青藏高原南部4种土地利用方式土壤质量评价OA北大核心CSTPCD
Evaluation of soil quality of different land use types in the southern Tibetan Plateau
为了阐明青藏高原南部土壤质量的基本特征,本研究采集了该地区4种典型土地利用类型(草地、耕地、乔木林地和灌木林地)的土壤样品,测定土壤相关理化指标,利用主成分分析法筛选最小数据集指标,并运用土壤质量指数法(SQI)定量评估土壤质量.结果表明:土地利用方式对土壤理化性质具有显著影响,饱和导水率属于极敏感指标,电导率、全氮、有机质、砂粒属于高度敏感指标,pH、容重、粉粒、黏粒属于中度敏感指标.青藏高原南部土壤质量评价最小数据集由全氮、粉粒、黏粒、电导率…查看全部>>
In order to clarify the basic characteristics of soil quality in the southern Tibetan Plateau,we collected soil samples from four typical land use types(grassland,plowland,woodland,and shrubland)in this region,measured the relevant basic physicochemical indicators of soil,screened the minimum data set indicators using principal component analysis,and applied the soil quality index(SQI)method to quantitatively evaluate soil quality.The results showed that the…查看全部>>
