以黄土沟壑区的采煤沉陷区为研究对象,以地面数字高程模型和开采沉陷预计结果为基础数据,基于Arc GIS平台对煤矿开采沉陷区的地形数据进行分析处理,研究开采沉陷前、后地形因子的变化特征,并对不同地形因子之间的相关性进行了分析。研究结果表明:黄土沟壑区地面高程、坡度、坡向、起伏度等各种地形因子均受开采沉陷影响而发生改变,开采沉陷和地形因子之间存在明确的量化关系,而平均高程、起伏度、曲率、沟壑密度等因子与地面坡度之间存在显著的相关性。研究结果有助于揭示煤矿开采沉陷区的地形地貌演变规律,为保护西部矿区的生态环境提供技术支持。
Taking the coal mining subsidence area in the loess gully area as the research object and the terrestrial digital elevation model and the mining subsidence prediction result as the basic data, the topographic data of the mining subsidence area was analyzed and processed based on the Arc GIS platform. Factors of the change characteristics, and the correlation between different topographical factors were analyzed. The results show that all kinds of topographic factors such as ground elevation, slope, aspect and undulation are changed under the influence of mining subsidence. There is a definite quantitative relationship between mining subsidence and topographic factors, while the average elevation, undulation , Curvature, gully density and other factors and the slope of the ground there is a significant correlation between. The results of this study are helpful to reveal the evolution of topography in the subsidence area and provide technical support for the protection of the ecological environment in western mining areas.
