Abstract:

To objectively evaluate the impact of driving factors on the ecological environment quality of Tumshuk City, Xinjiang, China, this study selects Landsat image data from three periods, 2000, 2011, and 2021. This data was coupled with normalized difference vegetation index, soil moisture, dryness index, and land surface temperature indicators. It analyzed principal components to construct a remote sensing ecology index (RSEI), combined natural and socioeconomic factors in the study area, and dynamically monitored and evaluated the ecological environment quality of Tumshuk City in the past 22 years. The results showed the following: (1) In the past 22 years, the average RSEI of Tumshuk City increased from 0.406 to 0.476, and the area with improved ecological environment quality was far greater in size than the area with deterioration. The improved areas were mainly distributed in the study area's central, southeast, and northwest regions, and their ecological environment quality has been effectively improved in the past 22 years. (2) By analyzing the driving factors of Tumshuk City, it was observed that the local ecological environment quality was influenced by factors such as population, gross domestic product, arable land area, and climate. Among the driving factors, socioeconomic factors had a notable impact on the local ecological environment quality. (3) By constructing RSEI and analyzing its driving factors on the impact of ecological environment quality, dynamic monitoring and objective evaluation of local ecological environment quality can be efficiently and accurately conducted.

Key words: Tumshuk City, remote sensing ecology index, ecological environment quality, driving factors, dynamic monitor
