Abstract

Soil, atmosphere, water and quality of agricultural product constitute the content of land ecological quality. Cixi City, through survey pilot project of basic farmland quality, carried out high precision soil geochemical survey and survey of agricultural products, irrigation water and air quality, and established ecological quality evaluation model of land. Based on the evaluation of soil geochemical quality, we conducted comprehensive quality assessment of atmosphere, water, agricultural products, and assessed the ecological quality of agricultural land in Cixi City. The evaluation results show that the ecological quality of most agricultural land in Cixi City is good, and there is ecological risk only in some local areas such as urban periphery. The experimental results provide demonstration and basis for the fine management of basic farmland and ecological protection.
