摘要
该文通过获取湖北省宜昌市五峰土家族自治县近22年的四期Landsat TM遥感影像,运用ENVI、ARCGIS软件,结合统计年鉴、文献资料,研究了五峰县土地利用变化情况和驱动力因素。结果表明:(1)变化最明显的是建设用地和林地,草地、水域变化不大。1993—2015年,建设用地增加了7 557hm2,林地减少了9 836hm2。(2)1993—2001年,耕地增加46%,林地减少9.88%,未利用地增加了10.23%。(3)2001—2015年,耕地面积减少29%,林地总量增加5.3%,未利用地减少44%。(4)五峰县土地利用变化的社会经济驱动力主要是地区生产总值、农民人均纯收入、全社会固定资产总额、入境旅游人数、财政总收入等因素。
Four different times land use data which were interpreted by remote sensing data in the last 22 years, were analyzed through ENVI and ARCGIS software. Statistical yearbooks were used to analyze Wufeng County land use change characteristics and driving power factors. The study results showed ： （ 1 ） Construction land and woodland had changed a lot. Grassland and waters had little changes. During the period from 1993 to 2015, construction land increased by 7557 hectares, and woodland reduced by 9 836 hectares. （2）During the period from 1993 to 2001, Cultivated land increased by 46%. Woodland declined by 9.88%, Unused land increased by 10.23%. （3）During the period from 2001 to 2015, cultivated land declined by 29%. Woodland increased by 5.3%.
