基于SA-RSEI模型的盐池县生态质量演变研究

doi:10.13866/j.azr.2024.06.13

Abstract

Abstract:

This study explored the characteristics and driving factors of the dynamic spatio-temporal changes in the ecology and environment in Yanchi County by using remote sensing images from 1990 to 2020 as the data source and the SA-RSEI as a basis. By combining the Theil-Sen Median analysis, Mann-Kendall significance test, and Hurst index, the pattern of spatiotemporal variations in the ecological and environmental quality of Yanchi County was analyzed. The driving factors of this quality were explored by employing the Geography Detector. The results showed that (1) SA-RSEI initially reduced and then enhanced from 2000 to 2020. (2) The ecological and environmental quality showed an evolutionary process of “initial degradation and then recovery” during these 21 years. The spatial distribution pattern gradually changed from “poor in the south and good in the north” to “good in the southeast and poor in the northwest.” (3) During the 21 years, the ecological and environmental quality of Yanchi County generally degraded, but the degree of degradation gradually reduced, and the degree of ecological and environmental improvement gradually increased after 2020. (4) DI, precipitation, elevation, and GDP are the main factors influencing the spatial variation in regional ecological quality. (5) The interaction between DI, temperature, precipitation, elevation, and other detection factors plays a leading role; the influence of economic factors on SA-RSEI gradually enhances.

Key words: ecological quality, improve the ecological index, geographical detector, Hurst index, Yanchi County
