土壤是人类赖以生存的最基本的自然资源之一,是岩石圈表面的疏松表层,是陆生生物生活的基质,是维系陆地生态系统食物链的一个重要环节1].

Soil Environment Quality Assessment of Forest Landwith Different Parent Mater ia ls in Ka sta Mounta in Area

The soil environment quality of woodland with different parent materials(limestone,dolomite limestone,limestone shale,dolomite,limestone sand inclusion shale) in Kasta mountain area was assessed with Analytic Hierarchy Process and Principal Component Analysis methods.The results indicated that the soil fertility quality of the soil developed from limestone shale was the best,and the soil developed from dolomite limestone was the worst.The soil developed from limestone shale showed the best heavy metals quality,and the soil developed from dolomite was the worst.The soil developed from limestone shale had the best stand condition quality,and the soil developed from limestone sand inclusion shale was the worst.The results also showed that the order of the soil environment quality was: limestone shale>limestone>dolomite limestone>dolomite>limestone sand inclusion shale.
