摘　　要：衡阳地区是湖南省紫色土区的主要分布区之一,植被稀疏而贫乏。该紫色土区的自然环境主要有两大特点:年降水量虽大,但蒸发量更大;土壤瘠薄,基岩裸露,水土流失严重。基于此,提出应划分适宜的生态植被恢复区域,根据原生演替规律,选定适宜于紫色土区植被生态恢复模式和技术措施等对策,使紫色土区植被"短、平、快"地恢复。Hengyang area is one of the main distributive regions of the purple soil in Hunan province, Based on the investigation, this paper makes research on it natural environment characteristics. Furthermore it analyzes that the its ecological vegetation rehabilitation models and conservation technical measures so as to make the purple soil vegetation restore peacefully and quickly in a short period.
