摘要
文章利用韦伯-费希纳定律建立区域生态环境评价的新模型,并通过实例研究了区域生态环境质量状况,即巢湖流域总体以及分区巢湖市、六安市的生态环境质量为Ⅵ级、分区合肥市为Ⅲ级。与未确知测度评价方法进行比较,取得了满意的结果,实例应用表明:该评价模型结构严谨,评价结果合理,为区域生态环境质量评价提供了一种简单而适用的评价方法。
This paper used Weber-Fechner law to establish a new regional ecological environment evaluation model,and studied regional ecological environment quality conditions through case study.The results were as follows: the ecological environment quality of the whole Chaohu basin and its sub-region Chaohu and Liu'an are Ⅵ grade,and the sub-region Hefei is Ⅲ grade.Compared with unascertained measurement evaluation method,our approach achieved satisfactory results.The case study showed that,this evaluation model had tight structure,and evaluation results were reasonable,precise and with high resolution.Thus,a simple and effective evaluation method was provided for regional ecological environment quality evaluation.
