乡镇尺度下河流生态系统健康评价:以宜昌市良斗河为例
|
摘要
为探明乡镇尺度下河流健康状况,采用层次分析法、BP神经网络和赋分法评价良斗河河流健康程度。健康等级评价结果表明:全流域8个样点中,有50%的样点为Ⅰ级,37. 5%为Ⅱ级,12. 5%为Ⅲ级。健康状况较好的样点主要分布在河流上游,随径流河流健康状况逐渐变差,良斗河河流生态系统健康状况具有较强的空间异质性。单因子评价结果显示:引起各乡镇河段生态系统健康状况变化的主要因素各不相同,水环境指标的影响最为突出,是良斗河健康评价中必不可少的指标类型。
In order to study river health status located in township scales,this paper was based on the analytic hierarchy process,BP neural network and the score method to evaluate the health of the Liangdou River. The result indicated that:among the eight samples in the whole basin,50% of the samples were grade Ⅰ,37. 5% are grade Ⅱ,and 12. 5% were gradeⅢ. The samples with better health status were mainly distributed in the upper reaches of the river. The upstream was better than the midstream and downstream where the spatial heterogeneity of the health condition was stronger. Results of single factor evaluation showed that the reason of the descent of the health status in each township river section was different in its own way.However,water environment indicators played the most significant role in the health status of Liangdou River.
