基于空间统计学的矿山开发状况变化信息定量分析研究——以福建省宁德市为例

Quantitative analysis and research of the change information of mine development based on spatial statistics:—a case study of Ningde City

矿产资源开发状况变化信息的提取是有效整顿和监管矿产资源开发秩序的重要环节,文中以福建省宁德市为研究区,通过遥感影像监测矿产资源开发状况变化信息:范围变化、纹理变化,引用空间统计学半变异函数思想,构建能够反映矿产资源开发状况变化信息的数学模型,结合半变异函数值总结矿产资源开发状况变化程度的定量评价方法,实现对矿产资源开发状况变化信息中伪变化、深挖等现象的定量分析,从而降低遥感影像伪变化、解译人员工作经验等客观因素对矿产资源开发状况变化信息提取产生的影响。

The extraction of information on mineral resources development is an important link to achieve effective rectification and supervision of mineral resources development order.This paper takes Ningde City,Fujian Province as the research area,and extracts information on the development of mineral resources by analyzing of remote sensing:the scope changes and texture changes,Combining the idea of semi-variogram in spatial statistics,constructing a mathematical model suitable for the extraction of information on mineral resources development,establishing a quantitative evaluation standard for judging the degree of change of mineral resources development by semi-variogram values,and realizing the quantitative analysis and evaluation of the phenomenon of pseudo-change and deep digging,this paper can reduce the impact of objective factors such as the quality of remote sensing images and the working experience of interpreters in the process of extracting information of mineral resources development.
