Abstract

Soil and water conservation is an effective measure to ensure the sound operation of ecology, economy and society. The correct evaluation of the efficiency of soil and water conservation and its regional differences is an important prerequisite for optimizing soil and water conservation policies and measures. Taking Shaanxi Province as the research object, after counting and calculating the investment and total income of soil and water conservation from 2018 to 2019, the efficiency and spatial distribution of soil and water conservation in Shaanxi Province are analyzed by using the method of data envelopment analysis. The results show that the comprehensive technical efficiency of 18.2% of administrative regions in the province reached the best state, among which 82% of pure technical efficiency reached the optimal state and the gap between individuals was not large. Scale efficiency was the leading factor leading to the low comprehensive technical efficiency. There were obvious differences among cities (districts), showing the spatial distribution characteristics of high in the middle and low on both sides, high in the north and low in the south, high in the Yellow River Basin, and low in the Yangtze River Basin. Tongchuan was a key area to optimize the efficiency of soil and water conservation.
