以神府-东胜煤田补连塔矿风沙区为例,通过野外调查和观测,系统分析了塌陷1 a/T2005年、塌陷2 a/T2004年和非塌陷区植被群落变化特征、塌陷强度(地表破损率)对植被群落变化的影响以及植被群落变化对风蚀的响应.结果表明:补连塔风沙区植被的丰富度排序为:草本＞灌木＞乔木,群落的总丰富度受草本丰富度的影响,群落结构总体不稳定;塌陷区植物群落的变化是该矿风沙区地表塌陷后加快风蚀进程的重要指征,地表破损率与植被生长状况呈负相关关系;采煤塌陷直接导致植被的死亡率增大,降低了塌陷区植被防风固沙的作用,从而使塌陷区发生严重风蚀.

Taking Bulianta coal mine in Shenfu-Dongsheng coal field as study object, effects of coal mining subsidence on the changes of vegetation community in one year(T2005) and two-year(T2004) subsided areas and non-subsidence areas were investigated. The results showed that (1) the order of vegetation richness was herbal>shrubs>arbor, the richness of general vegetation was greatly effected by the richness of herbaceous species, resulted in an unstable vegetation community, (2) the most important indicator of the accelerated wind erosion was the change of vegetation community, the rate of destruction in the land surface was negatively correlated to the growth of vegetations; and (3) the subsidence in the coal mining area directly resulted in the increase of the rate of mortality and the decrease of the sand-fixation function of the plants, and make serious wind erosion in the subsided area.
