Balancing the Effects of Forest Conservation and Restoration on South China Karst Greening

A study reveals that forest conservation and restoration have significantly contributed to vegetation greening in South China Karst, with conservation accounting for 39.85% of the increase compared to just 6.05% from restoration. The research, spanning 2000–2020, analyzed land use data, forest cover loss, and Leaf Area Index (LAI) using Moderate Resolution Imaging Spectroradiometer (MODIS) data. It found a nonlinear, inverted U-shaped relationship between conservation and restoration effects across provinces, suggesting that balancing both strategies is crucial for effective ecological engineering. This finding provides a scientific basis for differentiated planning to optimize greening outcomes in karst regions.
