基于GIS与层次分析的上海市蕴藻浜两岸生态环境综合评价

根据对上海市蕴藻浜的环境调查，分析了沿岸生态环境问题，采用层次分析和GIS技术相结合的方法，对上海市宝山区蕴藻浜两岸生态环境进行了评价，评价结果显示研究区目前适宜区为27.1％，较适宜区为15.1％，不适宜区为32.0％，最不适宜区为25.8％，在此基础上深入探讨了岸线占用率指标对生态适宜性评价的影响。结果表明，充分利用河流两岸和底泥中大量的微生物对河流水体中的污染物进行自然降解，将大大改善河流水质，在必须构筑河岸地段，可尝试利用生态砖材料代替浆砌石材料，从而减少人为破坏河流两岸原有生态系统。结合研究区生态环境现状，提出了蕴藻浜与黄浦江和长江 “三江合一”的规划，为上海市蕴藻浜的环境综合整治提供科学依据，同时该评价方法也可以为其他城市河流沿岸生态环境综合评价提供借鉴。

Assessment of the ecological environment suitability for the two banks of Yunzaobang River in Shanghai using GIS and analytic hierarchy process

Based on the ecological environment analysis according to the environmental investigation of the Yunzaobang River in Shanghai， we assessed the ecological suitability of land use in the area by combination of GIS and analytic hierarchy process. The results showed that the suitable， relatively suitable， unsuitable and relatively unsuitable areas were 27.1%， 15.1%， 32.0% and 25.8%， respectively. Furthermore， the effect of bank utilization rates on the ecological suitability was further discussed. The quality of the river water would be significantly improved if the natural degradation ability of the microbes in the substrate sludge and the two banks can be fully utilized. In order to reduce the influence of human activities on the ecosystem of the river bank， the stone\|laying of some river bank can be substituted by ecological brick material. Finally， the planning of “three river combination” for Yunzaobang River， Huangpu River and Yangtse River was proposed， which gives scientific support to the environmental treatment of Yunzaobang in Shanghai. Moreover， the assessment techniques can be used for the other similar area.
