项目摘要

Soil samples were collected from arable land in Asia (Thailand, Malaysia, India, Cambodia, Sri Lanka, Bangladesh, Philippines, Indonesia, Vietnam, Burma and East Malaysia), South America (Parguay, Brazil and Columbia) and Africa (Nigeria, Ivory Coast, Sierra Leone, Liberia, Zaire and Rwanda) and analyzed for mineralogical and physico-chemical characterization.Multivariate statistical analysis (principal component analysis) was applied to the above mentioned soils data and three factors controlling soil fertility, i.e.inherent potentiality, organic matter status and available phosphorus status were extracted, each of these enabling quantitative soil evaluation. The same procedure was applied to those samples and two factors, i.e.Iithology and weathering status, were identified and proved to be useful for characterizing the nature of soil materials. All such factors were closely related to the type of predominating clay minerals of each soil.
土壤样品是从亚洲的可耕地上采集的(泰国、马来西亚、印度、柬埔寨、斯里兰卡、孟加拉国、菲律宾、印度尼西亚、越南、缅甸和东马来西亚)、南美洲(帕尔盖、巴西和哥伦比亚)和非洲(尼日利亚、象牙海岸、塞拉利昂、利比里亚、扎伊尔和卢旺达),并分析矿物学和物理化学特征。对上述土壤数据进行主成分分析,提取出控制土壤肥力的三个因素,即固有潜力、有机质状况和有效磷状况,每一个因素都可以对土壤进行定量评价。同样的程序适用于这些样品和两个因素,即岩性和风化状态,被确定和证明是有用的表征土壤材料的性质。这些因素与土壤中主要粘粒矿物类型密切相关。
