| 摘 要： | 通过对南通市环境质量数据的分析,运用模糊综合评价和G IS方法对南通市环境质量现状做了综合评价,完成环境质量专题区划图,直观地反映了南通地区环境质量总体状况。研究发现环境质量“很好”和“一般”的地区占整个区域面积74.4%,南通市环境质量状况总体较好。从空间分布来看,中部经济发展水平较高地区环境质量相对较差,两侧经济发展水平较低地区环境质量相对较好。运用基于G IS的模糊评价方法进行环境质量评价具有定性、定量与定位相结合的特点,评价结果直观清晰。

| Abstract: | After analyzed the data of environment quality in Nantong area,we made apprehensive evaluation by the method of fuzzy evaluation and GIS.We completed the classification-zoning divisions of Nantong environment quality,which reflected the whole environment state of Nantong area.According research,we got a conclusion that the area whose environment quality was on the level of "very good" and "commonly" taks 74.4% of whole Nantong area,so that the environment quality of Nantong was relatively good.By the spatial distributing, we found that the middle area of Nantong whose economy developed rapidly had the worse environment,and the biside areas of Nantong,whose economic development droped behind had the cleaner environment.The method of fuzzy evaluation of environment quality based on GIS gathers the advantage characters of fuzzy evaluation and GIS,and realizes the evaluation result visible. |
