祁连山地处青藏高原东北部,是东亚季风和西风带的过渡区域,对全球气候变化极其敏感。深入理解祁连山典型森林生态系统土壤养分的空间格局,对于祁连山森林资源的保护及构建我国西部生态安全屏障具有重要意义。本报告从祁连山青海云杉林土壤养分空间变化的视角出发,系统梳理了以往对该区域土壤养分特征的研究成果,并结合笔者现有的研究资料和数据,试图认识祁连山区域土壤养分的空间分布规律,以期为祁连山区域森林生态系统的恢复、森林的培育、林业资源的管理及保护提供科学依据;并提出通过实施合理的植树造林、休牧轮牧、改变产业结构和加大环境执法力度等措施来保持与修复祁连山区域土地养分生产力的对策建议。
<<The Qilian Mountain,located in the northeastern part of the Qinghai-Tibet Plateau,is a transitional region between the East Asian monsoon and westerly zones and extremely sensitive to global climate changes. An in-depth understanding of the spatial pattern of soil nutrients in typical forest ecosystem of the Qilian Mountain is of great significance for the conservation of forest resources in the Qilian Mountain and the construction of ecological security barriers in western China. From the perspective of spatial changes to soil nutrients in Qinghai spruce forests of the Qilian Mountain,this report systematically sorts out previous research results on soil nutrient characteristics of the region,and utilizes available research information and data to understand the spatial distribution patterns of soil nutrients in the Qilian Mountain region,for the purpose of providing a scientific basis for restoration of forest ecosystem,cultivation of forests,and management and protection of forest resources in the Qilian Mountain region. It also proposes countermeasures to maintain and restore the nutrient productivity of the Qilian Mountain region by implementing reasonable afforestation,grazing rest and rotation,changing industrial structure,enhancing environmental law enforcement,etc.
