| 摘 要： | 湿地是自然界生物多样性较为丰富的生态系统,具有很大的生态功能及生态学价值,湿地水质评价需要综合考虑各指标的属性.介绍了基于改进熵权的灰色关联模型在湿地水质综合评价中的应用.以黑龙江省扎龙国家级自然保护区湿地调查采样数据为例,通过构建灰色关联决策矩阵,同时采用改进熵值法确定权重,再由计算各样本的灰色关联度来确定其所属级别,进而对保护区水质采样点的水质进行综合评价.基于改进熵权的灰色关联度模型,为湿地生态系统水质综合评价提供了新的思路.

| Abstract: | This paper is focused on the study how to apply gray relevancy model based on ameliorated entropy to comprehensive evaluation of wetland environmental quality. First of all,it has introduced the concept of the gray relevancy model,including listing the analysis sequences,the ways to construct the decision-making matrix of gray relevancy,calculating the maximal and minimal differences,calculating the relevance coefficients,etc. On top of that,we have put forward the drawbacks of the entropy-method and thereb... |
