摘要
1998— 2 0 0 0年的研究结果表明 ,千岛湖的富营养化进程明显加速。千岛湖上游安徽境内输入的大量营养盐、周边地区的生态环境变化、农田地表径流及水土流失是引起湖水水体质量变化的主要原因。控制上游安徽境内的入湖水质、减少农业面源污染和水土流失对水体的影响、恢复与重建湖滨植被保护带。
The eutrophication and the soilerosions were main eco-environmental problems in Qiandao Lake. The main reason of above situation is the pollutions from the catchment basin in the Anhui province. Soil and water loss and fertilizer and pesticide leaching that formed by sloping field assart and inadequate forestation were the improving factors of the lake's eutrophication. For the lake eco-environmental protection, it is very important that the restoration of vegetation in lakeshore, to control non-point pollutions from agriculture, to prevent the soil erosions.
