摘　　要：调查和分析了国内外城市园林绿化废弃物资源化处理方法和工艺,结合中新天津生态城城市发展理念和区域特点,提出了适合本地区园林绿化废弃物资源化利用可行性方案,建议如下:将绿化废弃物分为难降解和易降解两大类。第一类经粉碎、灭菌、压缩或降解,生产栽培基质、生物质燃料和生物炭。第二类经粉碎、好氧堆肥发酵制得有机肥料或厌氧发酵生产沼气、沼液和沼渣。两类废弃物输出产品为绿色能源和土壤改良剂,实现了城市绿化产业“取之园林,用之园林,变废为宝”可持续发展的目的。This article makes an investigation and analysis of the domestic and foreign landscaping waste resource treatment methods and processes.Combined with the urban development concept and regional characteristics of Sino-Singapore Tianjin Eco-city,a feasible plan for the resource utilization of landscaping waste in this region was put forward.Suggestions are as follows:garden waste is divided into two categories:those difficult to degrade and those easy to degrade.Waste of the first category is crushed,sterilized,compressed or degraded to produce cultivation substrates,biomass fuels and biochar.Waste of the second category is used to produce organic fertilizer by crushing and aerobic composting or biogas,biogas liquid and biogas residue by anaerobic fermentation.The output products of the two types of wastes are green energy and soil improver,realizing the sustainable development goal of the landscaping industry of"taking the waste away fromthe garden,turning the waste into treasure,and using the waste in the garden".
