【摘要】：随着我国矿产资源的大力开发,许多矿区发生了严重的地质灾害与环境污染,给城市经济的健康发展与人民群众的生命财产带来了威胁。研究以唐山矿为例,根据研究区的的具体情况,以多源数据为基础,采用“3S”技术手段,实现对矿区空间变化立体层面上的监测与分析。矿区空间变化包括地表地物变化与地表地貌变化。因此,针对研究区具体情况,研究选取了TM影像、ALOS影像、Geoeye影像作为多尺度遥感数据源,DEM数据作为主要高程数据源,结合相关地形图,文字统计资料作为多源数据。通过多种技术手段实现矿区空间变化监测与分析。首先,通过指数法,阈值法,决策树分类等数据处理方法,实现对矿区积水、植被、固体废弃物等监测对象信息的提取,对提取结果进行了定性与定量分析,并对不同尺度的遥感数据处理结果进行对比,实现宏观、局部、细节层面上的空间变化监测与分析,得到矿区地表地物的变化规律。之后,选取重点监测区域的DEM数据,结合地表地物变化信息以及相关地形图,通过同一区域的不同时段数据对比分析,得到研究区域地表地貌的变化规律。最终,通过地表地物变化规律和地表地貌变化规律的结合,实现对矿区空间变化的分析。通过对多源数据的处理,实现了对矿区空间变化的监测与量化分析,可在特定范围内比较直观、精确地确定矿区的动态变化,为沉陷区的综合治理提供科学依据。
[Abstract]:With the development of mineral resources in China, serious geological disasters and environmental pollution have occurred in many mining areas, which threaten the healthy development of urban economy and the life and property of the people. Taking Tangshan Mine as an example, according to the concrete situation of the study area, based on the multi-source data and using "3s" technique, the paper realizes the monitoring and analysis of the spatial change in the mining area on the stereoscopic level. The spatial change of mining area includes the change of surface and geomorphology. Therefore, according to the specific situation of the study area, the study selects the TM image ALOS image Geoeye image as the multi-scale remote sensing data source Dem data as the main elevation data source, combines the correlation topographic map, the text statistics data as the multi-source data. The spatial change monitoring and analysis of mining area is realized by various technical means. First of all, through the index method, threshold method, decision tree classification and other data processing methods, to achieve the mining area water, vegetation, solid waste and other monitoring object information extraction, qualitative and quantitative analysis of the results, The results of remote sensing data processing at different scales are compared to realize the monitoring and analysis of spatial changes in macroscopic, local and detailed levels, and the law of change of surface and ground objects in mining area is obtained. After selecting the DEM data of the key monitoring area, combining with the change information of the surface features and the related topographic map, through comparing and analyzing the data of the same area in different periods, the change law of the surface geomorphology in the study area is obtained. Finally, the spatial change of mining area is analyzed through the combination of the law of change of surface features and the law of surface geomorphology change. Through the processing of multi-source data, the spatial change of mining area can be monitored and analyzed quantitatively. The dynamic change of mining area can be determined intuitively and accurately in a specific range, which provides a scientific basis for the comprehensive management of subsidence area.
