广西喀斯特地区石漠化驱动因素分析与生态修复策略研究
Analysis of driving factors and ecological restoration strategies for rocky desertification in Guangxi karst areas:A case study of He chi city
摘要
Abstract
Rocky desertification in karst areas represents a critical ecological issue urgently requiring resolution in Southwest China,posing severe constraints on regional sustainable development.This study focuses on the karst rocky desertification area in Hechi City,the Guangxi Zhuang Autonomous Region.A risk assessment system was constructed across three dimensions-ecosystem sensitivity,exposure to human activity disturbance,and ecosystem adaptive capacity-to identify the key driving factors of rocky desertification.Utilizing ArcGIS software,multi-source scientific data were processed and analyzed spatially to reveal the spatiotemporal differentiation characteristics of rocky desertification risk and its dominant driving mechanisms in Hechi City.The results indicate that human activity disturbances(such as construction of buildings,farmlands and roads)and natural factors including soil erosion,precipitation and topography exert significant influences on rocky desertification.Therefore,the management of rocky desertification in Hechi City should adhere to the principle of integrating natural restoration with human intervention.At the level of natural recovery,this study emphasizes key technologies encompassing the optimization of native tree species selection,soil amelioration and hydrological regulation,with the aim of providing scientific foundations and practical references for ecological restoration in the karst regions of Southwest China.关键词
