摘要
在RS和GIS支持下,分别以2001年和2011年的TM遥感数据影像数据研究贵州省紫云县石漠化现状及演变趋势。结果表明:紫云县42.04%的土地发生石漠化,其中轻度、中度、强度石漠化分别占总面积的31.7%、5.38%、4.96%;石漠化的分布与地貌、高程、坡度、植被以及水文气候等因素密切相关;通过RS和GIS技术直观、全面的反应出该地区石漠化的发展趋势,为当地石漠化灾害防治和生态环境保护提供重要决策依据。
In support of RS and GIS,the present situation and evolution trend of rocky desertification are studied by using 2001 and 2011 TM remote sensing image data respectively in Ziyun County,Guizhou Province.The result shows that： Ziyun County,42.04% of the land occurred rocky desertification,mild、moderate、intense rocky respectively of the total area of 31.7%、5.38%、4.96%;Rocky desertification distribution is closely related to factors such as topography,elevation,slope,vegetation and hydrology climate;RS and GIS technology is intuitive,comprehensive response to the rocky desertification trends and provide the important decision-making basis for the prevention of rocky desertification disasters and ecological environmental protection in this region.
