新疆耕地景观细碎化演变特征及驱动因素
Evolution characteristics and driving factors of farmland landscape fragmentation in Xinjiang
摘要
Abstract
[Objective]This study aims to examine the spatiotemporal evolution characteristics and driving factors of farmland landscape fragmentation in Xinjiang,providing a theoretical basis for optimizing regional farmland resource allocation and promoting large-scale use of farmland in Xinjiang.[Methods]Based on the land use data of five periods from 1980 to 2020,GIS methods were used to measure the fragmentation of farmland landscapes in Xinjiang from a landscape pattern perspective.Additionally,geographic detectors were employed to explore the driving factors of fragmentation.[Results]The degree of farmland landscape fragmentation in Xinjiang was relatively high,but it generally showed a decreasing trend.During the study period,the farmland landscape fragmentation index decreased by 4.00%,with counties at moderate,high,and very high fragmentation levels decreasing by 13.67%,1.29%and 4.22%,respectively.In contrast,counties at low and relatively low fragmentation levels increased by 7.13%and 12.25%.The change characteristics of landscape fragmentation varied significantly over different periods.From 1990 to 2010,the degree of farmland fragmentation decreased most significantly,with large changes,a wide range of dimensions,and a broad impact across counties.The spatial distribution of landscape fragmentation trends was significant:the increasing fragmentation trend concentrated in counties north of the Kunlun Mountains and near the Turpan Basin,while the decreasing trend was mainly concentrated in counties on the southern and northern slopes of Tianshan Mountains and the northwestern edge of the Tarim Basin oases.The degree of landscape fragmentation was mainly influenced by a combination of factors such as slope,distance to built-up land,distance to water and elevation.[Conclusion]Over the past 40 years,farmland fragmentation in Xinjiang has improved to some extent,but significant differences in fragmentation levels remain across counties.It is necessary to further strengthen the regional-specific comprehensive management of farmland fragmentation,taking into account topography and location,to promote the large-scale development and sustainable utilization of farmland resources in Xinjiang.关键词
