| 摘 要： | 运用地统计学,结合GIS技术研究了20年来广东省新会地区土壤全钾和有效磷的时空变异规律.结果表明,研究区域耕地土壤由于20年来的耕作施肥使得土壤全钾和有效磷含量显著增加,土壤全钾在研究区域的南部变化最明显,与该地区的土壤类型为咸田有很大关系;耕地土壤全钾和有效磷的空间分布都表现为中等空间相关性;土壤全钾和有效磷变程的变化与土壤养分在土壤中化学行为有关.

| Abstract: | Geostatistical methods were used in combination of GIS to analyze the spatial distribution char- acteristics of total K and available P in cultivated soils in Xinhui district, Guangdong Province, over 20 years from 1982 to 2003. The results showed that the content of total K and available P significantly increased with the cultivation and fertilizer application in the past 20 years; the content of total K in the south significantly increased; the total K and available P in cultivated soils had moderate spatial relativity ; the range of the total K and available P had relationships with the chemical action of soil nutrients. |
