摘要
利用1996年和2001年土地利用现状图,在GIS支持下对晋江市土地利用动态变化进行分析,并在统计软件DPS中对晋江市占的耕地、建设用地及其社会驱动因子进行灰色关联分析;结果表明,研究时段内土地利用变化幅度大,耕地、林地和未利用地净减,而水域、建设用地和园地净增,土地利用变化的社会驱动力依次为经济类因子、人口类因子及技术类因子,政策的干预作用也不容忽视。
Based on GIS, the spatial progress of the land use in Jinjiang City from 1996 to 2001 is revealed; according to the grey correlation theory, the social driving forces of land use and change are analysed with the help of the counting software DPS. The result shows: since 1996, the range of the land use change is very large; in detail, cultivated land, forest land and un-used land reduce greatly, but water body, build-up land and orchard have a net increase. As far as the regional difference are concerned, the regional difference of un-used land and orchard change is obvious,while that of cultivated land, build-up land and forest land is slight. Further more, the result tell us that the economic factor is the dominate one leading to the change. Then the population factor follows,and the end is the technological factor. Of course, the intervention function of the policy factor can`t be ignored.
