| 摘 要： | 通过对准噶尔盆地绿洲-沙漠过渡带的植被种群和覆盖度的调查,以及1989年和2000年两期TM影像景观格局的解译,运用时间动态度和Ripley's K函数的方法分析了准噶尔盆地绿洲-沙漠过渡带植被的时空变化特征.结果表明,1989～2000年,研究区内人为垦地幅度较大,农田面积增加,而天然植被区域被垦地利用或破坏,造成植被面积减少,总的覆盖度降低,同时沙化面积加大.

| Abstract: | In this paper spatio-temporal change characteristics of vegetation on oasis-desert ecotone of Junggar basin was analyzed, through the investigation on the vegetation species and vegetation cover degree in oasis-desert ecotone of Junggar basin, the interpretation on the two landscape pattern TM image in 1989 and 2000, and applying the method of time dynamic degree and Ripley's K function. The results showed that from 1989 to 2000, vegetation area was decreasing, cover degree was descending and desertification area was increasing because of increasing of artificial cultivation area and farmland area and deareasing of natural vegetation. |
