昆明地区红壤中Be-7分布研究
Distribution of Be-7 in Red Soil of Kunming Area
摘要
Abstract
[Objective] The research about the distribution and the content of Be-7 in red soil is important for tracing soil erosion rate,which could provide important reference for soil conservation and environmental protection. [ Method The Be-7 profile distribution and the areal activity density in different types of land use in red soil, Kunming area were studied with Be-7 tracer technology. [ Result ] Be-7 was distributed in the sur- fuce soil of 0 -20 mm in depth. The higher Be-7 content was mainly distributed in 0 -4 and 6-12 mm in depth. There were lots of difference a- bout the distributions of Be-7 content among different types of land use,such as flood plain,wild grass ground,cultivated land,forest land and so on. And Be-7 profile distributions in different types of land use were different. [Conclusion] Distribution of Be-7 was related to land vegetation coverage, soil texture and mechanical composition and so on.关键词
