Popularization of ecological reconstruction technology in peak-cluster depression of Guangxi

The ecological reconstruction model and technology of peak-cluster depression studied in this book are suitable for most peak-cluster depressions in Guangxi, but there are differences in ecological environment fragility, rocky desertification area, population density and economic situation among 24 key peak-cluster depression counties. In the concrete implementation, there should be some differences in the choice of mode and the arrangement of governance intensity. In low-lying areas with low population density, priority should be given to local ecological management and three-dimensional ecological agriculture model should be chosen. In areas where the population density exceeds 150 people /km2, some ecological migrants should be the main ones. The areas that need emergency treatment and ecological reconstruction should first be areas with serious or extremely fragile ecology, mainly including Du 'an County, Dahua County, mashan county County, Jingxi County, Nandan County, Xincheng County, Pingguo County, Tiandeng County, Donglan County, lingyun county County, Fengshan County, Bama County and Huanjiang County in Guangxi (Table 78).
