陕西石质山地植被恢复的关键技术

Research on Key Technologies of Vegetation Restoration in Rocky Mountainous Areas of Shaanxi Province

陕西省石质山占地面积较大、生态系统复杂再加之地处干旱半干旱地区造林难度极大,由于历史和自然原因该地区植被破坏相当严重,水土流失问题表现地十分突出。在过去很长一段时间内虽然该地区政府机构十分重视植树造林,但树木成活率、存活率较低,植被恢复速度极其缓慢。本文通过分析陕西石质山地生态特征,探讨其植被恢复技术要点。

Rocky mountain in shaanxi province covers an area of large,complex ecological system and is located in the arid and semi-arid regions so that afforestation difficulty greatly.Due to historical and natural reasons,the vegetation damage in this area is quite serious,and the problem of soil and water loss is very prominent.For a long time in the past,although government agencies in the region attached great importance to afforestation,the survival rate of trees were low,and the speed of vegetation restoration was extremely slow.This paper discusses the key points of vegetation restoration technology by analyzing the ecological characteristics of rocky mountainous areas in Shaanxi Province.
