野生动物学报, 2017 山东济宁采煤导致地表塌陷积水,形成大面积新生湿地。在由农田转变为新生湿地后,处于不同塌陷时期的新生湿地,生物多样性发生明显变化。本文对山东邹城鲍店煤矿6个不同塌陷时间的采煤塌陷新生湿地和临近区域的非塌陷区(对照区)鸟类种类、数量、多样性进行了调查和比较研究。共记录鸟类105种,隶属15目39科,其中留鸟29种,旅鸟45种,冬候鸟5种,夏候鸟26种。研究区域新生湿地鸟类数量、多样性均显著高于对照区,表明采煤塌陷区新生湿地已经成为鸟类(尤其是湿地鸟类)重要的栖息地。分析结果表明,非塌陷区(以农田为主 ...

Shuitu Baochi Xuebao, 2017 探讨毛乌素沙地采煤塌陷区土壤水分空间分布及变异特征，为矿区生态恢复提供理论依据。通过线性取样方式，采用经典统计与地统计学方法，研究了塌陷区及非塌陷区（对照）沙丘典型位置0—100 cm范围内土壤水分空间分布特征及变异规律。结果表明：非塌陷区（对照）沙丘典型位置纵横向各层次的土壤水分变化，其概率曲线分布均为正态分布，整体符合毛乌素沙地常规沙丘土壤水分时空变化特征，而采煤塌陷2年后，其纵横向各层次土壤水分的变异程度差异较大，土壤水分流失严重，比对照沙丘减小了近10%～30%，标准差变化在0.54～1.05 ...
