| 摘 要： | 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。

| Abstract: | The qualities of regional cultivated land were evaluated and classified by GIS technology and the model of dynamic cluster analysis. The results showed that the overall qualities of the cultivated land were lower in Minhou County. The cultivated land with middle and lower yield was 68.10% of the total. The major limiting factors of the cultivated land were sand, clay, temperature and nutrient,accouting for 25 04%, 12 58%, 12 17% and 15 27% of the total, respectively. The potentialities of increasing production of the cultivated land were huge by improvement of the cultivated land with middle and lower output. The rational use countermeasures of the cultivated land in Minhou County were also discussed based on the results of evaluation. |
