摘要采用LFA(Landscape Function Analysis)方法,通过调查7种地类35组样本,评价植被类型、人类活动对林地景观功能和土壤性能的影响,并验证LFA方法在黄土区的适用性。结果表明:不同植被类型对林地土壤结构稳定性、渗透性能、养分循环性能的影响显著,其中,天然次生林改良土壤结构稳定性、渗透性和养分循环性能的作用最好,其次是刺槐人工林、油松人工林,荒草坡最差;人类活动对人工林地景观功能和林地土壤结构稳定性有显著影响;LFA方法能够较好地评价植被类型对林地土壤性能的影响,以及人类活动对人工林地景观功能和林地土壤结构稳定性的影响,在黄土残塬沟壑区有较好的适用性。
Abstract：Based on the LFA(Landscape Function Analysis) method,35 samples of 7 land types and the effects of the vegetation type and human activity on forest landscape function and soil properties were evaluated.The results show that the affects of different vegetation type on soil properties are distinctly different.The soil properties(structure stability,infiltration,nutrients cycle) of natural secondary forest are the best;that of Robinia pseudoacacia and Pinus tabulaeformis plantation are second;that of grassland is the worst.Human activity has obvious affection on landscape function of plantation.The affection of vegetation on forest soil properties and the affection of human activity on forest landscape function and soil structure stability can be evaluated by LFA.
