摘  要：
以西藏拉萨河流域曲水一带农用地为例,应用地统计学分析方法对研究区土壤锗空间分布进行了变异函数的计算和模型拟合,基于最适空间插值理论模型运用克里金方法进行了土壤锗空间插值分析。结果表明:研究区土壤锗均值为1.265 mgkg-1,有效锗均值为0.0128 mg kg-1,均以聂当乡一带含量最高;研究区土壤锗变异系数表现为弱变异性、有效锗表现为中等变异性,说明研究区土壤锗、有效锗含量受人为活动影响较小;研究区土壤富锗情况较好,大部分农用土壤具有富锗特征(≥1.3 mg kg-1),其中以柳梧乡、聂当乡、才纳乡一带该类土壤为最多,富锗土壤面积约50.9 km2。研究区具有富锗农产品生产的基础条件,具有富锗农牧业发展优势。

摘  要：
The variogram and model fitting of soil germanium(Ge) spatial distribution in the farmland of the Qushui area, Lhasa River Basin, Tibet were carried out by using the geostatistical analysis method. Based on the optimal spatial interpolation theory model, Kriging method was used to carry out the spatial interpolation analysis of soil Ge.The results showed that the distribution of soil Ge in the research district was homogeneous. The average concentration of total Ge was 1.265 mg kg-1 and that of effective Ge was 0.0128 mg kg-1, with the highest in Niedang. The total Gein soils howed a weak variability and the effective Ge showed a medium variability, which indicated that the concentration of soil Ge and effective Ge in the research district was less affected by human activities. The soil Ge was rich in the research district, especially inagricultural soils( ≥1.3 mg kg-1) of Liuwu, Niedang and Caina. The area of soil Gerich was about 50.9 km2. The research district has the basic conditions for the production of Ge-rich agricultural products and the advantages of Ge-rich agricultural and animal husbandry development.
