Table 3 Drivers of Land Degradation.
From: Exploration of the utilization of a new land degradation index in Lake Ebinur Basin in China
Factor category | Driving factors | Independent variable | Selection basis |
|---|---|---|---|
Nature | Elevation | X1 | Altitude has a significant impact on climatic conditions, vegetation types and soil properties |
Average annual precipitation | X2 | Precipitation is one of the key climate factors | |
Average annual temperature | X3 | Affecting land degradation, and temperature changes have a direct impact on evaporation and vegetation growth | |
Soil moisture | X4 | Soil moisture is an important indicator reflecting soil moisture conditions, which affects vegetation cover and soil stability | |
Humanities | Land use | X5 | It comprehensively considers the multiple impacts of socioeconomic activities and resource utilization, and can effectively reveal how human activities drive the process of land degradation |
