摘要
依据土地利用变更调查数据,采用土壤调查与3S技术相结合的方法,构建基于补充耕地、质量建设耕地的质量评价体系,测算耕地的质量等别。结果表明:研究区2011—2013年,补充耕地的数量较占用耕地多21.65 hm^2,质量略有提高,较好地落实了耕地占补平衡政策,做到"数质并重"。其中,土地整治、农业结构调整补充的耕地质量等别较高。在质量建设耕地中,中低等别耕地建设后质量提升幅度大于高等别耕地。以耕地质量更新评价结果为基础,结合高标准基本农田建设、土地整治规划等成果,将县域耕地划分为4类保护区,实现了耕地资源的分区保护。
The research, according the land use survey data, combing soil survey and 3S technology method, building the new cultivated land quality evaluation system, measures the quality of the cultivated land. The result shows that the quantity of cultivated land in research area has increased 21.65 hm^2 from 2011 to 2013; the average grade of new increasing cultivated land has slightly higher than the decreasing cultivated land, implementing land policy of dynamic balance. The quality of barren farmland has greater improvement than other cultivated land which has higher grades before construction. The research, based on the evaluation results, reasonable divides the cultivated land into four kinds of different protection and construction types, ensuring the effective protection of cultivated land resources.
