基于多时相遥感的煤矿区LUCC信息图谱

在地学信息图谱理论和GIS的支持下,以多时相遥感为LUCC数据源,针对煤矿区的特点,提出了建立四种LUCC信息图谱的方法。选择唐山市古冶区为研究对象,以3个时相(1987年、1992年和2001年)遥感图像为数据源,利用ENVI4.0对图像进行预处理和人机交互解译,通过ArcView3.2进行空间分析,生成了四种类型的LUCC信息图谱,计算了LUCC转移矩阵和概率转移矩阵。以1987-2001年时段为例,对空间格局和演变过程的信息图谱进行了详细分析。研究表明:基于多时相遥感数据,利用地学信息图谱研究煤矿区LUCC是一种先进可行的技术途径。

Research on LUCC information atlas based on multi-temporal remote sensing in coal mining area

In support of geo-information atlas theory and GIS,taking multi-temporal remote sensing as data source of LUCC,and method of establishing four species of LUCC information atlas are presented aiming at characteristics of coal mining area.Guye district in Tangshang city is the study object,taking three temporal(1987,1992 and 2001) remotely sensed imageries as data resource and imageries were pretreated by ENVI4.0 and interpreted by human-computer interaction,and spatial analysis was finished by ArcView3.2,and four kinds of LUCC information atlas were created,and transfer matrix and probability transfer matrix of LUCC were calculated.The information atlas of space pattern and evolutionary process were analyzed in detail taking time interval from 1987 to2001 as an example.The case study indicates that using geo-information atlas to study LUCC of coal mining area could be a advanced and feasible technique approach.
