【摘要】 本文在干热河谷植被恢复过程中的"适度"造林技术提出的基础上,以干热河谷的自然植被演替、土壤水分承载力、立地异质性为依据,从系统化、定量化的研究角度,在林分结构(微观)上探讨了造林"适度"密度,在区域景观尺度(宏观)上探讨植被恢复的群落"适度"配置,旨在进一步阐明"适度"造林技术与理论,以期为干热河谷植被恢复的研究与实践提供参考。更多还原

【Abstract】 In this paper,on the basis of the"moderate"afforestation technology proposed in the process of vegetation restoration in the dry hot valley,and according to the natural vegetation succession,soil water carrying capacity and site heterogeneity,discussion was made on the"moderation"density of afforestation in stand structure and the"moderation"community allocation of vegetation restoration on the regional landscape scale from the perspective of systematic and quantitative research. The "moderation"afforestation techniques and theories were further illustrated in order to provide reference for research and practice of vegetation restoration in the dry hot valley.更多还原
