Abstract

[目的]探究采煤塌陷裂隙(塌陷发生2a之后)对坡面土壤水分和植被影响的过程与特征,为采煤
塌陷区域植被恢复与生态环境重建提供理论支持。[方法]通过对神府矿区采煤塌陷产生的裂隙两侧的土
壤容重,土壤水分以及植被状况进行调查分析开展研究。[结果](1)采煤塌陷裂隙的出现会导致周边土
壤松动,致使土壤容重降低。(2)在裂隙走向与坡向呈直角或接近直角的情况下,裂隙的出现阻隔了正常
的坡面径流,裂隙下方由于接受径流变少而导致水分状况变差,裂隙对于坡面土壤水分的影响大约在裂隙
下方3m的范围内;在裂隙两壁处,由于裂隙而出现新的表土面,该处的蒸发效应强烈,裂隙坡面的土壤含
水量低于无裂隙坡面(3)裂隙坡面植被的地上生物量较无裂隙坡面低,且越远离裂隙,地上生物量恢复程
度越高。[结论]在不考虑其他因素的影响下,裂隙的出现会使裂隙处以及下部坡面水分状况变差,进而会
对植被生长产生抑制作用。

[Objective]The effects of mining-induced collapse fracture occurrence(two years after collapse)on
slope vegetation characteristics were demonstrated to provide theoretical support for revegetation and improvement
of ecological environment in the coal mining subsidence area.[Methods]Soil bulk density,soil
moisture and vegetation on two sides of collapse fractures in the Shenfu coal mining area were investigated
and analyzed.[Results](1)The collapse fracture occurrence made surrounding soil loose and thus resulted
to the decrease of soil bulk density nearby.(2)In the case of fracture striking at right angle or close right angle
to slope aspect,the fractures affected soil moisture about 3mslope downward,as the water status in the
slope downward part of the fracture became worse due to the intercepting effect of runoff.In the walls of the
fracture,soil water content on fracture slope was lower than that the one on slope without fracture as a result
of strong evaporation.(3)The aboveground biomass of the vegetation on the fractured slope lower than the
one on non-fracture slope.The farther from the fracture,the higher of aboveground biomass revived.[Conclusion]If no other factors exist,the fracture occurrence can worsen soil moisture condition within it;
and in the downward part,it can further inhibite the growth of vegetation.
