Efficiency and Influencing Factors of Soil Erosion Control in Yellow River Basin from the Perspective of Water Conservancy Construction
摘要
Abstract
From the perspective of water conservancy construction,taking the Yellow River Basin as the research object,the efficiency of soil erosion control is calculated with the DEA-BBC model and its key influencing factors are analyzed with the Catboost model.The research results indicate that 1)water conservancy construction is closely related to soil erosion control and economic development,and water conservancy construction generates significant environmental and economic benefits.2)The efficiency of soil erosion control is ideal in the upper and middle reaches of the Yellow River,but needs improvement in Henan and Shandong provinces in the lower reaches.In the non-DEA effective state,scale returns increase in Henan and decrease in Shandong.3)Population,agricultural development,environmental investment and construction,and precipitation are key influencing factors for soil erosion control efficiency in the Yellow River Basin.关键词
