摘要为找到一种黄土区不同地类景观功能的综合评价方法,在蔡家川流域利用LFA方法(Landscape Function A-nalysis)对10种地类150块样地进行了调查、评价,共布设样线4 400多m。结果表明:LFA方法能够应用于植被斑块作用和样地土壤性能的评价;基于该方法,通过加权求和得到的景观功能值,能够综合反映植被斑块作用的大小和样地土壤性能的优劣;土地利用类型和坡度对景观功能有显著影响。通过多元线性回归,引入土地利用类型和坡度这2个变量能够得到计算样地景观功能值的方程,且所得回归方程结构较合理,计算精度较高,可以用于黄土区不同地类景观功能的综合评价。
Abstract：For studying a comprehensive evaluation method of landscape function for different land-use types in Loess region,we investigated and evaluated 150 plots by LFA method(Landscape Function Analysis)in Caijiachuan Basin,laid a total of more than 4400 meters transects.The results showed that: LFA method can be used to evaluate the effect of vegetation patches and soil properties of plots;based on LFA method,with weighted sum,the value of landscape function can reflect the effect of vegetation patches and soil properties of plots comprehensively;land-use types and slope have a significant influence on landscape function,and a calculation equation of landscape function value was established.The conclusions are as following: the multiple linear regression equation has reasonable structure and relatively high accuracy,which can be used to evaluate landscape function for different land-use types comprehensively.
