耕地分布及其扩张过程与土壤类型空间相关分析

Correlation Analysis on the Arable Land Distribution and Changes

在遥感和地理信息系统支持下,分析了黑龙江省大庆市杜尔伯特蒙古族自治县耕地分布与土壤类型之间的相关关系;20世纪50年代以来耕地扩张过程与以土壤为主的土地质量之间的空间相关关系。结果表明该区耕地分布与土壤类型关系密切,主要分布在黑钙土、草甸土和砂土分布区;耕地扩张过程与土地质量空间相关关系密切,其联合熵达0.790。

The correlation between arable land distribution and soil types in D. M. County and the spacial correlation between the course of arable land expansion and the soil quality since 1950s were analyzed. The results showed that the soil distribution had a remarkable correlation with the soil types （ cheronozem, meadow soil and sand earth）. The correlation between arable land expansion and soil quality was verv close and the combine entropy was 0. 790.
