城市近郊蔬菜基地环境质量分析与评价

Monitoring and Assessment of Environmental Quality of Vegetable Base in the Suburb

对城市近郊某蔬菜基地的土壤、农用水、大气环境质量进行了监测,用单因子污染指数和综合污染指数进行评价,结果表明,土壤、农用水和大气综合污染指数分别为0.20,0.076和0.58,该蔬菜基地土壤、农用水和大气环境质量达1级标准,属清洁,环境质量状况良好,适合发展无公害蔬菜生产.但该近郊蔬菜基地大气环境质量较土壤和农用水的环境质量差,这与当地的煤矿工业生产有关,因此该城市近郊蔬菜基地的大气环境质量值得关注和改善.

The soil, water and air of vegetable base in the nearby suburb of the city had been investigated and evaluated by single or comprehensive pollution index in this paper. The results showed that the comprehensive pollution index of the soil, water and air was 0.020,0.076 and 0.58, respectively. Therefore, it can be concluded that environmental quality of the vegetable base reached Grand 1, and meet the requirement of production of non-polluted food. However, the quality of air was worse than that of soil and water in the vegetable base. This was due to the production of colliery industry. So the air environmental quality of the vegetable base in suburb needs to be carefully considered and improved.
