1986-2023年东昆仑库木库里盆地湖泊变化及成因分析
Lake change and genetic analysis in east Kunlun Kumukuli Basin from 1986 to 2023
摘要
Abstract
Conducting a systematic study on lake area changes and their underlying causes in the east Kunlun Ku-mukuli Basin holds significant practical importance.This research enhances our understanding of climate change patterns and the regional water cycle in the east Kunlun Mountains,addressing critical water shortage issues in southern Xinjiang,China.Utilizing the Google Earth Engine(GEE)remote sensing cloud computing platform,this study extracted water bodies from remote sensing images of the east Kunlun Kumukuli Basin between 1986 and 2023.It analyzed lake area changes and their influencing factors,incorporating meteorological data,glacier activity,and land use patterns.The findings reveal several key trends from 1986 to 2023.(1)The number and area of lakes in the east Kunlun and Kumukuli regions increased significantly,with the total lake area expand-ing from 1196.47 km2 in 1986 to 2190.43 km2 in 2023,representing an average annual increase of 26.16 km2.(2)Ayakumu Lake,the largest in the region,experienced a 50.17%increase in area,while the number of lakes larger than 1 km2 grew from six in 1986 to nine in 2023.(3)The primary driver behind this lake expansion is moderate precipitation,which accounts for 63.80%of the increase.Although air temperature plays a role in gla-cier melt,its contribution to lake area growth is less significant than that of precipitation.关键词
