Sustainable Water Resources Use in Soil-Erosion Areasin Upper and Middle Reaches of the Yellow River
黄河中上游水土流失区水资源可持续利用模式

The main inconsistency between economic development,resource shortage and environmental deterioration in the Region with water and soil erosion in the Loess Plateau are becoming more and more evident.The population growth is tended to accelerate while the educational level is still kept at a relatively low level;the traditional water resources use is with a view of regulating surface water and ground water through project;water and soil erosion are increasing and capacity of soil water-holding is decline;the drought in the spring season restrict the production of agriculture seriously;the lower yield leads to the low income of farmers.The paper put forward the mode of sustainable utilization of water resources in areas suffering from soil and water loss in upper and middle reaches of Yellow river.The mode consists mainly of five aspects: 1) controlling population growth,enhancing the quality of population and encouraging people to go out of those areas to work in order to alleviate the population pressure on the unit land;2) taking all sorts of measures to enhance the efficiency of water resource use based on reasonable and effective utilization of surface water and ground water;3) promoting actively water and soil conservation.The main measure is to transform slope land into terrace and increase the capacity of soil water-holding;4) implementing rainfall harvest project to gather rainwater for supplementary irrigation and extending feasible techniques of water-saving irrigation;5) adjusting the structure of agriculture production,developing ecological agriculture and multi-economy,promoting the protection of environment,promoting economic development and increasing farmers' income.
