| 摘 要： | 利用浙江省富阳市1984年和1999年2期TM影像数据,结合土地利用动态变化研究方法,对富阳市竹子资源和其它主要土地利用类型的动态变化进行了研究分析.结果表明:1984-1999年期间,富阳市土地利用变化较快,在单一类型中,园地的变化速度最快,耕地的变化速度最慢;竹子资源数量下降,年平均下降2.47%,主要转移对象是其它林地;竹子的动态变化在富阳市25个乡镇中存在着区域差异;在变化期间,其它林地的稳定性最高,同时也是转入量最高的一种类型,数量大幅增加.

| Abstract: | Landsat TM images of 1984 and 1999 that cover the whole Fuyang Citywere used to analyze the dynamicchange p rocess of bamboo and other land-use types. The results of analyze indicated: that from 1984 to 1999, therate of land-use change was rap id. For the rate of change of each land-use type, garden p lot was the most rap idone, and farmland was the slowest one. The area of bamboo forest decreased. The annual average rate of decreasingof was 2. 47%. Most of decreased bamboo forest was transferred to other forest. There was regional diversity ofbamboo forest change in the 25 towns of Fuyang. From 1984 to 1999, the stability of other forest was the highest,and it is the type that got the most transference from other land-use type. So the area of other forest increased largelyin the changed period. |
