摘要：

收集了甘肃临泽农田生态系统国家野外科学观测研究站（简称临泽站）自2007年以来在干旱区土壤与绿洲农业研究方向发表的科研论文，系统综述了临泽站在土壤肥力与农业管理、土壤水分与养分循环、植被与土壤互作关系和土壤生物多样性与功能等领域开展的研究工作，并通过归纳汇总，从固沙植被区土壤生态过程、土壤大孔隙特征与水文过程、绿洲农田硝态氮淋溶及地下水环境影响、绿洲农田土壤肥力演变与碳氮效应、河西走廊荒漠草地碳储量评估、绿洲农田水生产力调控和山区土壤碳氮循环及影响机制等7个研究主题对相关的研究成果进行了详细论述。指出，临泽站以往研究成果深化了对干旱区土壤生态过程与农业可持续性的理解，为区域生态保护与农业发展提供了重要科学依据；在未来研究中还需强调多学科交叉与技术融合，在生态系统长期观测、土壤-植被-水文过程耦合模拟、生态系统优化管理以及科研成果的转化应用等方面进一步加强。

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
