云南南涧干热退化山地水分调蓄与植被恢复途径的试验研究

在云南南涧后山开展的以生物生态工程为主治理泥石流的研究中,围绕着干热退化山地水分调蓄与植被恢复的问题,我们于１９９０－１９９３年期间,从适生物种筛选、整地方式选择、种植技术与管理、生物篱与生物谷坊的结构和组合,以及调蓄水系统建设等方面进行了试验研究,取得了较好的效果,为该地区退化山地生态系统的恢复重建奠定了良好的基础。根据试验结果和治理区的自然生态环境现状,我们认为,以调蓄水系统为核心的综合生物治理措施是干热退化山地生态系统恢复重建中最有效的治理途径之一。

EXPERIMENTAL STUDIES ON WAYS OF WATER STORAGE AND VEGETAION RESTORATION IN DRY-HOT DEGENERATIVE MOUNTAINOUS AREA IN NANJIAN,YUNNAN

In the years from 1990 to 1993, we carried out the experimental studies of suitable species selection, land preparation mode, planting technique and management,structure and combination of biological hedge and biological check dam as well as reservioring water system construction in the dry-hot degenerative mountainous area in Nanjian,Yunnan. The results showed that regulating and controlling water was the most important problem in the bioecological project for controlling the debris flow. On the basis of the experimental results and the analysis of the environmental conditions, we consider that the comprehensive biological control which takes the water storage system as the key is the most effective way for restoring the ecosystem in the dry-hot degenerative mountainous area.
