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模数的平均值为5987．21吨／平方公里·年、3537．29吨／平方公里·年和317131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及空间特征。这对于丰富风蚀地区土地退化研究的理论和方法，制订准确的土地退化防治对策，进一步合理利用土地资源具有理论和实践意义。
Taking the Korla region in Xinjiang as an example, 137Cs tracer method was used for the first time to study the intensity and regional distribution of soil erosion in western China. The soil erosion models The average values of soil erosion were 5987.21 t / km 2 · year, 3537.29 t / km · · year and 317131 t / km 2 · year, respectively. Based on this, the correlation and spatial characteristics of different types of land use and land degradation are discussed. This is of theoretical and practical significance for enriching theories and methods of land degradation in wind-eroded areas, formulating accurate countermeasures for prevention and control of land degradation and further rational utilization of land resources.
