Control technology of gully sediment yield in Yellow River basin

The ecological protection and the high quality of national strategic in the Yellow River is pointed out that the Yellow River basin management to adhere to the concept of Lvshui Qingshan is the Jinshan Yinshan, strive to strengthen management of ecological protection, promote the implementation of a batch of major ecological restoration and construction projects, including Pisha stone areas in the middle reaches of the Yellow River is to focus on one of the areas to carry out the comprehensive control of ecological. Based on the analysis of the previous treatment theory and practice in the Pisha stone area, the research and development of the ecology-economy comprehensive treatment technology in the Pisha stone area is carried out. Including slope runoff efficient reservoir and utilization technology, the top economic fruit industry mode, block polymer grouting treatment technology of gravity erosion, slope erosion resistance and comprehensive treatment technology, flexible dam-Pisha stone channel modification material check dam and warping DAMS erosion prevention and control technology research and development and integration, finally enhance sieved Pisha stone areas are summarized ecological comprehensive control mode. The comprehensive ecological management model of Pisha stone can provide strong technical support for ecological protection and high-quality development of the Yellow River Basin.
