摘要
野外实验研究表明，采矿塌陷作用不仅破坏包气带岩土结构，而且也改变包气带水分量状况和水势能状态；进而导致地表生态环境恶化，甚至出现土地沙化加剧的趋势。
The field experimental study manifests that. the mining collapsing action not only destroys the soilrock structure in the aeration zone, it also changes the water quantitative condition and the mode of water potentials in aeration zone. Thence it leads to the deterioration of the surface ecological environment, in as much as the increasing tendency of the desertification of the land.
