应用地统计学和GIS空间分析技术，对尤溪金柑主产区土壤交换性镁的空间变异特征进行了分析。结果表明，土壤交换性镁含量范围在1．05-143．19mg·kg^-1之间，平均值为48．59mg·kg^-1；半方差拟合最佳模型为指数模型，块基比为0．5，具有中等程度的空间变异，变程为4．05km；利用普通克里格插值法生成的空间分布图显示，研究区内交换性镁含量偏低，缺乏和低量区域分别为总面积的84．13％和9．84％。

The spatial variability of soil exchangeable magnesium in the major Youxi kumquat pro- duction area were analyzed by means of GIS spatial analysis and geostatistics methods. The results showed that The content ranges of soil exchangeable magnesium was 1.05 - 143.19 mg·kg-1 and the average value was 48.59 mg·kg-l. The optimum semi - variance function fitting model was Expo- nential model, the CO/CO ＋ C was 0.50, with a moderate degree of spatial variability, the range was 4.05kin. The Ordinary kriging method was used to generate spatial distribution image, which indica- ted the content of soil exchangeable magnesium was generally at a low level, of which the barren and low area accounted for 74. 11% and 8.63% of the whole study area respectively.
