Dongjiang river is the source of drinking water of Guangdong Province and Hongkong, and the source area includes three counties in Ganzhou city of Jiangxi Province: Xunwu, Anyuan and Dingnan. Three typical villages were chosen in Dongjiang river source area to investigate the producing quantity and physical characteristics of rural solid waste. Results of investigation showed that the dominant ingredient in rural solid waste in Dongjiang river source area was kitchen waste, taking over 60%, followed by dust, reaching 12%, while other components took less than 10%. The per-capita producing quantity of solid waste of county-level village was 0.2~0.47 kg·d -1 and averaged by 0.36 kg·d -1, while that of town-level village was 0.18~0.35 kg· d -1, averaged by 0.29 kg· d -1 and that of hamlet was 0.07~0.33 kg· d -1, averaged by 0.17 kg· d -1. Water content in rural mixed solid waste of investigated area was significantly linear with percentage of kitchen waste in the mixed waste(R 2 =0.626, P=0.019). The average calorie wasaround 2 329 kJ·kg -1, which indicated that the rural solid waste in Dongjiang river source area was not suitable for incineration disposal directly.
