Abstract:

Based on collection of scientific publications from the National Field Science Research Station of Farmland Ecosystem in Linze since 2007, the article reviews the research progress in arid land soils and oasis agriculture. There were four main fields, which included soil fertility and agricultural management, soil moisture and nutrient cycling, vegetation-soil interactions, and soil biodiversity and functioning. By synthesizing the research content, all researches were grouped into seven topics: soil ecological processes in sand-fixing vegetation regions, macropore structure and associated hydrological processes, nitrate leaching in farmland and its impact on groundwater, evolution of soil fertility in oasis farmland and carbon-nitrogen sequestration, assessment of carbon storage in desert grasslands of the Hexi Corridor, water productivity in oasis croplands and its regulatory, and soil carbon and nitrogen cycling and influencing mechanisms in mountainous regions. These findings significantly advance the understanding of soil ecological processes and agricultural sustainability in arid regions, providing a scientific basis for regional ecological conservation and agriculture development. Furthermore, future studies should prioritize multidisciplinary approaches and technological integration, with strengthened efforts in long-term ecosystem monitoring, coupled modeling of soil-vegetation-hydrological processes, optimized ecosystem management, and the translational application of scientific findings.

Key words: arid land, oasis agriculture, sandy-fixing vegetation, porosity properties, nitrate leaching, farmland water productivity
