水（万 m3）50%75%90%50%75%90%2000290330360586672表5-5广德县单季稻灌溉需水年分配月份123456合计各月用水比重0 :000048.3%100%月份789101112各月用水比重24.0%23.6%4.1%000（2）工业用水量经调查，分析围以石门卡水库为水源的企业有广德独山南方水泥。广德独山 水泥取水量

7、为96.32万mVa。（3）生活用水经调查，该地区生活用水为自来水，不从石门卡水库取水。（4）渗漏损失量渗漏损失量包括水库对地下水补给损失和闸（坝）渗漏损失。闸（坝）渗漏 损失量是指坝基、两翼及周边渗漏三部分之和。坝基渗漏一般有实测资料，其它 两项可根据水文地质条件进行经验估算。 没有资料一般采用按闸蓄水量的百分比 进行推算，地质良好地区为0T%地质较差地区为1.53.0%。根据石门卡水库 水文地质条件，闸（坝）渗漏损失量按上个旬平均蓄水量的1%进行估算。（5）蒸发损失蒸发损失就是指水库蒸发损失。由于区域没有蒸发量观测资料，故借用临近 的广德气象站蒸发资料进行计算。（6）生态需水石门卡水库建成

8、以后，大坝下游河段减水，为保证减水段河道生态环境用水 需要，需要从水库下泄生态用水量。参考广德地区的广德县粮长门水库工程水资源论证报告（报批稿）»，在石 门卡水库坝址断面处，河道生态需水用 2个指标进行控制： 最小生态流量以生态基流进行控制， 生态基流采用90%保证率月平均流 量进行估算，对于石门卡水库，为 0.013m3/s，每年下泄40万m3。 年生态环境总需水量以多年平均径流量的百分比进行确定，北方为 1020%南方为2030%对于石门卡水库，多年平均径流量为 280.5万n3,取 20% 即 56 万 nBo因此石门卡水库日常下泄最小生态流量为0.013m3/s，年还需另外下

9、泄16 万m3的水量，以满足河道生态环境总需水量 56万m3的要求。(7) 建设项目需水项目取水3504m3/d，项目系统年生产运行时间为 330天，年取水量115.63 万m3三、设计容3.1典型年选取根据资料统计出1966年一2010年的降雨量，并绘制出频率曲线如 附图1, 可得95%寸应的数值为840.2，所以选取的典型年是1996年10月一1997年9月。 3.2水库来水量计算水库的来水量主要是降雨径流补给，经过对典型年降雨量的计算分析，可得 下表：区间来水量(万m3上旬中旬下旬PaFQ区间PaFQ区间PaFQ区间67.90.45 (5.85 209.30006.850.002.406
