| 摘 要： | 基于河流生态系统健康的内涵,建立包括河流自然结构、生态系统、社会服务等3个方面12个指标的河流生态系统健康指标评价体系.以梅江河主干流为例,通过应用评价方法和数学模型,对梅江河多个河段进行综合评估.结果表明:梅江河总体健康指数为0.611,处于"基本健康"等级状态,但其社会服务指数较低,为0.521,主要由于河道水质和通航情况不良.

| Abstract: | Based on the connotation of river ecosystem health,the index and evaluation system was built by three aspects of 12 indicators which including river natural structure,ecosystem,social services.Taking the main stream of Meijiang River for example,overall evaluations of many of the river were made by using evaluation method and mathematical model.The results show that although Meijiang River was in a state of＂basic health＂ level because of the overall health index that was 0.611,the index of social services which was less than 6 points was not good enough.It was because of the pollution of river water quality and navigation obstruction. |
