摘要
为了保护和整治小型工业城市的生态环境,以北方典型小工业城市——沙河市为例,开展了小城市生态敏感性评价研究.沙河市目前面临水资源贫乏、水污染和大气污染严重、森林资源匮乏和生物多样性单调等众多环境问题,已经严重制约了该区域的发展.在分析其区域生态景观基础特征的基础上,应用GIS技术,采用多因子加权求和方法,对环境较为脆弱、生态相对敏感的沙河市大沙河古河道地区进行生态敏感性综合评价,并在此基础上提出相应的生态敏感性分区保护策略,为古河道地区进行生态建设和环境保护提供了依据.
In order to protect environment and regulate environment, some research has been done on eco-sensitivity of small-sized city, taking Shahe city as an example, which is a typical sn^all-sized industrial city in northern China. Shahe city is currently facing a series of environmental problems, such as a searity of water resources, serious water pollution and air pollution, shortage of forest resources and monotonic hiodiversity, which have severely constrained the development in this region. Based on the analysis of its regional ecological landscape features, GIS technique and a multi-factor weighted sum method were used to make comprehensive eco-sensitivity evaluation on ancient river bed of Dasha river, which has comparatively fragile environment and sensitive ecology. On this basis, it advanced corresponding protection strategies on this eco- sensitive region and provided foundations of ecological construction and environmental protection in this ancient water-course.
