十大孔兑复合侵蚀区泥沙阻控与近自然生态修复关键科学技术问题
Sediment Control and Near-Natural Ecological Restoration in Wind-Water Complex Erosion Area of the Top Ten Tributaries
摘要
Abstract
Soil and water loss in the sandstone area of the upper top ten tributaries is very serious with severe water erosion of the area,seri-ous difficulty to control soil loss,large amount of soil into the Yellow River and poor stability of ecosystem.The objectives of this paper,namely the scientific and technical issues in the study,were to analyze the driving mechanisms of complex erosion and flood-sand production and transport in the top ten tributaries,determine the generalized water carrying capacity and thresholds for maintaining the stability of vege-tated ecosystems,and develop the sediment control technology and near-natural ecological restoration technique in the area.Six major re-search components were listed based on the elaboration of the background of sand prevention and sand control and the current status of re-search in the Yellow River Basin:a)Recognizing the process of wind-water composite soil and water erosion,and zoning of ecological resto-ration space for rational disposal of water and sand.b)Researching and developing the sediment deterrent and control technologies based on different ecological restoration space layouts and optimal allocation of native plants.c)Researching and developing of multi-dimensional ter-raced synergistic management technology for mountains,water,forests,fields,lakes,grasses and sands.d)Researching and developing techniques for maintaining the stability and improving the quality of artificially degraded vegetation based on rigid water resources constraints.e)Building a diversified near-natural ecological restoration technology system and model.f)Demonstration study on Hantaichuan gullied roll-ing loess area,Dalat"Three-North"Project management area and Heilaigou Engebei ecological building area.关键词
