苏州市环境敏感地的划定研究

Research on Delimitation of Environmentally Sensitive Area in Suzhou City

工业化和城市化进程的迅猛推进促使人类开发与建设活动不断侵占坡地、优质农田等环境敏感地区,产生了众多生态环境问题,影响了区域可持续发展。针对不同类型区域的特点,对环境敏感地进行分类,划清区域未来开发与保护的界限,对实现区域健康发展具有重要的现实意义。论文从环境敏感地对经济发展的保障与支撑能力以及环境敏感地在苏州全市域生态功能保护区的重要性程度为出发点,将苏州市环境敏感地划分为生态功能敏感地、地表水源敏感地、污染影响敏感地、优质农田敏感地和潜在灾害敏感地5类,并进一步明确其空间分布范围,为苏州市建设用地扩张控制、资源管理、生态保护提供了理论依据。

Along with the industrialization and the urbanization process, the human being＇s activities of developments and constructions turned to the environmentally sensitive area unceasingly, which has created many environment negative problems against regional sustainable development. In view of the different types of characteristics regions, the classification to environmentally sensitive area, and clear distinction of the boundaries between the future regional development and protection, are of vital practical significance to the realization of the regional economic sustainable development. From the safeguard and support capacity of environmentally sensitive area to economic development and the importance of ecological function protected area of Suzhou City ,the environmentally sensitive area of the city will be divided into the ecological sensitive area, surface water source sensitive area ,contaminated sensitive area, high quality farmland sensitive area as well as the latent disaster sensitive area, five kinds in all. The defination of its spatial distribution can be testified from this contest,which has provided the theoretical basis for municipal building land expansion control, resource management and ecological protection.
