疆电外送通道土地覆被时空变化及驱动力分析
Spatial-temporal changes and driving forces analysis of land cover in"Xinjiang power transmission"corridor
摘要
Abstract
Exploring land cover change is very important for the sustainable development of regional land resources.However,there are few studies on land cover change in the construction of Xinjiang e-lectricity transmission energy channel.In this paper,the temporal variation characteristics of land cover in a 10 km buffer zone along Jiquan Line in Changji Hui Autonomous Prefecture were analyzed by using multi-scale geographically weighted regression model(MGWR)to explore the spatio-temporal changes and driving factors of land cover in this region during 2010-2022.The results showed that:① Grass-land,bare land and cultivated land were the main areas in the study area,and the proportion of grass-land and bare land was more than 90% .During the construction of Xinjiang electricity transmission channel,the land cover changes were more drastic and complicated;② There are differences in the driving factors in terms of time.In the preparation and formal construction stages of the channel con-struction,the distance to the base station and the distance to the power grid rank first and second re-spectively in importance.However,during the operation period after the construction is completed,the distance to the water source and the minimum temperature rank first and second respectively.③ The spa-tial ranges of different factors are different.Annual minimum temperature and distance to water source mainly affect grassland,bare land and farmland.The research results can provide reference for the con-struction of similar projects in the future,and promote sustainable land use and ecological protection.关键词
