| 摘 要： | 研究并探讨了腾发覆盖垃圾场覆盖不同植物、土质和厚度调节对覆盖层控制渗沥的作用。4组腾发覆盖试验结果表明,腾发作用在覆盖层控制渗沥水过程起关键作用,无植物覆盖处理的实际利用土壤水库容量能力仅相当于植物覆盖的65%,无植物覆盖的60 cm覆盖层的储水能力与有植物覆盖40 cm覆盖层的储水能力基本相当;植物生长是覆盖层水均衡和渗沥控制的关键因素。在腾发作用强烈的夏秋季,渗沥水控制效果明显,然而在冬季,仅依靠覆盖层储水能力控制深层渗沥,则需要较大的覆盖层厚度。

| Abstract: | Use of an evapotranspiration landfill was studied,considering vegetation structures,soil textile,and soil cover thickness.Results of four experiments showed that the transpiration process played an importance role in controlling water balance in the ET cover system.The evaporation in the bare soil was 65% as that of evapotranspiration amount.In a 40 cm soil profile,Plant growth is a coating of water balance and seepage control of the key factors Lek.Role in the strong evapotranspiration in summer and autumn... |
