1990-2020年汾河流域耕地利用隐性转型时空分异及其驱动力
Spatiotemporal differentiation and driving forces of implicit transformation of cultivated land utilization in Fenhe River Basin from 1990 to 2020
摘要
Abstract
[Objective]This study aims to characterize the implicit transformation and differentiation of cultivated land use,uncover the underlying patterns of its evolution,and provide a scientific basis for ensuring food security and optimizing cultivated land resource allocation in the Fenhe River Basin.[Methods]Based on remote sensing image data on land use from 1990,2000,2010,and 2020,along with socio-economic data,an index system was developed across three dimensions:inherent input,output capacity,and functional evolution.The entropy method,spatial autocorrelation analysis,and geodetector were employed to investigate the spatiotemporal differentiation and driving forces of the implicit transformation in cultivated land use.[Results](1)From 1990 to 2020,the implicit transformation index of cultivated land utilization in the Fenhe River Basin steadily increased from 0.091 0 to 0.289 5,representing a rise of 218.13%.Spatially,the index exhibited a pattern of higher values in the south and lower values in the north,with a clear trend of spatial agglomeration.(2)From the perspective of functional evolution,the cultivated land in the Fenhe River Basin had the highest production function index,followed by the social security function,while the ecological function was the lowest.(3)The implicit transformation of cultivated land utilization in the Fenhe River Basin was driven by a combination of natural and socioeconomic factors.Among these,agricultural output value,total agricultural machinery power,chemical fertilizer application,and grain crop yield per unit area exhibited particularly strong explanatory power for such transformation.[Conclusion]The implicit transformation index of cultivated land utilization in the Fenhe River Basin from 1990 to 2020 has exhibited a consistent trend toward optimization,contributing to the high-quality development of agriculture and the comprehensive revitalization of rural areas in the region.关键词
