摘　　要：为探究茅洲河生态系统健康状况,通过2018年对茅洲河流域31个样点的水文、水质、地貌形态、水生生物和社会功能等指标所做的调研,运用层次分析法,建立河流健康评价体系,并对其健康状况进行评价.结果显示:在所调查的31个样点中,有19.35%为健康,61.29%为亚健康,16.13%为脆弱,3.23%为病态.茅洲河河流生态系统的健康状况总体处于亚健康,最高分为4.32,在茅洲河12(MZH12);最低分为1.98,在排涝河(PLH).茅洲河河流生态系统健康状况存在较强的空间差异性和干支流差异性,整体看来上游好于下游,干流好于支流.In order to explore the health status of the ecosystem of Maozhou River,the hydrological,water quality,geomorphology,aquatic organisms and social functions of 31 sampling points in Maozhou River Basin were investigated in 2018.The analytic hierarchy process was used to establish the river health evaluation system and evaluate its health status.The results showed that 19.35%of the 31 samples were healthy,61.29%were sub-healthy,16.13%were fragile and 3.23%were pathological.The health status of the river ecosystem in Maozhou River was generally sub-healthy,with a maximum score of 4.32 in Maozhou River 12(MZH12)and a minimum score of 1.98 in Pailao River(PLH).There were significant spatial differences between main and tributary branches in the ecosystem health of the Maozhou River.The overall view is that upstream is better than downstream and main streams are better than the tributaries.
