摘 要:指出了宁波市耕地安全的主要问题,并运用人均占有耕地面积、人均耕地后备资源量、耕地补充系数和耕地质量指标等4项指标进行了耕地的安全评价,结果表明:除耕地质量指标大多能达到安全或高度安全状态外,其余指标都处于值得关注状态以下,尤其是受污染比例指标和人均耕地面积指标属于高度危险状态和危险状态。为提高耕地的安全性程度,必须建立地区性的耕地安全体系,实现耕地可持续利用。This paper points out the main problems of the safety degree of cultivated land of Ninbo, and evaluates the safety degree of cultivated land of our city according to the following indexes: the indexes of the area of cultivated land per capita of our city, the indexes of the amount of reserve cultivated land recourse, the supplementary coefficient of cultivated land, the indexes of the quality of cultivated land. The result shows that the indexes of the quality of cultivated land almost show safety and high safety, but other indexes are all worth paying close attention to. Especially, the indexes of the inverse proportion of pollution show high danger and the indexes of the area of cultivated land per capita show danger signal. To improve the safety degree of cultivated land of our city, we must set up the regional system of the safety degree of cultivated land, and try our best to make continuable using of cultivated land come true.
