Study on the eco-agriculture construction and sustainable development in Jinghe watershed

Based on the research on the eco-agriculture environment characters in Jinghe watershed, a strategy of focusing on vegetation rebuilding, integrating the big rivers and the branch rivers, and taking the little watershed as the unit to comprehensive control was proposed. According to the advantage of arid fanning in the loess tableland and stream plain, efforts should be given to improve the land productivity and develop the efficient arid farming system. Taking the well-ordered circulation of restoring agriculture ecosystem as the critical problem, the adjustment on land use structure can be made through conversion of cropland to forest and grassland and restructuring on agriculture production structure. In order to accelerate the regional economic development, new feature alternative industries should be reinforced, and the harmonized eco-environment improvement and economic development should be promoted.
