摘要：通过研究采煤塌陷裂缝对坡面土壤水分分布的影响,以及不同坡向上的裂缝周边土壤水分状况,以期找出坡面及不同坡向上的裂缝对土壤水分的影响机制。结果表明:不同坡向上的土壤水分状况阴坡>坡底平地>坡顶>阳坡;坡面下部水分状况比上部好,坡面上的采煤塌陷裂缝对裂缝上坡位土壤水分的影响大于下坡位;裂缝对裂缝处土壤水分影响最大,在不同土壤层次上土壤水分含量均是20—40 cm>10—20 cm>0—10 cm。
The paper found out the effect mechanism of cracks of slope surface and different slope directions to the soil moisture through studying on the influence of collapse and cracks because of mining to the distribution of soil moisture of slope surface and soil moisture condition of the surrounding soil of cracks in the different slope directions.The outcomes show that a) the conditions of soil moisture of slopes with different directions are shady slope>the bottom of the slope>top of slope>sunny slope;b) the condition of soil moisture of the lower part of slope surface is better than that of the upper part and the influence of mining collapse and cracks at the upper part is greater than that of the lower part;c) the influence of cracks is the maximum to the soil moisture near the crack of soil.The soil moisture of different layers is 20-40 cm >10-20cm>0-10 cm.
