| 摘 要： | 在栅格空间主要农作物生产潜力和用地适宜性评价基础上,采用地理信息系统与数学模型集成技术,研究探讨区域耕地价值及其空间分异规律.结果表明:(1)福建省耕地单位面积价值变化于84.09-750.53万元.hm-2,总价值为5.92万亿元;(2)福州市耕地总价值(7053.93亿元)>泉州(6774.95亿元)>漳州(6639.12亿元)>南平(4570.49亿元)>龙岩(4478.87亿元)>宁德(4254.15亿元)>三明(3916.01亿元)>莆田(2909.00亿元)>厦门(1234.06亿元);(3)耕地单位面积价值量总体上呈现由闽东南、闽南沿海地区向闽东、闽西和闽北丘陵山地区递减的趋势.

| Abstract: | The values of regional cropland resource and their spatial variation were evaluated and discussed by geographic information system(GIS) integrated with mathematical models on the basis of evaluation of the potential productivity and land use suitability of main crop in grid dimension.The conclusions showed as follows:(1) The value per unit area of cropland resource in Fujian ranged from 84.09×104 to 750.53×104 yuan·hm-2 and the total values were 5.92×1013 yuan.(2) The total values of cropland in prefecture showed following tendency: Fuzhou(7053.93×109 yuan)>Quanzhou(6774.95×109 yuan)>Zhangzhou(6639.12×109 yuan)>Nanping(4570.49×109 yuan)>Longyan(4478.87×109 yuan)>Ningde(4254.15×109 yuan)>Sanming(3916.01×109 yuan)>Putian(2909.00×109 yuan)>Xiamen(1234.06×109 yuan).(3) The value per unit area of cropland resource in Fujian decreased from the coastal areas in Southeast and South Fujian to the mountain and hill areas in East,West and North Fujian. |
