国务院办公厅关于批准衡阳市城市总体规划的通知

国办函〔2006〕94号

湖南省人民政府:

你省《关于审批〈衡阳市城市总体规划(2002-2020)〉的请示》收悉。经国务院同意,现通知如下:

一、原则同意修订后的《衡阳市城市总体规划(2006年-2020年)》(以下简称《总体规划》)。

二、衡阳市是湖南省南部的中心城市。要以科学发展观为指导,坚持经济、社会、人口、环境和资源相协调的可持续发展战略,统筹做好衡阳市城市规划、建设和管理的各项工作。按照合理布局、集约发展的原则,有重点地发展现代加工业、物流业和旅游业,不断完善公共服务设施和城市功能,把衡阳市建设成为经济繁荣、社会文明、生态良好,具有地方特色的现代化城市。

三、重视城乡统筹发展。在《总体规划》确定的1114平方公里的城市规划区范围内,实行城乡统一规划管理。以调整、改造、挖潜为主,逐步完善中心城区功能,强化中心城区与周边城镇的经济联系。要按照促进城乡经济社会统筹协调发展的要求,根据市域内不同地区的条件,加强城乡发展统筹规划,重点发展湘江沿岸和京珠高速公路、京广线沿线城镇,逐步形成布局合理、功能明确、结构完善的市域城镇体系,带动农业产业化和农村经济发展。

四、合理控制城市规模。到2020年,主城区实际居住人口控制在130万人以内,建设用地控制在120平方公里以内。具体规模要与你省省域城镇体系规划和土地利用总体规划相衔接。要根据衡阳市环境、资源的实际条件,强化集约和节约用地,采取切实措施保护好耕地特别是基本农田。充分重视对城市地下空间的开发利用,防止城市规模盲目扩大。

五、完善基础设施体系。要重视交通基础设施建设,建立公路、铁路、水运

和民航相协调的交通运输系统。建立以公共交通为主体,多种交通方式相结合的多层次、多类型的公共客运服务系统。统筹规划建设城市给水、排水和污水、生活垃圾处理等基础设施。充分重视城市防灾工作,加强重点防灾设施和灾害监测预警系统的建设,建立包括消防、防洪、抗震和人防在内的综合防灾系统。

六、加强资源环境保护。城市发展要走节约资源、保护环境的集约化道路,根据节流、开源、保护并重的原则,节约和集约利用水、能源等资源。要提高水资源利用效率,建设节水型城市。依靠科技进步,大力发展循环经济,强化工业、交通和建筑节能。加强对自然保护区、森林公园、水源地和衡山风景名胜区等特殊生态功能区的保护。坚持经济建设、城乡建设与环境建设同步规划、实施和发展,严格按照规划提出的各类环保标准限期达标。加强城市环境综合治理,严格控制和治理湘江干、支流的水污染。

七、创造良好人居环境。城市功能要以人为本,创建宜居环境。切实做好关系人民群众切身利益的教育、医疗卫生、市政等公共服务设施的规划布局。将普通商品住房、经济适用住房和廉租住房的建设目标纳入近期建设规划,从方便低收入群体的生活与就业出发,保障经济适用住房和廉租住房用地的分期供给规模、区位布局和相关资金投入。根据城市的实际需要与可能,稳步推进旧城改造特别是危房改造工作。

八、重视风貌特色保护。要加强对市域内各级文物保护单位和风景名胜资源的保护,划定保护范围,制订保护措施并严格实施。依托湘江、蒸水、耒水等“三水六岸”构建城市滨水景观区,加强滨江带状绿地和城市主要道路两侧绿化带建设,形成与衡山风景名胜区相呼应,富有丘陵地区滨江城市特色的景观风貌。

九、严格实施《总体规划》。《总体规划》是衡阳市城市发展、建设和管理的依据,城市规划区内的一切建设活动都必须符合《总体规划》的要求。要抓紧深化近期建设规划和有关专业规划,建立健全城市规划、建设和管理的各项制度。城市规划行政主管部门要依法对城市规划区范围内的一切建设用地与建设活动

实行统一、严格的规划管理,切实保障规划的实施。驻衡阳市的各单位都要遵守有关法规及《总体规划》,支持衡阳市人民政府的工作,共同努力,把衡阳市规划好、建设好、管理好。

衡阳市人民政府要根据本通知精神,认真组织实施《总体规划》,任何单位和个人不得随意改变。你省和建设部要加强对《总体规划》实施的指导、监督和检查工作。
