摘　　要：分析了甘肃省主要河流的泥沙分布情况,水土流失地区主要分布在黄河流域。对地表水、地下水环境质量和主要河流水资源质量进行了评价,甘肃境内长江流域河流水质较好,内陆河流域次之,黄河流域河流矿化度和总硬度均最高。甘肃省水污染重点河段主要分布在重点工业区、人口密集城镇和造纸等高污染行业区,水资源保护的任务十分繁重。通过水环境质量分析评价,为河流水环境保护及流域生态环境保护提供科学的决策依据。This paper analyzed the sediment distribution in the main rivers in Gansu Province.The areas of water and soil erosion are mainly located in the Yellow River Basin.This paper assessed the water environment quality of surface water,groundwater and water resources quality in the main major rivers.The water quality in the Gansu reach of the Yangtze River is better,the followed are the inland rivers.The river mineralization and total hardness of the Yellow River is highest.The major river reaches of water pollution are mainly located in the important industrial areas,densely populated towns and highly polluted industrial sections,such as paper-making industry,so the task of water resources protection is quite heavy.The assessment provided a scientific basis of decision making for water environment protection and ecological environment protection of the rivers.
