| 中文摘要 |
| 采用3种不同栽培方式,受试木本植物16种、草本植物9种,在垃圾填埋场进行营造人工植被的试验。结果表明,填埋场甲烷气是影响植物成活的主要因素。在填埋1-2年的废弃地上,栽培短周期生长植物全部成活,获得了预期效果。在埋龄1年的垃圾废弃地上不易种植长周期生长的木本植物,在埋龄2年的废弃地上,仍需采取覆盖60cm土层阻断沼气等措施才能生长。筛选出抗性较好的植物枸杞、苦楝、紫穗槐、刺槐、白蜡树、女贞、苜蓿、画眉草、牛筋草和知风草等十几个品种。 |
| 英文摘要 |
| An artificial ecosystem of vegetation was rehsbilitated with 16 species of xylophyta and 9 species of herb&ceous herb by using three different techniques of cultivation on a waste land fill site. The results showed that methane given out of the landfill site was a main factor affecting the rate of vegetation survival. On a land fill site where the refuses hsve been dumped for 1 to 2 years, the desired resultS were obtaind for planting the vegetation of a short6r growing Period. The Species of xylophyta having a longer Period of growth were not suitable to be planted on a discarded refuse landfill site of 1 year and could be planted on a 2 year discarded refuse land fill site only by covering an earth layer of 60 cm thick to break methane given out. The species of plant which have a higher tolerance have been screened as follows: Lycium chinensis Mill., Melia azeclarach L., Amorpha fruticosa Linn., Robinia pseudoacacia Linn., Fraxinus chnensis Roxb., Ligustrum Lucidum Ait., Medicago sativa L., Eragtrostis pilosa, Eleusine india, Eragrostis Ferrngiea Beanv. |
