摘　　要：通过现场调查和样方调查法,分别调查衡阳市紫色岩半裸露地区的地形、地貌、气候、母岩、土壤等因子以及不同立地条件下的植物搭配、植被种类、植被覆盖度、生长状况,并采用对比研究法,进行品种及其模式的配置试验,评价不同植物品种适应性与不同搭配模式植物种群的适应性及保水、保土能力,最终筛选出不同立地条件下适宜的植物与植物配置模式,为紫色岩地区造林提供理论依据。The factors of site conditions representing landform, climate, parent rock, soil were surveyed by filed investigation, and vegetation types, vegetation composition, coverage and growth were measured by using quadrat sampling method, and the species and arrangement model were tested. And finally, the suitable species and its arrangement patterns were determined based on the appraisement of suitability and soil and water conservation benefits of different species suitability and arrangement patterns.
