滇西北程海流域干热河谷区不同林种植物种类选择研究

程海流域地处金沙江干热河谷区,天然植被稀少,生态环境脆弱,开展植被恢复工作难度较大。为了提高程海流域干热河谷区森林覆盖率,以及生物多样性和景观多样性水平,在全面调查的基础上,文章分析了该区域自然环境特点,并从营造防护林、特殊用途林、用材林、薪炭林、经济林的角度系统论述了植物种类选择情况,最后总结了干热河谷区植被恢复及植物种类选择的要点,以期为金沙江流域干热河谷区的生态修复研究与实践提供参考。

Study on Different Forest Plant Species Selection in Dry-hot Valley Area of the Chenghai Lake Basin in Northwest Yunnan Province

The Chenghai Lake Basin is located in the dry-hot valley area of the Jinsha River.Natural vegetation is scarce and the ecological environment is fragile.It is difficult to carry out vegetation restoration.In order to improve the forest coverage,biodiversity and landscape diversity level in the dry-hot valley area of the Chenghai Lake Basin,on the basis of comprehensive investigation,this paper analyzed the natural environment characteristics of the region,and systematically discussed the selection of plant species from the perspectives of constructing shelter forest,specialpurpose forest,timber forest,firewood forest and economic forest.Finally,the main points of vegetation restoration and plant species selection in the dry-hot valley region were summarized,so as to provide reference for ecological restoration research and practice in the dry-hot valley area of the Jinsha River.
