内蒙古浑善达克沙地南缘景观变化机理研究

探究景观变化的机理,可为景观的可持续发展及调整人类活动的强度和方式提供立论依据.通过对1995年和2000年两期Landsat 7 ETM 影像的对比,结合研究区及其附近的水文、气象台站监测资料以及研究区统计年鉴的资料,以GIS为基本的技术平台,分析了研究区的两个时段的景观状态,得出景观变化在研究区内的区域差异.同时,分析了自然地理结构、自然地理过程、人类活动及气候等在研究区内的区域差异.在遥感影像变化和变化因子典型相关分析的基础上,得出景观变化的内因为景观结构与自然地理过程,人类活动只是景观变化的诱发因子,它通过干扰自然地理过程来诱发景观的变化.

A study on mechanism of landscape changes on the southern edge of Inner Mongolia

Studying on mechanism of landscape changes can supply the reference for utilizing the landscape properly for us to adjust the behavior and intensity of the human activities.According to the ETM+ images of the Landsat 7 between 1995 and 2000,with the data from the hydrology and meteorology monitoring station nearby the studying region,and the statistical yearbooks,the status quo of the two phases was analyzed in this paper by GIS.It can conclude the difference of landscape changes in region and analyze the difference of the natural structure and the natural process and human activities and climate.Based on changes of TM images and analysis of classical factos,the conclusions were drawn as followed:the interior causes of the landscape changes are landscape structure and the natural process,the human disturbs the natural process and then place a premium on the landscape change.
