| 摘 要： | 在哈尔滨市辖区的6个市县采集了黑土表层(0~20cm)土样411个,测试了有机质、全氮的含量,利用经典统计学和地统计学结合GIS分析了两种养分的空间异质性,分析表明有机质和全氮的理论模型均为指数模型,其块金值和基台值之比分别为0.597和0.520,都为中等程度空间相关;利用地理信息系统软件和地统计学软件相结合绘制出养分空间分布图,为该区农业规划、生产管理、合理布局提供了科学依据。图5,表2,参10。

| Abstract: | The soil organic matter(SOM) and total nitrogen(TN) were analyzed from the samples collected at 6 areas in Harbin.The results showed the there was a significant correlation between SOM and TN.The spatial variability of soil nutrients were analyzed with Classical statistics and geostatistics combined with GIS.The results showed that the semivariogram of organic matter and total nitrogen was best described by Exponential,the ratios of nugget to sill of organic matter and total nitrogen were 59.7 % and 52%,respectively,indicating that the spatial autocorrelation of the two nutrients indices were moderately dependent. The maps of the two kinds of nutrients distribution were drawn by GS and GIS to provide scientific basis for agricultural design,production management and reasonable implement. |
