摘要
以2006年森林资源二类调查数据为信息源,在ArcView支持下,把西山森林公园划分为14种景观类型,并建立了由8个景观指数组成的稳定性评价指标体系,利用ArcView扩展模块Patch Analyst定量计算景观指标值,建立景观指标标准化矩阵,并运用主成分分析法,构造森林景观稳定性综合评价模型,对西山森林公园各景观类型的稳定性进行了评价与分析。结果表明:西山国家森林公园森林景观稳定性依次为:华山松—桃—苹果—栎类—杜鹃—柏木—竹—云南松—马桑—苦刺—其他阔—蓝桉—圣诞树—桤木。该结果可为西山公园森林景观经营管理提供技术支撑。
Based on class II investigation on forest resources in 2006,with the help of ArcView,14 landscape types were assorted in Xishan Forest Park of Kunming. The index system for evaluating its forest landscape stability was designed and 8 forest landscape stability indices were selected. And a standard matrix of landscape indices was established. A synthetic evaluation model for forest landscape stability was established with Patch Analyst tool of ArcView. By using principal component analysis in SPSS,the factors influencing Xishan Forest Park Forest Landscape stability were analyzed. It proved that there are great differences among those landscape types in stability. The values of stability go from high to low as follows：Pinus armandii-Peach-Malus pumila Mill.-Robur-Cuckoo-Cypress-Bamboo-Pinus yunnanensis Franch-Coriaria sinica Maxim.-Solanum deflexicarpum-Broad-leaved forest-Eucalyptus globulus-Christmas tree-Alnus cremastogyne. It provides a scientific basis for sustainable management to Xishan Forest Park of Kunming.
