摘　　要：西北地区土地质量地球化学调查实施近20年以来,在解决基础地质问题、耕地保护与质量提升、促进特色农业发展、辅助自然资源管理、地方病防控等方面取得系列成果。笔者在全面分析西北地区1∶25万土地质量地球化学调查数据及典型区研究工作的基础上,重点从土壤元素地球化学参数特征、土壤质量状况、土壤生态问题、特色土地资源状况、土壤碳研究、富Se土壤研究和典型成果应用等7个方面进行系统总结。面临新时代地质事业转型升级,提出了未来西北地区土地质量地球化学调查支撑服务生态文明建设和自然资源管理的工作方向,以及加强基础研究的着力点。In the nearly two decades since the geochemical survey of land quality was launched in Northwest China,a series of achievements have been made in solving basic geological problem,cultivated land protection and quality improvement,promoting the development of characteristic agriculture,assisting natural resource management,and controlling endemic diseases.Based on the comprehensive analysis of the 1∶250000 scale geochemical survey of land quality data and the research of key areas in Northwest China,we summarized the progresses and main achievements in seven aspects,such as characteristics of soil geochemistry parameters,soil quality,soil ecological risk,characteristic land resources,soil carbon,study in selenium-enriched soil,and cases on the application of the results.In the face of the transformation and upgrading of geological undertakings in the new era,we put forward the working direction of geochemical survey of land quality in northwest China to support the construction of ecological civilization and the management of natural resources,as well as the focus of the basic research.
