Study on Cu content in cultivated soils and its influence factors in Guangxi;

广西耕地土壤铜的含量及其影响因素

Geostatistical methods were used in combination of GIS to analyze the spatial distribution characteristics of total K and available P in cultivated soils in Xinhui district,Guangdong Province,over 20 years from 1982 to 2003.

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。

In this project, analytical data of 20 items from 367 of cultivated soil samples in Minhou county were selected, and principle component and gray relation analysis methods were used for revealing the relationship between soil properties and environmental factors.

耕地土壤性质与气候、地形、母质等自然环境和人类活动存在错综复杂的内在联系 。
