农业景观破碎化时空演变特征及其驱动力研究
Study on the Spatial and Temporal Evolution Characteristics and Driving Force of Agricultural Landscape Fragmentation-Taking Zhuzhou City as an Example
摘要
Abstract
Scientific evaluation of agricultural landscape fragmentation is fundamental to achieving agricultural ecological security and is also a prerequisite for formulating effective ecological protection and restoration strategies and optimizing agricultural production layout.In this study,we investigated the spatiotemporal characteristics of agricultural landscape evolution and fragmentation in Zhuzhou City,Hunan Province,from 2000 to 2020,and used geographic detectors to reveal its driving mechanism.The results showed that the agricultural landscape of Zhuzhou City has undergone obvious spatiotemporal evolution,with a decrease in cultivated land area and an increase in forestland,mainly influenced by policies such as returning farmland to forestland.The degree of agricultural landscape fragmentation first increased and then decreased,showing a general trend of increasing first and then decreasing.Density of population,GDP density,and road network density have a high explanatory power for fragmentation,with the interactive effect of population density and GDP density being the most significant.This study provides scientific basis for agricultural landscape protection and planning,and is helpful for achieving landscape sustainability and spatial continuity.关键词
