| 摘 要： | 基于生态系统可持续发展理论,构建了由社会、经济、自然环境和自然灾害4个子系统和28个2级指标组成的湿地生态环境质量评价指标体系;以信息熵理论为基础建立了客观确定权重的综合信息熵模型,层次分析法和综合信息熵模型法相结合确定指标权重;采用灰色关联模型对湖南省重要湿地2002~2006年生态环境质量进行评价。结果表明:湖南省重要湿地生态环境质量整体上属中等水平;洞庭湖、官庄、青山垅湿地综合评价值较低,生态环境质量较差;涔天河、酒埠江、黄石、凤滩、铁山生态环境质量为中等;东江湖、双牌和柘溪湿地生态环境质量始终处在良好水平。

| Abstract: | Based on the ecological system sustainable developmental theory,this paper built the wetland ecological environment quality evaluation index system consisted of four subsystems:society,economic,natural environment and natural hazard as well as 28 second grades.Based on information entropy theory,the Information Entropy Model(IEM) was established to calculate the weight of every index.The index weight was determined by the combination of layer analysis method and colligation information entropy model method;... |
