基于RS的平顶山矿区土地利用动态变化研究

Study of Dynamic Change of Land Use in Pingdingshan Mining Area Based on RS

首先阐述了煤炭开采对平顶山矿区生态环境的主要影响,然后利用RS技术定量分析了平顶山矿区1994~2002年土地利用动态变化过程,并求得研究区土地利用变化的转移矩阵,据此分析平顶山矿区1994~2002年间土地利用变化的空间过程。同时运用马尔柯夫模型,对土地利用动态变化及演变趋势预测进行了分析,从而达到全面把握矿区土地变化规律的目的,最后提出了矿区生态可持续发展对策。

At first,the main affection of coal mining to environment was expounded in Pingdingshan mining area,and then,the process of the land use development and the situation of all the categories of the land use transformation in Pingdingshan mining area from 1994 to 2002 are quantitatively analyzed with the technique of RS.It is feasible to calculate the transformation matrix of land use showing spatial pattern of land use distribution in unit of image pixel,which revealed the mining area spatial process from 1994 to 2002.Moreover,the land use development and the variation tendency area were analyzed and predicted by using development degree of the land use and the model of Markov process.At last,the countermeasure of ecology sustainable development is brought forward.
