闽侯县耕地土壤环境质量评价

Soil Environmental Quality Assessment of Cultivated Land in Minhou County

在实地调查和分析测试的基础上,借助GIS技术,进行闽侯县耕地土壤环境质量评价,结果表明,全县耕地土壤环境质量总体较高,清洁和尚清洁的耕地占全县保护区耕地总面积的98.98%,处于轻度污染水平的仅占1.02%。环境质量处于清洁水平的土壤类型主要有黄泥田、灰泥田、青泥田、黄泥砂田和红泥土等土属,处于轻度污染水平的土壤类型主要有黄泥田等土属。在环境质量评价的基础上,提出了闽侯县耕地土壤合理利用的对策。

Through field survey and soil samples analysis, the soil environmental quality of the cultivated land in Minhou county, Fujian province was assessed by using GIS technique. The results showed that the soil environmental quality of the cultivated land was rather high as a whole, about 98.98% of the cultivated land in protective area was dean or still clean, and only 1.02% of the cultivated land was mildly polluted. The soil types whose environmental quality was high mainly included yellow mud field, gray mud field, blue mud field, yellow mud sandy field, red mud soil; the soil genus which was mildly polluted included yellow mud field. Based on the assessment results of soil environmental quality, the paper put forward the countermeasures for the rational utilization of the cultivated land in Minhou county.
