安太堡露天矿区土地类型变化研究

研究目的:露天矿是一个比较特殊的土地利用研究对象,在矿区土地利用的过程中,矿区的土地生态系统严重受损,为了矿区的生态安全,通过对矿区开采过程中形成的各种土地类型做相关的探讨,以了解矿区土地类型演变的规律。根据土地类型变化规律为矿区土地复垦提供指导性的原则。研究方法:实证分析和文献资料法,同时采用数学计算的方法,计算出土地类型的单一土地利用动态度及土地类型的转移量。研究结果:以山西省平朔安太堡露天矿为例,采用不同的标准划分了不同的土地类型,提出了露天矿不同土地分类标准之间的联系及破坏分类标准下土地类型的动态变化过程,通过土地类型的单一土地利用动态度及转移总量变化矩阵来分析矿区土地类型的数量变化,突出了土地类型之间的时空演变规律并反映了露天矿区土地类型演变迅速、破环剧烈的特点。

Changes of Land Types in the Antaibao Open-cast Area

The objective of this study is to probe the evolution rule of land types in the process of mining for the ecological safety in the mining areas. The paper is changes of the land types were investigated by using the land information technology in the open-cast area to provide directive principles for the land realamation.Methods of real analysis and documentation were employed,in the same time,by using the mathematical method to calculate the dynamic degrees of certain land types and the land type conversion matrix changes.The paper concluded that it was helpful to enhance the efficiency of monitoring the changes of the land types using the modern land information technology,and a lot of factors must be considered in the process of the land reclamation,such as the technology,planning,the foundation and to establish a successive mineral environment.
