Spatiotemporal pattern evolution of land use conflict in Urumqi City from the perspective of ecological security
摘要
Abstract
It is crucial to identify regional land use conflicts from the perspective of ecological security and effec-tively manage the coordination between urban development and land use.This study develops a land use conflict measurement model within the theoretical analysis framework of land use conflict and the pressure-state-response model,incorporating ecosystem service value and ecological risk evaluation factors.The spatiotemporal evolu-tion patterns of land use conflict in Urumqi City,Xinjiang,China,for 2000,2010,and 2020 are analyzed.Further-more,the future land use simulation model is employed to simulate and predict changes in land use conflict by 2030.The results indicate the following:(1)From 2000 to 2020,more than 73%of Urumqi's area was conflict-free or mildly conflicted.During this period,hotspots of land use conflicts expanded from the northern and south-western areas of Urumqi City to mountainous woodlands in the northern and southern regions,as well as near al-luvial fans on both sides of Dabancheng District's salt lake.The cold spot areas were primarily concentrated in the central urban region and within the mountainous woodland areas in the eastern and southern parts.(2)Natural factors such as climate,topography,and geomorphology remain the predominant drivers of spatial variations in land use conflict intensity.(3)A positive spatial correlation exists between the value of ecosystem services and land use conflict,whereas a significant negative spatial correlation exists between ecological risk and land use conflict.(4)In 2030,despite the substantial increase in Urumqi's land use zones with a high conflict rate,areas characterized by minimal or no conflicts continue to maintain their dominant position.This study provides a diag-nostic index system and methodology for analyzing the Urumqi land use conflict,and serves as an example and offers scientific support for an in-depth understanding of the spatiotemporal evolution characteristics and conflict mechanism of the Urumqi land use conflict.关键词
