文章以赤峰市敖汉旗大五家小流域内的人工防护林——选择小流域内的典型林地,分别是小叶杨纯林、油松纯林、小叶杨柠条混交林、油松沙棘混交林和柠条纯林为研究对象,利用GIS应用软件得到流域内防护林空间格局,运用主成分分析法对不同坡度和不同坡向下的典型林地土壤质量状况进行了综合评价,探讨了小流域典型林地合理的空间配置,旨在为该地区的人工生态林的营造和管理提供基础性的指导。
Artificial shelterbelts in five small watersheds in Aohan Banner, Chifeng city were selected as the typical forest land in small watershed, including Pure Betula platyphylla, Pure Pinus tabulaeformis, Mixed Populus simonii Mixed Forest, Pinus tabulaeformis Mixed Mixed Forest, The pure forest was taken as the research object. The spatial pattern of shelterbelt in the basin was obtained by using GIS software. The main soil component analysis method was used to evaluate the soil quality of the typical forest land with different slope and slope. The spatial configuration aims at providing basic guidance for the creation and management of the artificial ecological forest in this area.
