Abstract: Taking 8 kinds of main vegetable wastes in 11 prefecture-level cities of Hebei Province as study
object，the paper estimated the quantity of different vegetable wastes resources in Hebei Province by grassgrain
ratio．The results showed that the quantity of vegetable waste resources in Hebei Province increased at
an average rate of 42 600 t · a^-1 from 2011-2016，reaching 2.30 million t in 2016．Among which，cabbage
（578 700 t），Chinese cabbage（434 200 t） and solanaceous vegetables（299 800 t） had the highest quantity
of vegetable waste resources，increasing by 100.98%，50.80% and 4.12%，respectively compared with
the mean value，followed by tubers，beans and melon vegetables．Those of leaf and bulb vegetables were
the lowest．The quantity of waste resources was distributed unevenly among each prefecture-level city，
with 50.57%-82.52% coefficient variation．Tangshan（408 100 t），Shijiazhuang（351 700 t），Baoding
（297 800 t） and Zhangjiakou（279 600 t） had the maximum quantities，accounting for 58.04% of the whole
province．Utilization as resource manure of all these vegetable wastes in the province was equivalent to indirect
application of 45.15 kg · hm-2 pure nitrogen，27.75 kg · hm^-2 pure phosphorus，44.85 kg · hm^-2 pure potassium
and 1 089.15 kg · hm-2 of organic matter per 667 m2 farmland；and equivalent to 6.68% of the annual amount
of chemical fertilizer and 2.992 million t of organic fertilizer，among which cabbage，Chinese cabbage and
solanaceous vegetables had the highest nitrogen，phosphorus and potassium nutrients，accounting for 57.73%
of the 8 kinds vegetables．The organic matter content in tubers vegetables was the highest．The quantity of
vegetable waste resources in the whole province showed a steady upward trend from 2011-2016．There were
significant differences in the quantities of all kinds of vegetable wastes and nutrients in different regions，among
which vegetable yield and waste coefficient had become important factors affecting the difference of vegetable
waste resources quantities．
