摘    要:以金沙江干热河谷退化草原区为研究对象,采用不同的恢复措施及组合模式进行了植被恢复技术的研究。结果表明:不同的人工恢复措施对退化草原的植被恢复具有积极的作用。各处理总体效果表现为:围栏封育>非洲狗尾草+高羊茅+绛三叶+银合欢>非洲狗尾草+苇状羊茅+多变小冠花+白三叶>苇状羊茅+多年生黑麦草+苜蓿WL323+银合欢>猫尾草+沙打旺+多年生黑麦草+绛三叶>对照自然恢复植被。不同处理草地植物群落的多样性、物种丰富度、均匀度大小随季节的变化,以对照为最小。聚类分析将6个样地划分为4组,其中自然恢复植被(对照)被单独划分为一组,表明仍处于退化状态,当前须采取保护措施。

关 键 词:干热河谷  退化草地  生态恢复

Abstract:The study on vegetation restoration technologies with the different recover measures in the degraded grassland of arid-hot valley along the Jinshajiang River showed that all measures performed positive effect.The effect order of treatments was fence fertilizing>Setaria viridis Festuca elata Trifolium incarnatum Leucaena leucocephala>Setaria viridis Festure arundinacea Coronilla varia Trifolium repens>Festuca arundinacea Lolium perenne Medicago sativa Leucaena leucocephala>Phleum pratense Astragalus adsurgens Lolium perenne Trifolium incarnatum>control and zero fertilizing.There was positive correlation among the community diversity index,richness index and evenness index from time to space.The 6 treatments could be divided into 4 groups by cluster analysis,the control and zero fertilizing treatment was a seperate group,this indicated that the seperate control and zero fertilizing treatment was still in the degraded situation and the proper protection should be carried out.
Keywords:arid-hot valley  degraded grassland  recover measure
