摘要

喀斯特石漠化现象已成为制约农村社会经济发展的严重障碍

其生态治理已成为学术界的研究热点和地方政府的迫切任务。以贵州省花江石漠化生态治理示范区人工植被为研究对象

对人工植被的结构与物种多样性进行研究。结果得出

示范区以花椒为主的人工植被的物种配置和空间结构都比较合理

其物种多样性与群落结构有着密切关系

随均匀度增大而增加

随生态优势度的增加而递减

并随石漠化强度的加重及海拔的升高而增加;认为只要人工林模式的结构配置得当

管理配套

石漠化完全可以兼顾生态—经济效益进行治理。

Abstract

The phenomenon of rocky desertification presents a serious obstacle to rural economic development.Control of rocky desertification is drawing increasing academic attention and is an increasing urgent problem for local government.This study focused on the appropriate st ructure and species diversity of artificial vegetation in rocky desertification areas

established as a means of control. It was concluded that artificial vegetation with a spatial structure and species disposition dominated by pricklyash peel is suitable for desertification control

and that this assemblage has an advantageous community structure

which develops uniformly and with ecological dominance

which increases with latitude and as the rocky desertification process identities. It is proposed that rocky desertification areas can be managed

with ecological and economic benefits

with the establishment and management if such well st ructured artificial vegetation.
