- 摘要:
- 绿洲-荒漠生态脆弱带（ECOTONE）介于绿洲和荒漠之间，对绿洲起着屏障作用，它在维护干旱区生态系统的平衡方面起着重要作用，深入研究这一特殊地带的环境演变过程、特征及形成机制对于揭示其生态学实质、维护和发展绿洲具有重要的实践意义。选择于田绿洲为研究区，以遥感技术为依托，对2个时相的陆地卫星数据及相关统计资料进行了处理，利用得到的土地覆盖差值图像，定量分析评价了该地区生态脆弱带1989-2003年间的变化趋势，在此基础上，根据该地区生态环境特点提出了若干有效生态保护及复原措施。为西部干旱地区合理开发绿洲、可持续发展绿洲资源及改善绿洲生态环境等提供新的研究方法和科学依据。
- Abstract:
- Ecotone is located between oasis and desert which plays the important role of protecting oasis and maintaining eco-system balance in arid region. There has practical significance for discovering its ecological nature, maintaining and developing oasis to study the process of environmental transformation profoundly, characteristics and forming mechanism. This paper selects Yutian Oasis as research area. Two temporal satellite data and related information based on RS technology are handled and the changing trend from 1989 to 2003 in the ecotone is quantificationally evaluated using land-cover dynamic change figure. On this basis, several useful measures to conserve and restore ecological environment are put forward according to characteristics of the area’s ecological environment. In this way, new research method and scientific foundation are provided for exploring oasis reasonably, utilizing sustainable resources and improving oasis’s ecological environment in western arid region.
