摘要
广西石漠化生态环境治理与科技扶贫是我国治理石漠化重点和难点,围绕广西喀斯特地形石漠化侵蚀过程,研究分析石漠化地区植被—土壤耦合规律与气候因子的相关性,阐述了广西喀斯特地区生态系统退化机制。通过分析树种选用、饲用植物、苔藓植物、木本油料植物以及山地混林生态修复模式,探索广西喀斯特地区石漠化植被生态修复技术,为促进广西喀斯特地区石漠化生态文明建设与区域经济发展提供技术支撑。
The ecological environment control of rocky desertification in Guangxi and the poverty alleviation of science and technology are the key and difficult points in the treatment of rocky desertification in China.In this paper,the study on the erosion process of rocky desertification in Karst,Guangxi,analyses the correlation between the vegetation soil coupling law and the climate factors in the rocky desertification area,and expounds the ecological system degradation mechanism in the Karst area of Guangxi.By analyzing the selection of tree species,forage plants,bryophytes,woody oil plants and ecological restoration patterns of mountain mixed forest,the ecological restoration technology of rocky desertification vegetation in Karst area of Guangxi is explored to provide technical supports for promoting the ecological civilization construction and regional economic development of rocky desertification in Karst area of Guangxi.
