The experimental results suggested that there were some rules during the fermentation as follows: pit temperature increased rapidly and then dropped at the beginning of the fermentation and kept stable eventually at 20～22 ℃; there was slight change in yellow water pH value at first and then pH value decreased gradually in middle fermentation stage and finally kept stable; the change rules of total acids of yellow water were opposite to pH change rules; the reducing sugar of yellow water increased at first and then dropped and kept stable eventually; there was almost no change in alcohol content of yellow water in prior fermentation period, and then it increased rapidly and dropped slowly and finally kept stable; gas production rate was as high as 550 L/d within the first week in fermentation and then dropped undulatingly and changed to zero or even negative gas production rate.

窖池温度在发酵前几天迅速升高，然后下降，最后趋于稳定，保持在20～22 ℃；黄水pH开始变化不大，中间逐渐下降，最后趋于稳定；黄水的总酸变化与pH相反；黄水中还原糖先升高后下降，最后基本保持稳定；黄水中酒精含量在发酵前期变化不大，后期先是迅速升高，然后缓慢下降，最后趋于稳定；在发酵前期一周内，产气量很大，最高达550 L/d；之后产气量呈波动式下降并逐渐平稳，最后趋于零甚至负产气量。

Over a 20-year period there was no increase in soil water content in the grazed grassland at depths of 2～9.9 m. There was a small increase(0.5～3.7 mm/a) in soil water content in the protected grassland, however the slow rate of increase suggests that at least 150 years would be needed for ungrazed grassland soils to regain water content similar to that present prior to planting trees. Recharge of deep soil moisture was faster in cropland(15 mm/a), but at this rate it would still take about 40 years to restore cropland soil water content to pre-plantation conditions.

结果表明，人工林死后的放牧荒坡在20a的时间里，其土壤水分没有补偿；人工林死后的保护草地土壤水分有微弱恢复迹象，但年恢复速度在0.5～3.7 mm之间，以这样的速度恢复到持续放牧荒坡的土壤含水量，至少需要150a以上；林后农地土壤含水量有恢复趋势，年平均恢复速度为15 mm左右，其土壤含水量要恢复到持续农地当前的水平，大约需要40a的时间。

Just like a red, blue, or white lotus — born in the water, grown in the water, rising up above the water — stands unsmeared by the water, in the same way I — born in the world, grown in the world, having overcome the world — live unsmeared by the world.

Field survey, sampling and testing were used to discuss the characteristics of soil water content between different subsidence stages. The results show that after mining collapsing, the soil water content and soil water storage capacity of subsidence area is obviously less than the nature area, especially for the fissure zone. It is indicated that the collapsing fissures are extremely disadvantageous for soil water-holding capacity and the conditions of vegetational cover on the subsidence area also confirmed this result.

现以神府东胜煤田为研究背景，选择两个主要塌陷阶段分布区大柳塔矿区双沟村原农场和补连塔矿区原补连沟村作为研究区，采用野外勘查、取样测试与室内参数分析综合研究的方法，对采矿塌陷不同阶段表层包气带土壤水分进行对比分析，结果表明，采矿塌陷后，塌陷区尤其是塌陷裂缝区的土壤含水量与土壤储水量值均小于未塌陷区，说明塌陷裂缝对土壤的持水作用具有非常不利的影响，塌陷区与未塌陷区的地表植被覆盖情况也证实了这一点。
