以乌鲁木齐市北郊蔬菜基地为典型区甜干旱区绿洲城市郊区土壤有效态镍含量的结构特征进行分析，得出该区有效态镍的空间分布格局并揭示了引起这种分布格局的成因，结果表明：乌鲁木齐市北郊蔬菜基地有效态镍属中等变异。半方差函数模型拟合表明有效态镍含量可以用球状函数拟合，具有高度的空间自相性，有效态Ni主要受内在因子（土壤形成因子，如气候、地形、土壤类型等）控制。采用Kriging最优内插法得到了有效态镍含量的空间分布格局，呈现明显的北高南低分布规律。

This article analyses on structural features of soil active nickel in oasis select Urumqi Northern suburb vegetable base as a typical area and sums up the suburb of aridity region, which spatial distribution pattern of active nickel in that area and reveals the causes of the distribution pattern. The results show that: the active nickel in Urumqi Northern suburb vegetable base is a moderate variability. Semi -variogram model fitting shows that active nickel can be fitted with a spherical function, having a high degree of spatial autocorrelation. The active nickel is mainly controlled by intrinsic factors (soil formation factors, such as climate, topography, soil type, etc. ). Getting spatial distribution pattern of active nickel content by Kriging, the distrabution is obviously high in the north and low south.
