With its rapid development, the rural area of Southwest China has been puzzled by the waste management problem, especially for increasing solid waste and water pollution from the domestic waste. Therefore, in order to efficiently and effectively manage the domestic waste in the rural area of Southwest China, 22 villages were selected randomly to analyse the characteristics of domestic waste, the influence factors of characteristics and resident's willingness of participation in domestic waste management by questionnaires, field samplings and laboratory tests. The results of the rural area of Southwest China indicated that the generation of domestic waste was 178 g d(-1) per capita and it was mainly composed of kitchen waste, inert waste, plastics and paper with a total proportion of 81.98%. The waste bulk density, moisture, ash, combustible and lower calorific value were 107 kg m(-3), 37.04%, 25.73%, 37.23% and 8008 kJ kg(-1), respectively. These characteristics were influenced by the topography, the distance from towns or cities, the villagers' ethnicities and income sources to some extent. Moreover, the distance of 50-800 m between each collection facility and the disposal fee of around ¥5.00 per household per month could be accepted. The working hours of participation in waste management is suggested as 5 hours per day with the income of ¥1000 per capita per month. Based on the outcome of this survey, a waste management system consisting of classified collection, centralised treatment and decentralised treatment was proposed. It is important to ensure financial viability and practical considerations of this system.
随着中国西南部农村地区的快速发展，该地区一直受到垃圾管理问题的困扰，尤其是生活垃圾产生的固体废弃物增加和水污染问题。因此，为了高效、有效地管理中国西南部农村地区的生活垃圾，通过问卷调查、实地采样和实验室测试，随机选取了22个村庄，分析生活垃圾的特征、特征的影响因素以及居民参与生活垃圾管理的意愿。中国西南部农村地区的调查结果表明，生活垃圾人均日产量为178克，主要由厨余垃圾、惰性垃圾、塑料和纸张组成，总占比为81.98%。垃圾的堆积密度、含水率、灰分、可燃成分和低位热值分别为107千克/立方米、37.04%、25.73%、37.23%和8008千焦/千克。这些特征在一定程度上受到地形、与城镇或城市的距离、村民的民族和收入来源的影响。此外，每个收集设施之间50 - 800米的距离以及每户每月约5元的处理费用是可以接受的。建议参与垃圾管理的工作时间为每天5小时，人均月收入为1000元。基于本次调查结果，提出了一个由分类收集、集中处理和分散处理组成的垃圾管理系统。确保该系统的财务可行性和实际可操作性很重要。
