基于3S技术的采煤沉陷区土地利用变化分析——以淮北闸河矿区为例

以淮北闸河矿区为例,以煤炭资源开发引起的土地资源与环境的演变为研究对象,采用3S技术获取该区主要土地利用类型信息,建立土地利用变化转移矩阵,并对该区的土地利用变化及驱动力因素进行初步分析。研究表明,因矿区内煤炭开采和经济的持续发展,使得矿区土地遭受不同程度的毁损。通过采取合理的城乡规划和土地环境整治工程,矿区的土地仍然得到高效利用。

Land use changes of mining subsidence area based on 3S technology-taking Zhahe Mining Area in Huaibei as the case

With the development and utilization of coal resources ,tremendous changes of the land resource and environment in mining areas have taken place .Huaibei Zhahe mining area is taken as a case in this paper .And the evolution of land resources and environment of coal resources development is taken as the research object ,using the 3S technology to obtain information of the main land use types ,in order to set up transfer matrix of the land use change .This paper makes preliminary analysis on land use change and driving factors of the region .Research show s that ,due to the continuous development of coal mining and economy within the mining area has caused the mining area land damaged .By adopting reasonable urban and rural planning and environmental renovation project ,the land of mining area still can get efficient use because the change trend is mainly affected by the economic development ,population increase and improvement on the quality and level of urbanization .
