摘要:

［目的］为实现对石台县土壤天然富硒资源的合理利用，促进石台县经济发展。［方法］文章通过实地调查与资料分析的方法，研究了石台县土壤硒资源空间分布的特点和土壤富硒资源利用途径。［结果］石台县土壤硒均值为0.5556mg/kg，达到富硒水平，石台县富硒地区占全县的28.73%，中硒地区占全县面积的67.62%，富硒地区主要分布在仙寓镇、七都镇、大演乡、丁香镇、仁里镇。石台县土壤硒含量主要与成土母岩、土壤质地、成土过程、土壤有机质和人类活动等影响因素有关。［结论］石台县土壤硒资源利用可以通过发展富硒茶、富硒米、富硒养生旅游、生态富硒高山蔬菜和瓜果、富硒中药材、富硒黑猪肉和富硒牛肉等富硒产业，富硒茶区域应设置在仙寓、七都、大演、矶滩、横渡5个乡镇，富硒米种植区域应设置在台县东部的七都镇和南部的仙寓镇，富硒养生旅游可以设置在横渡镇、仙寓镇、大演乡、丁香镇、小河镇，生态富硒蔬菜和瓜果应集中分布于石台县横渡、仁里、矶滩、七井等地，富硒养殖业可以分布在石台县西部的小河镇。

Abstract:

In order to realize the reasonable utilization of natural selenium-enriched resources and promote the economic development of Shitai county, this paper studied the spatial distribution characteristics of soil selenium resources and the utilization of selenium-enriched resources by field investigation and data analysis. The results showed that the soil selenium content in Shitai county was 0.555 6 mg / kg, the Se-enriched area accounted for 28.73% of the county area, which mainly distributed in Xianyu town, Qidu town, Dayan town, and Renli town. The influencing factors included the parent rock, soil texture, soil forming process, soil organic matter and human activities. Based on the Se-enriched resources in Shitai County, it should develop Se-enriched tea in Xianyu town, Qidu town, Dayan town, Jitan, and Hengdu town, Se-enriched rice in Qidu town and Xianyu town, Se-enriched health tourism in Hengdu, Xianyu, Dayan village, Xiaohe town. Se-enriched vegetables and fruits should concentrated in Shitai county, Hengdu town, Renli town, Jitan town, Qijing town, and aquaculture can distributed in the river west of the town of Shitai county. It can realize the reasonable utilization of natural resources of selenium rich soil in Shitai county, and promote the economic development of Shitai county.
