Turn Brownfield into Green Space-Eco-Regeneration of Closed Landfill
With the accumulation of solid waste in developing countries, sites of closed landfills have attracted attentions, which can be sorted as one typical brown field in urban area. Taking closed municipal solid waste landfills as examples, case study for turning brown land into green space in Europe and USA was carried out, based on which, suggestions on the ecological regeneration of brown land in China were put forward. It was put forward that for closed landfill constructed in the earlier days, the reliable procedure for the site generation should be reclamation. If it is not possible to carry out the reclamation engineer at present, establishment of trees on the top soil of closed landfill, in other words, eco-regeneration can reduce the negative effects of landfill as far as possible. For the developing countries, reduction, stabilization and recycling of solid waste should be the final solution for solid waste.
