摘要

根据山西省阳泉市煤业集团三矿280自燃煤矸石山坡面的观测资料

对采用不同坡面覆盖方式的样地的水土保持效益和植被生长情况进行了分析研究。结果表明

采用煤矸石和黄土混合覆盖的煤矸石山坡面蓄水保土效果显著

植被恢复状况良好。在同一时期内

随着矸石覆盖率的增加

煤矸石样地的土壤含水量也随之增加。在煤矸石和黄土混合覆盖的样地中

矸石覆盖间隔0.15～0.25m

覆盖率35%～45%的样地

保土效益最好

植被恢复最佳。

Abstract

Soil and water conservation benefits and vegetation growth in selected plots with different coverswere analyzed based on the observed data on the No 280spontaneous combustion gangue slope in the CoalMine III

Yangquan Coal Industry Group

Shanxi Province.Results indicate that the plots covered by mixedmaterial of gangue with loess have significant soil and water conservation benefits

accompanying favorablevegetation recovery.Meanwhile

soil moisture content in the coal gangue plots is accumulated with the increased gangue cover.Among the selected plots covered by the mixed gangue with loess

the one with thegangue cover intervals of 0.15～0.25mand gangue cover degrees of 35%～45%is the optimal cover measurefor soil and water conservation and vegetation restoration.
