陕西省生态环境对耕地利用生态效率的响应
Response of Ecological Environment to Ecological Efficiency of Cultivated Land Use in Shaanxi Province
摘要
Abstract
[Objective]The aim of this study is to explore the response mode and degree of ecological environment to the ecological efficiency of cultivated land use,which is of great significance for realizing the coordinated development of agricultural sustainable development and ecological environment protection.[Methods]Shaanxi Province was taken as the research area.Remote sensing ecological index was calculated to characterize the ecological environment quality of Shaanxi Province based on remote sensing data.SBM model was used to measure the ecological efficiency of cultivated land use in Shaanxi Province.The geographical weighted regression model was used to explore the response of ecological environment to the ecological efficiency of cultivated land use.[Results](1)In 2005,2010,2015 and 2019,the ecological efficiency of cultivated land use in Shaanxi Province was generally at the medium level,and more than 88% of the areas were classified as low efficiency,low efficiency and medium efficiency.(2)In 2005,2010,2015 and 2019,the ecological environment quality of Shaanxi Province was continuously improved,and the ecological environment quality of loess hilly and gully region and Mu Us Sandy Land were significantly improved,and the spatial pattern remained high level in the south and low level in the north in general.(3)There was a significant positive correlation between the ecological efficiency of cultivated land use and the ecological environment in Shaanxi Province,and the spatial distribution of the correlation relationship was unbalanced.[Conclusion]The synergistic development model of ecological environment and ecological efficiency of cultivated land use in Shaanxi Province is not stable,and needs to be further explored and consolidated.关键词
