| 摘 要： | 以内蒙古赤峰市敖汉旗大五家流域内林草植被为研究对象,从林冠层、枯落物层、土壤层和林分生产力等方面选择评价指标,通过层次分析法确定评价指标的权重,应用主成份分析方法对不同林草植被涵养水源功能进行综合评价。旨在评价不同林草植被类型水源涵养功能的差异,为探寻低功能涵养水源型林草植被更新改造途径提供依据。研究结果表明:华北落叶松白榆混交类型涵养水源功能较高,其次是杨树柠条混交类型,油松沙棘混交类型涵养水源功能最差,在该流域应提倡营造针阔混交林。

| Abstract: | The forest and grass vegetation types in Dawujia watershed of Ao'han County,Chifeng city were taken as the research object.Eva1uation indexes were determined from forest canopy layer,litter layer,soil layer and productive forces et al,and comprehensive evaluation were carried out by the analytic hierarchy process and principal component analysis method to evaluate the differences of water conservation function of the forest and grass vegetation typese,and to inquire about renewal transformation ways of the ... |
