中文摘要: |
本文对北京通州辖区范围内组织的大规模的土壤墒情调查数据进行总结。基于地理统计、空间分析以及统计学知识,分析了北京通州旱情分布形势。运用数值分类学的知识对测量数据进行了聚类分析,同时用DB(Davies-Bouldin)指标准则研究了区域内合理布设旱情监测站的数量及位置,为建立旱情监测站点提供了理论依据。 |
英文摘要: |
On the basis of geostatistics and principle of spatial analysis the map of soil moisture content distribution in Tongzhou District, Beijing, is established by using GIS. The soil moisture data are analyzed by clustering method and the reasonable arrangement of stations for draught monitoring, including the amount and locations, are determined by means of Davies-Bouldin index criterion. The result can be displayed on GIS. |
