| 摘 要： | 以浙江省慈溪市周巷镇蔬菜基地为例,按照国家发布的<土壤环境质量标准>和<农产品安全质量标准无公害蔬菜产地环境要求>评价,在地理信息系统技术支持下,利用加权指数求和法评价模型,在全国蔬菜地分等标准基础上结合周巷镇实际情况对其蔬菜地进行了分等.评价结果表明:本方法优于国家农业行业标准-蔬菜地分等;周巷镇蔬菜基地中属一等地为9 hm2;二等地为50 hm2;三等地为134 hm2;四等地为90 hm2.所以周巷镇可以建立无公害蔬菜基地. |

| Abstract: | In this paper, vegetable lands of Zhouxiang Town at Cixi City in Zhejiang provience was studied as an example in accordance with "Environmental Quality Standard for Soils" and "Safety Qualification for Agricultural Product - Environmental Requirements for Origin of Non-environmental Pollution Vegetable" of China. With the support of GIS, we adopted the index accumulation method and combined its actual instance and assessed the class of the vegetable lands on the basis of the National (Agricultural) Standard-Class in the Vegetable lands. The results show that our method excels the (National) Agricultural Standard - Class in the Vegetable lands. According to our assessment, among the vegetable lands of Zhouxiang, the first class had 9 hm~2. The second class had 50 hm~2. The third class had 134 hm~2. The fourth class had 90 hm~2. Non-pollution vegetable land may be based. |
