摘　　要：为了解养猪污水灌溉对人工林集水区水质的影响,分别采用开"弓"型浅沟引流、均匀浇灌2种方式将附近养猪污水引入木荷×杉木混交林16个月(试验点1)、尾巨桉套种皇竹草人工林7 a(试验点2),并对集水区水质进行测定。结果表明:2个试验点森林集水区地表水环境质量总体良好,除微生物指标和试验点2锰含量超标外,2个试验点集水区地表水其它指标均符合生活饮用水卫生标准。试验点1污灌集水区地表水溶解性总固体、硫酸盐、氯化物、硝酸盐和试验点2溶解性总固体、铝、硫酸盐等指标较灌溉前地表水有所升高,但均低于生活饮用水卫生标准;试验点1污灌后集水区地表水总氮含量明显增加,超过地表水环境质量标准规定的Ⅴ类。In order to find out the effect of sewage irrigation on water quality in forest catchments,we irrigated mixture plantation of Cunninghamia lanceolata × Schima superba Gardn use swine wastewater by drainage ditch as ″弓″ for 16 months（the first point）,and sprinkling irrigated Eucalyptus urophylla × E. grandis intercropped with Pennisetum sinese Roxb for two years（the sencond point）. Water quality in plantation watershed was determined. The results showed that catchment surface water quality in both two points conformed to the standard for drinking water except microbial indicators in two points and manganese contents in the second point. Total dissolved solids,sulphate,chloride,nitrate of catchment surface water in the first point and total dissolved solids,aluminum,sulphate of catchment surface water in the second point more less than standard for drinking water,although higher than surface water without sewage irrigated. The total nitrogen of surface water in forest catchment increased significantly at the first point,and higher than V TN standard of Surface Water Environment Quality Standard.
