Temporal-spatio Changes of Vegetation Cover and Its Relationship with Terrain Factors in Jinzhai County

By monitoring and studying changes in vegetation coverage, we can assess the stability and biodiversity of ecosystems, and promptly identify changes and issues in the ecological environment. This study was based on Landsat data and selects data from 2003 to 2023, including 2003, 2007, 2011, 120, 152, 2019, and 2023.The pixel binary model was used to calculate the vegetation coverage of Jinzhai County for the past 20 years and 6 periods. Combining trend analysis to study the temporal-spatio changes characteristics of vegetation cover in Jinzhai County. Combining DEM data and distribution index methods to explore the relationship between vegetation coverage and terrain factors. Results showed that: (1) The vegetation cover in Jinzhai County showed an overall increasing trend, mainly with MH-FVC and H-FVC. (2) The vegetation coverage was closely related to terrain factors. With the continuous increase of elevation and slope, the vegetation coverage in Jinzhai County continues to increase.
