The Impact of Vegetation Restoration on Soil Microbial Carbon Use Efficiency in Karst Rocky Desertification: The Driving Roles of Microbial Diversity and Nitrogen Availability
In early January 2025, the research team conducted plot layout and soil sampling along Provincial Highway 214 in Xiagang Village, located within the medium-intensity karst desertification integrated management demonstration area in Guanling-Zhenfeng County, Anshun City, Guizhou Province, China. Based on the primary specialty economic forest plantations within the study area, key vegetation restoration types were selected as experimental groups: HJ, HL, and HZ. Additionally, considering YM as a traditional cash crop in the region, YM plots were established as the control group.
