摘要: 探索影响玛曲县遥感生态指数(RSEI)的主要影响因子,研究不同土地利用类型与生态质量变化之间的关系,以期为黄河流域生态保护和可持续发展提供基础数据。利用土地利用类型数据和遥感影像数据,采用RSEI对玛曲县2000—2021年生态环境质量进行综合评价,分析研究区的生态环境质量变化情况。结果表明:(1)玛曲县土地利用以草地为主,2000—2021年各土地类型变化幅度不大,2011和2017年生态环境质量出现明显下降趋势,2021年环境质量显著提高;(2)2000—2010年玛曲县生态退化面积为4484.72 km2,2011—2021年生态改善区的面积为8374.59 km²,增长了近70.05%,生态质量改善的区域明显增加;(3)2000—2021年玛曲县土地利用类型转移主要是林地与草地之间的转移。研究发现,对玛曲县生态环境质量影响最大的因子是绿度,维持植被覆盖率对于保持玛曲县生态环境质量至关重要。

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.
