摘　　要：天然富硒土地资源高效开发利用在支撑服务脱贫攻坚与乡村振兴、健康中国等国家战略方面具有重要意义。土地质量地球化学调查二十年来,利用调查数据研制了《天然富硒土地划定与标识(DZ/T 0380-2021)》行业标准。调查发现了53.9 km^(2)富硒土地资源,基本查明了全国主要农耕区富硒土地资源空间分布特征及富硒土壤成因。通过建立富硒地块信息档案、提出产业布局建议、助推示范基地建设等方式积极推进成果转化应用,形成了以“江西赣州”、“湖南新田”和“青海平安”为典范的“地质+特色农业”的富硒土地高效利用开发模式,取得了显著的经济成效。同时阐述了天然富硒土地资源高效开发利用面临的主要问题和制约因素,并提出建议和对策。The efficient development and utilization of natural selenium-rich land resources is of great significance in supporting national strategies such as poverty alleviation,rural revitalization and healthy China.Over the past twenty years,the land quality geochemical survey of the industry standard"Delimitation and standardized logo for natural selenium-enriched of land(DZ/T 0380-2021)"has been carried out.The survey found 53.9 km2 of selenium-enriched land resources,and identified the spatial distribution characteristics and causes of selenium-enriched land resources in major farming area.Through establishing information files of selenium-enriched plots,proposing industrial layout suggestions and boosting the construction of demonstration bases,the application of achievements has been promoted actively.Based on the development mode of efficient utilization of selenium-enriched land"geology+characteristic agriculture",Ganzhou in Jiangxi,Xintian in Hunan and Pinan in Qinghai has achieved remarkable economic results.The main problems and restrictive factors affected the efficient development and utilization of natural selenium-enriched land resources are expounded,and suggestions and countermeasures are put forward.
