中国西南岩溶区石漠化严重,呈加剧趋势,危害很大,不但导致生态退化、水土流失、自然灾害频繁,而且影响人类的生存,成为我国最严重的生态环境问题之一。喀斯特峰丛区是治理难度最大的地区之一,选择广西平果县龙何屯峰丛区为示范点,以生态学原理为指导,优化土地利用结构,调整农村产业模式,生物工程、水利工程结合,提倡复合农林经营,选择优良乡土树种,模拟天然植被构建先锋植物群落,针对生境异质性的主导因子,强化岩溶山地造林与封育管理技术,开发特有适生的名特优产品,实行乔灌藤草优化配置、生态防护林体系与特色农林产品基地建设结合,经过3年的示范试验,植被覆盖率由10%提高到37%,农民人均收入增长20%。
Rocky desertification in southwest China’s karst region is serious and aggravating. It not only leads to ecological degradation, soil erosion and natural disasters, but also affects human survival. It has become one of the most serious ecological and environmental problems in China. Karst peak cluster is one of the most difficult areas for management. Taking Fengtong County, Pingguo County, Hunan Province as an example, taking ecological principles as guidance, optimizing the structure of land use, adjusting rural industrial mode, bioengineering, water conservancy project Combine and advocate composite agroforestry, select excellent native tree species, and simulate natural vegetation to build a pioneer plant community. In response to the dominant factor of habitat heterogeneity, strengthen the management of karst mountain afforestation and enclosure management, develop unique and well-known name-superior products, implement After three years of demonstration experiments, the vegetation coverage rate has been increased from 10% to 37%. The per capita income of farmers has increased by 20%.
