Land exploitation resulting in soil salinization in a desert–oasis ecotone
Understanding the process of agricultural land expansion and its impact on soil properties is crucial for land management and environmental health. A desert–oasis ecotone is typically located between an oasis at the lower reach of inland rivers and neighboring desert in arid regions, and acts as an interactive zone between irrigated farmland and the natural desert ecosystem. The arid region of northwest China has experienced dramatic land exploitation since the 1960s and soil salinization has been a serious environmental problem ever since.
