论岩溶峰丛洼地石漠化的综合治理技术——以广西平果果化示范区为例

广西平果县果化生态重建示范区面积600hm^2，为典型岩溶峰丛洼地，居民贫困、石漠化严重。2001年以来，通过详细调查研究，因地制宜建立了适合峰丛洼地地貌结构特点的复合型立体生态农业模式:开发20多种乡土树种，人工诱导封山育林310hm^2，开发表层岩溶泉、岩溶天窗和隐伏岩溶管道水资源每年1万多立方米，引进了多种优质高效果树和药材，培植了生态产业，在土地整理的基础上，采用综合措施对岩溶土壤进行了改良，在开发引进多种适宜优质牧草的基础上发展家庭养殖业，提高了生态和农业生产的效果和效率，不但石漠化得到治理，峰丛洼地生态逐步恢复，而且农民纯收入年均增加20％，促进了区域经济的发展。 

Comprehensive improving technique to rocky desertification in karst peak-cluster depression -A case study at Guohua Ecological Experimental Area,Pingguo, Guangxi

With typical karst peak-cluster depression landform,poor people and heavy rocky desertification, Guohua Ecological Experimental Area in Pingguo county, Guangxi is about 600 hm^2. Since 2001, the Eco- logical Experimental Area has been built. After investigation and researches to the environments and regional economics in detail, the stereo eco-agricuhure in different geomorphologic position of the peak-cluster depression is considered as an available model for the comprehensive improvement to rocky desertification. Meanwhile, a lot of related technique and methods for the improvement of environments and the development of agriculture are imported, studied and put into practice, such as forestation of 310 hm^2 hills, exploitation of more than 10 000 m^3/a karst water resource, development of ecological industry, planting of grassland for breeding of domestic animals, and improvement of karst soils. For about four years, the comprehensive improvement of rocky desertification in the experimental area has achieved good results. The vegetation is grad- ually restored, the annual mean income of the local people has increased by about 20%, and the new local ecological industry is formed.
