Abstract Directing at the problems of unclear resource base and unknown utilization direction of vegetable waste，this study explored the measuring and calculating method for building scientific and standardized vegetable waste production coefficient；specified the recommended value range of the coefficient；and constructed resource account of vegetable waste by taking Changping District of Beijing as an example．Researches indicated that the production coefficient of typical vegetables waste in Huang-Huai-Hai region was between 0.9%-10.7%；collectable coefficient was between 0.22-0.93．The moisture content at harvest was all above 80%．There were big differences among production coefficient，collectable coefficient and moisture content of different vegetables waste．Compared with the waste mainly vines of fruits，beans and jackets，the collection of leafy vegetable waste was more difficult．The theoretical resource amount of vegetable waste in Changping District of Beijing was about 14 800 t（fresh weight）and collectable amount was about 11 200 t in 2021．The comprehensive utilization rate of vegetable waste was about 55.39%．Market main body utilization proportion was over 90%．The amount of directly returning to field was about 8%，and amount of dispersed utilization by farmer household only accounted for less than 2%．The usage way was basically fertilizer utilization，accounting for up to 99.69%．To sum up，the main utilization method of vegetable waste removing from the field was fertilization in China and the overall reutilization level of was still relatively low．
