| 摘 要： | 通过长期历史数据的积累并结合空间数据,组建黑龙江省土壤养分GIS系统。在该系统的基础上利用常规统计学和地统计学的方法时黑龙江省黑土区土壤有机质进行了分析。分析表明,自第2次土壤普查以来,黑龙江省黑土区25个市县土壤有机质分别下降了1．43％～4．12％,平均每年下降0．06％～1．48％。以GIS为工作平台利用地统计学等先进方法分析区城土壤养分的空间分异特征时精准施肥、保护生态环境和优化农业生产管理有着重要的意义。图3,表1,参9。 |

| Abstract: | GIS system of soil nutrient was established in Heilongjiang province based on large data collections,and than soil organic content was analyzed by using classical statistics and geostatistics method.The analysis indicated the soil organic content in 25 counties decreased among 1.43%-34.12% in average since 1980,which means decreasing 0.06%-1.48% per year.GIS will be a very useful working platform for spatial variability analysis of soil nutrients and precision agriculture and sustainability agricultural ecology. |
