| 摘 要： | 文章采用地统计学中半方差函数,研究了库布其沙漠白刺种群的空间格局。在杭锦旗北部设置一个1000×1000(m)的样方,将样方划分为25×25(m)的格子,记录各格子内出现的物种及其平均冠幅。运用地统计软件GS+for Windows计算样地各白刺种群的各向同性半方差函数的参数,并绘制其克立格(Kriging)图。从半方差模型的参数来看,白刺(Nitraria tangtorum)属于聚集性分布的指数模型,其空间结构比率低。

| Abstract: | In this paper,the spatial pattern for Nitraria tangtorum in Kubuqi Desert,Inner Mongolia was studied by using the semivariogram in Geostatistics.A sample plot with 1000×1000(m),which was divided in to 25×25(m) grids,was set in north of Hangjinqi.The species and mean crown width in each grid were investigated and recorded.Using the software GS+ for Windows,the parameters of the semivariogram were calculated.The spatial distributions for Nitraria tangtorum,follow the exponential model of cluster distribution. |
