广西平果县石漠化地区立地划分与生态恢复试验初报

以石漠化严重和扩展趋势明显的平果县果化镇布尧村龙何屯为例,在现有土地利用类型的基础上,综合坡度、土层厚度、裸岩率、植被盖度等因子,将该屯土地划分为8个立地类型。根据不同立地类型采取相应的生态恢复模式,设计构建不同的植物群落,生态环境治理与农村经济发展兼顾,构筑以木本农业为主的复合农林经营体系。通过两年多的综合治理,试验区农业产业结构调整、封山育林与人工诱导促进植被恢复以及生态苗圃基地建设等方面取得了初步成效。 

SITE TYPES OF THE ROCKY DESERTIFICATION AREA AND PRELIMINARY ECOLOGIC RESTORATION TEST IN PINGGUO COUNTY, GUANGXI

Taking Longhe village in Pingguo county as the research region, where rocky desertification is serious and enlarging, 8 site types are identified based on the gradient, the thickness of soils, the percentage of bare rocks and the coverage of vegetation etc. According to the condition of each site type and taking both the ecological rehabilitation of and rural economic development into account in the same time, some corresponding ecological restoration modes, building suitable plant communities and constructing woody agriculture dominated agro-forestry system, are adapted.
