By analysis of sampled soil physical properties,compared that with bare area,the results show that: there is no certain change pattern between soil bulk density and soil porosity;the bulk of soil bulk density gets larger and the soil gets deeper,while the soil bulk density gets smaller at certain depth and the capability of sluice falls.
以徐州市三环路内4个城区的公园绿地土壤为研究对象,通过对其土壤的物理性状取样分析,同时与无植被覆盖的裸地进行对比,结果表明:该城区公园绿地土壤容重与孔隙度随时间无确定的变化规律;该土壤容重开始随土壤深度增加而减小,某一深度以后逐渐增加,而土壤孔隙度随土壤深度增加而增加,某一深度以后逐渐减小,土壤蓄水保水能力降低。

本文论述了成都、合肥、南京、襄樊和安康裂隙粘土的发育和分布特征，并通过大量的室内试验详细讨论了裂隙倾角、裂隙数量和隙壁粘土厚度对土体力学性质的控制作用。
补充资料：孔隙水
| 孔隙水 pore water 主要赋存在松散沉积物颗粒间孔隙中的地下水。在堆积平原和山间盆地内的第四纪地层中分布广泛。是工农业和生活用水的重要供水水源。孔隙水的分布、补给、径流和排泄决定于沉积物的类型、地质构造和地貌等。不同成因的沉积物中 ，存在着不同的孔 隙水 。在山前地带形成的洪积扇内，近山处的卵砾石层中有巨厚的孔隙潜水含水层；到了平原或盆地内部，由于砂砾层与粘土层交互成层 ，形成承压孔隙水含水层 。在平原河 流的中 、下游地区的河床 相的砂砾层中，存在着宽度和厚度不大的带状孔隙水含水层。在湖泊成因的岸边缘相的粗粒沉积物中，多形成厚而稳定的层状孔隙水含水层。在冰川消融水搬运分选而形成的冰水沉积物中，有透水性较好的孔隙水含水层。深层孔隙承压水往往远离补给区。离补给区越远，补给条件越差，补给量有限，故深层孔隙承压水的开采应有所节制。 |
