| 摘 要： | 本文以新疆库尔勒地区为例，首次运用＾１３７Ｃｓ示踪分析法对我国西部风蚀地区土壤侵蚀的强度与区域分布进行了研究，分别计算出该地区荒地，耕地，草地等土地利用类型的土壤侵蚀数平均值为５９８７．２１吨／平方公里；年，３５３７．２９吨／平方公里．年３１７１．３１吨／平方公里．年，其土壤侵蚀强度依次为荒地－耕地－草地。并据此探讨了不同土地利用类型与土地退化之间的相关关系有空间特征。

| Abstract: | The Korla area,Xinjiang Autonomous Region was selected as the case study of the wind eroded area in western China.The Caesium-137 technology was employed first time to elucidate the relationship between the land use types and land degradation. Sampling sites can be divided into three groups,including barren land,arable land and grass land.The average soil loss rates in the past 31 years for barren land,arable land and grass land are 5987.21,3537.29 and 3171.31t/km2·year respectively.It is significant to apply the new tracing technology to do some quantitative research on land degradation in the wind eroded area in China. |
