Abstract

The aim of this study was to determine the relationship between land exploitation and soil salt accumulation in the topsoil. A typical desert-oasis ecotone, the Fubei region at the lower reach of the Sangong River catchment in arid northwest China, was used as a case study. The results revealed that : 38% of the studied area experienced transitional land-use changes; Soil salt accumulation per unit area increased by 60%; Salt accumulation resulted from increased irrigation as more land transitioned to farmland. Collectively, these results indicate that overexploitation of land resources had large and prolonged effects on soil salinization, which is a lesson to be learned for integrated land management in similar ecotones in arid zones
