摘　　要：1996~1999年,在庐山自然保护区核心区,依据国家环境监测技术规范,利用水质综合污染指数对9个主要水体进行了水质评价,同时利用底栖大型无脊椎动物科级生物指数进行评价.两种指数显示出相同结果:1个基点(大月山水库)水质清洁,5个基点(芦林湖、黄龙潭、一级电站、二级电站、三级电站)水质轻污染,3个基点(东谷溪流、电站水库、如琴湖)水质污染.在山地中小水体,利用底栖大型无脊椎动物科级生物指数可作为水质综合污染指数的有益补充,两种指数相结合进行评价更能反映水质实际状况.Water quality of 9 main sites were evaluated using the synthetic pollution index(PI) according to the National Environmental Monitoring Technical Norms at the central area of Lushan Mountain natural reserve from 1996 to 1999. Meanwhile, the water quality was assessed using the family-level biotic index(FBI) of benthic macroinvertebrates. The results from these two indices showed the same results: the water quality of one site (Dayueshan Reservoir) was clear; 5 sites(Lulin Lake, Huanglong Pond, the 1storder hydropower station, the 2ndorder hydropower station, the 3rdorder hydropower station) were slightly polluted; and 3 sites(the stream of Eastern Valley, the reservoir of hydropower station and Ruqin Lake) were polluted. For small water bodies in mountainous region, two indices should be combined to evaluate so as to reflect the real situation of water quality, with the latter indice as beneficial complement to the former.
