摘要
根据森林植被、地质地貌、水文气象、坡耕地特点将贵州喀斯特山地划分为3区10亚区16小区,并阐述了各区的相关特点;建立在树种和树种组基础上的适生模式筛选结果,将贵州喀斯特山地的退耕还林模式归为23类,可指导同区或相似区域的退耕还林模式建设。
Based on the analysis of the vegetation, geology, hyd rology, climate, and the hill farm land, the author divided Guizhou Karst upland into 3 ecoregions, 10 sub-ecoregions and 16 ecosections, with characteristic description of each. As a result, 23 species-based adaptive models were identified and to be a useful guide for the construction of the Returning farmland to Fore st Project in this area.
