项目摘要

In Asian mega-cities, large-scale landfills have been constructed for these mega-cities in order to meet the needs of disposing of large amounts of municipal solid waste (MSW) discharge. In a landfill, it is important to monitor a stabilization degree of landfilled MSW. In a large-scale landfill, however, there are high costs and much manpower involved in such monitoring. Moreover, present methods of landfill monitoring, which are made at several points at a frequency that seems appropriate to the investigator, has difficulties in statistically extrapolating results and deducing quantitative results for the whole area. Especially, due to the inhomogeneous properties of landfilled MSW, it is difficult to understand the situation of the entire landfill by limited information acquired from point surveys.Satellite remote sensing (SRS) is one of the methods that can solve above noted problems. For example, SRS can provide vegetation data with spatial distribution on a landfill. Though there are some studies that vegetation characteristics on a landfill site is affected by landfilled waste, the detail mechanisms of interaction between the vegetation and landfilled waste have not been clarified.In order to find out the relationship between the stabilization degree of landfilled MSW and the vegetation characteristics on a landfill site, the author carried out following investigations ; landfill gas monitoring, cover soil and landfilled MSW samplings and vegetation surveys at the Laogang Landfill in Shanghai, which is one of the largest landfill in China. Results indicated as follows;(1)after the landfill completion, vegetation began to grow where water content of cover soil was high, (2)the landfill gas concentration decreased where vegetation existed and permeability of air was high because of the effect of roots, and (3)a stabilization degree of landfilled MSW under bare area was later than that under vegetation area.

在亚洲大城市，为了满足处置大量城市固体废物（MSW）排放的需要，修建了大型垃圾填埋场。在垃圾填埋场中，监测填埋垃圾的稳定程度非常重要。然而，在大型垃圾填埋场中，这种监测成本高、人力多。此外，目前的垃圾填埋场监测方法是在几个点上以调查人员认为合适的频率进行监测，在统计上推断结果和推断整个区域的定量结果方面存在困难。特别是，由于填埋垃圾的不均匀性，仅靠点调查获取的有限信息很难了解整个垃圾填埋场的情况。卫星遥感（SRS）是解决上述问题的方法之一。例如，SRS 可以提供垃圾填埋场空间分布的植被数据。虽然已有一些研究表明垃圾填埋场植被特征受到垃圾填埋场植被特征的影响，但植被与垃圾填埋场相互作用的具体机制尚未明确。上海老港垃圾填埋场是中国最大的垃圾填埋场之一，该填埋场的垃圾填埋气体监测、覆盖土壤和填埋垃圾采样以及植被调查。结果表明:(1)填埋场建成后,覆盖土含水量较高的地方开始生长植被;(2)由于根系的作用,有植被且空气渗透性较高的地方填埋气浓度降低;(3)裸露区填埋垃圾的稳定程度晚于植被区。
