| 摘 要： | 土地沙漠化是影响全球生存环境和可持续发展的重大灾害性问题，本文从景观和景观生态学出发，论述了沙漠化景观稳定性和景观干扰的特征、本质及测度，特别强调了自然因素和人为活动对沙化景观干扰所产生的影响，最后论述了依据地理信息系统和遥感图像建立沙化景观干扰图的框架，为从景观尺度研究沙漠化灾害和防治沙漠化提供参考。

| Abstract: | Land desertification is a significant disastrous problem which produced a great impact on global live supporting environment and sustainable development.This paper discusses the landscapes stability and the characters,essential and measurement of landscape disturbances from landscapes and landscapes ecology,in particular,the influence of natural factors and human activities on landscape disturbance have been stressed.Finally the frame of landscape disturbance mapping is set up based on remote sensing and GIS,which gives a reference to study desertificaton disaster and disaster reduction. |
