福建省蒲田荔城区季节性蔬菜地综合环境质量评价

借助野外调查采样分析和GIS技术进行福建省荔城区季节性蔬菜地综合环境质量评价。研究结果表明荔城区季节性蔬菜地综合环境质量以清洁和尚清洁为主,占季节性蔬菜地总面积的82.23%,表明全区季节性蔬菜地综合环境质量较高,但全区轻、中、重度污染的季节性蔬菜地也占有相当比例,合计面积占季节性蔬菜地总面积的17.77%;平原区拱辰和黄石镇的季节性蔬菜地污染程度相对较为严重;综合环境质量处于清洁水平的季节性蔬菜地土壤亚类主要有盐渍水稻土、渗育水稻土、潴育水稻土和红壤性土,合计占全区清洁水平季节性蔬菜地总面积的94.70%。在综合环境质量评价的基础上,提出了荔城区蔬菜地合理利用对策。

Evaluation of Multiple Environmental Quality of Seasonal Vegetable Field in Licheng County

Based on the technologies of field investigation, soil sampling, analysis and GIS, the multiple environmental qualities of seasonal vegetable fields in Licheng county, Fujian province were evaluated. The results showed that the areas of unpolluted seasonal vegetable fields were 82.23% of the total seasonal vegetable fields in Licheng, which indicated that the multiple environmental qualities of the seasonal vegetable fields in Licheng were much higher, but those lightly for medially and seriously polluted were 17.77% of the total. The contaminating degrees of seasonal vegetable fields in Gongcheng and Huangshi town were much serious. The soil subtypes of the unpolluted seasonal vegetable fields were saline paddy soil, percogenic paddy soil, periodical waterlogged paddy soil and red soil, the total areas of which were 94.70% of the total unpolluted seasonal vegetable fields in Licheng.
