34、基础,集聚发展要素,增强发展后劲,以此促进县域经济快速发展。一、全县城镇建设的现状近年来,按照高点定位、建管并举、提质扩容的思路,在扩张县城规模上向北扩展、向西延伸、向南开发,在提升建设品位上注重自然、人文,高起点规划,大力度实施,城市功能进一步完善。县城建成区面积达7.83平方公里,城区人口达到11.5万人,城镇化水平达到28%,城区绿地覆盖面积达到66万平方米, 2008年顺利通过了省级卫生县城验收。但按照科学发展观的要求来衡量,仍然存在着城市规模小、基础设施配套和管理不到位、城乡建设不协调等不符合、不适应科学发展的突出问题,必须切实加以整改完善,建立符合科学发展观的体制机制,推动城市建设
35、持续健康发展。二、科学推进城市建设管理科学推进城市建设,规划是龙头,建设是基础,管理是核心。按照“持续、完善、巩固、提升”的要求,在具体实践中处理好四个方面的关系。一是统筹规划与建设的关系。在城市开发建设中,要首先保证规划的龙头地位,统筹协调城市人口、产业基础设施、生态环境和资源等城市化要素,以规划的科学性、完整性、严肃性保证城市建设的高品位、多功能。二是统筹县城开发与乡村发展的关系。城镇对农村的影响最直接,增强小城镇的辐射和带动作用是统筹城乡发展成本最低、效果最明显、操作最简便的途径,把促进农村城镇化、城乡一体化放在更加突出的位置,努力实现城乡发展良性互动。三是统筹基础设施和生态环境的关系。
36、必须把保护环境放在首位,注意克服破坏生态、浪费资源等各种问题,不能以牺牲资源和环境为代价来换取城镇一时的快速扩展。四是统筹城市建设与城市管理的关系。把城市管理放在突出位置,坚持统一规划、统一管理、统一投入,把管理工作渗透到城市建设和发展的各个环节,推动城市的经济效益、社会效益、生态效益相互促进、协调发展。在处理好四个方面关系的基础上,按照“丰富文化内涵、提高城市品位、完善基础设施、增强服务功能”的思路,坚持速度、质量相统一,把握关键环节,不断完善城市功能。1、加快完善城乡规划编制。一是注重规划的完整性。按照“土地集约、人口聚集、功能完善、产业集中、城乡协调”的总体要求,合理配置土地资源,发挥土
37、地的最大效益,加快完成专项规划和区域规划,进一步完善规划体系。二是体现规划的科学性。采取“走出去、请进来”的办法,外出学习借鉴先进经验,邀请专家、教授出谋划策搞规划,切实提高我县城镇建设规划设计水平。三是维护规划的严肃性。坚持不符合城市规划的项目不得批准立项,未编制控制性详细规划的不得供地,保证任何建设项目都不突破规划控制范围。2、强力推进“三区一带两支撑”建设。把“三区一带两支撑”建设作为推进城乡一体化的重要举措,重点在基础设施建设、企业引进、产业培育等方面下功夫,促进城乡协调发展。农业产业园区要建立高效灵活的管理开发机制,制定有利于园区发展的优惠政策,为企业提供便利服务。北河坪新城区要在城
38、区总体规划框架内,编制详细建设性规划,为有序开发提供依据;坚持基础先行,报批储备土地,多渠道筹措资金,积极稳妥推进开发进程,努力建设集行政、文化、人居、商贸等为一体的功能完善的新城区。郭城工业集中区要按照规划,组建管理运行机构;制定管理办法和优惠政策,以良好的服务环境吸引投资;依托现有企业布局,与小城镇建设相结合,实施道路、供排水、绿化亮化等工程;发挥企业的主体作用,加强行政推动,扩大现有企业规模,引进一批新的企业入驻,为集中区发展积聚人气、商气和财气。3、突出抓好城区综合管理。一是尽快组建城市管理综合执法机构,整合执法资源,探索城市管理长效机制,力争城市管理早日步入正常转道。二是细化责任。进一步完善城市市场管理、交通管理、社会治安管理等方面的规章,将城市管理职责细化、量化到相关职能部门和单位,做到管理无缺位,落实无死角,杜绝相互推诿扯
