玛曲县不同土地利用类型对生态环境质量变化的响应
Responses of Different Land Use Types to Ecological and Environmental Quality Changes in Maqu County
摘要
Abstract
The aims are to explore the main influencing factors of remote sensing ecological index(RSEI)in Maqu County and find out the relationship between different land use types and ecological quality changes,to provide basic data for ecological protection and sustainable development in the Yellow River Basin.Based on remote sensing data,this paper analyzed the change characteristics of vegetation coverage and RSEI in Maqu County from 2000 to 2021.The results showed that:(1)the land use in Maqu County was mainly grassland,and the change of land types was not large from 2000 to 2021.The ecological environment quality showed a significant decline trend in 2011 and 2017,and the environmental quality increased significantly in 2021.(2)The area of ecological degradation in Maqu County from 2000 to 2010 was 4484.72 km2,and the area of ecological improvement from 2011 to 2021 was 8374.59 km2,with an increase of nearly 70.05%,and the area of ecological quality improvement increased significantly.(3)From 2000 to 2021,the transfer of land use types in Maqu County was mainly between forest land and grassland.The ecological environment quality of Maqu County was closely related to vegetation cover,humidity and altitude had little influence on the ecological environment quality,but the influence of temperature had increased.关键词
