摘要
为了揭示地下采煤扰动影响区地表演变特征,选择太原西山矿区杜儿坪煤矿的南三盘区为研究区,以采煤前后5期遥感影像为数据源,以ERDAS、Arc GIS为数据处理平台,采用最小距离分类法进行研究区土地利用信息提取与演变分析。结果显示:1976-2015年期间,林地、草地是研究区的主要土地利用类型,其中,草地呈逐年减少的趋势,所占比例由56.01%减少至6.66%。而灌木林地所占比例则由0%增至40.85%。建筑用地、裸地、道路、园地、耕地等地类所占比例均较少,但所占比例呈现出逐年增长的趋势,是土地利用类型多元化转变的体现。结果表明:研究区内土地利用类型转移过程和方向与煤炭开采扰动及区域发展过程相吻合,通过时序土地利用图揭示地下采煤扰动影响区地表时空演变特征方法可行,数据可靠。
In order to find out the characteristics of surface evolution affected by underground coal mining disturbance, the Nansanpan area of Duerping Coal Mine in Taiyuan Xishan mining area was selected as the research area, the remote sensing images of 5 periods before and after coal mining were taken as data sources, and ERDAS and Arc GIS were used as data processing platforms. Minimum distance classification method was used to extract and analyze the land utilization information in the study area. The results showed that from 1976 to 2015, woodland and grassland were the main land types changing in the study area, grassland showed a decreasing trend year by year, accounting for 6.66% from 56.01%. The proportion of shrub land increased from 0% to 40.85%. The proportion of land for construction, bare land, roads, gardens, cultivated land and other land types was relatively small, but the proportion showed a trend of increasing year by year, which was the embodiment of the diversification of land utilization types. The results indicated that the transfer process and direction of land utilization types in the study area were consistent with the disturbance of coal mining and the regional development process. The temporal-spatial evolution characteristics of the surface in the disturbed area of underground coal mining were revealed through the time-series land utilization map,and the method was feasible and the data was reliable.
