借助GIS技术和动态聚类模型进行区域耕地质量的分级评价 ,结果表明闽侯县耕地资源总体质量较差 ,以中低产耕地为主 ,占耕地总面积的 68 10 % ,耕地主要限制型为砂、粘、冷和瘦限制 ,分别占耕地总面积的 2 5 0 4%、12 5 8%、12 17%和 15 2 7%。通过中低产田改良 ,全县耕地的增产潜力巨大。在区域耕地质量评价的基础上 ,探讨了闽侯县耕地合理利用的对策。
With the help of GIS technology and dynamic clustering model, the grading evaluation of arable land quality in the region showed that the overall quality of cultivated land resources in Minhou County was poor, with medium and low yielding arable land accounting for 68.10% of the total cultivated land area and the main limiting type of arable land being sand , Sticky, cold and lean, accounting for 250.4%, 125.8%, 12.17% and 15.27% of the total arable land, respectively. Through the improvement of middle and low yield farmland, the yield potential of arable land in this county is huge. Based on the evaluation of the quality of cultivated land in the region, the countermeasures for the rational utilization of cultivated land in Minhou County were discussed.
