浙江省平阳县富硒土地的保护与开发利用

Protection,Development and Utilization of Selenium Rich Land in Pingyang County,Zhejiang Province

富硒土地是指含有丰富天然硒元素,且有害重金属含量小于农用地土壤污染风险筛选值要求的土地。富硒土地是一种稀缺的资源。平阳县土壤硒的地球化学调查和对农产品中硒的协同调查发现,分布于水头、腾蛟一带的土壤硒含量丰富,稻米中硒含量达到富硒标准的比例较高,鉴于这一带土地集中连片程度较高,土壤环境质量较好,具备资源开发利用条件,认为加强对该区的特别保护和资源的开发利用,具有重要的现实意义。

China Geological Survey(CGS)defined the land with rich natural selenium and harmful heavy metal content less than the screening value of soil pollution risk in agricultural land as se-rich land.Selenium-rich land is a scarce resource,through the geochemical survey of pingyang county soil selenium and selenium in agricultural products,the survey found together in head,teng dumpling of soil selenium content is rich,selenium content in rice to achieve a higher standard of selenium-rich agricultural products;in view of the high degree of land concentrated in this area,the soil environmental quality is good,has the resources development and utilization of the premise,It is of great practical significance to strengthen the special protection and the exploitation and utilization of resources in this area.
