喀斯特地区土地利用冲突识别与影响机制
Identification and mechanism of land use conflict in karst area
摘要
Abstract
[Objective]The aims of this study are to identify the spatial conflict of land use in karst area scientifically,to reveal its influencing mechanism,so as to seek the sustainable development path of regional land use.[Methods]Based on landscape ecological risk assessment,a land use conflict measurement model was constructed in the Lijiang River Basin,which was famous for typical karst landforms.The level and spatial-temporal evolution of land use conflict in the Lijiang River Basin from 1990 to 2020 were quantitatively analyzed.The influencing mechanism was further explored by using geographic detectors.[Results](1)During the study period,the level of land use conflicts in the Lijiang River Basin showed a slow decline,and the conflicts were mainly stable and controllable.The proportion of basically out of control and severely out of control fluctuated,gradually changed to controllable level,and the intensity of conflict was eased.(2)Land use conflicts had a banded spatial pattern of'high level in the middle and low level in the four regions',and the spatial heterogeneity was significant.The areas with high conflict value were concentrated in the main urban areas of various districts and counties in the basin and the areas adjacent to the main water system of the Li River,while the areas with low conflict value were mainly distributed in the surrounding mountainous and forest areas.(3)The intensity of land use conflict was comprehensively affected by natural environment,social economy and transportation location.DEM,slope,topographic relief,NDVI and road network density were the main influencing factors.[Conclusion]The land use conflicts in the Lijiang River basin are obviously changing,and the out-of-control areas are gradually transformed into controllable areas.In the future,ecological protection and restoration should be continuously promoted in the Lijiang River Basin to stabilize the regional land use structure and realize the sustainable use of land resources.关键词
