摘　　要：富硒土壤是发展富硒产业的天然载体和宝贵资源。如何根据地区特点,建立具有针对性的耕地质量评价体系,是客观衡量耕地质量的必然要求。同时耕地利用分区研究可以为地方科学、合理利用耕地资源和发展特色农业提供依据。文章以1∶25万多目标区域地球化学调查成果为基础,利用多因素综合评判法对福建省三元区耕地质量状况进行评价,并结合三元区耕地土壤硒元素含量、土壤环境质量及自然保护区和水源保护区等因素,进行耕地利用分区研究。研究结果表明:三元区耕地质量总体良好,土壤磷和钾元素含量是制约该区耕地质量的主要因素。将土壤硒元素作为富硒区耕地质量评价的考量因子之一,客观反映了富硒区耕地质量状况。同时通过利用分区研究,划分出富硒产业发展区、基础农业保护区、土壤环境治理区和生态环境管护区等四种类型区,文章根据不同类型区特点,对耕地提出了不同的利用方向和建设措施。Selenium-rich soil is a natural carrier and valuable resources for the development of Se industry. How to establish an objective cultivated land quality evaluation system according to the regional characteristics is the necessary requirement of the objective evaluation of cultivated land quality. At the same time, cultivated land use zoning research can provide the basis for the local to utilize cultivated land resources and develop characteristic agriculture scientifically and rationally.Based on 1：250000 multi-objective regional geochemical survey results, this article using multi factor comprehensive evaluation method to evaluate cultivated land quality condition of Sanyuan district Fujian Province, and combining soil selenium content of cultivated soil, soil environment quality and nature reserve and water conservation and other factors to research the cultivated land use zoning. Research shows that： overall cultivated land quality of Sanyuan district is good, soil phosphorus and potassium content is the main factor affecting the quality of cultivated land.Through the zoning research, this article divide the cultivated land in the region into four types： Se industrial development zone, basic agricultural protection, soil environmental management areas and ecological environment management and protection area. Depending on characteristics of different types, this article put forward different utilization direction and construction measures of cultivated land.
