The invention discloses a cargo stowage calculation method based on cargo distribution site, cargo volume and vehicle type, which is characterized by comprising the following steps of: S1, inputting all available vehicle information including vehicle types, vehicle quantity upper limits corresponding to the vehicle types, and loading spaces of the vehicle types; S2, screening out the vehicle typecapacity with the size or weight larger than the maximum vehicle type capacity, and removing the vehicle type capacity from the intelligent combination list for manual processing; S3, ranking the vehicle types in a descending order according to the vehicle type ranking volume, and outputting a vehicle type ranking sequence L (L = {1, 2, 3... t}) and the corresponding vehicle upper limit number K1(l = 1, 2, 3... t); and S4, inputting distribution area information A (A = {1, 2, 3... m}) and all non-combined DO order information D (D = {1, 2, 3... n}), wherein the DO order information comprisesthe volume Vd, the weight qd and the destination da. By means of positioning information of goods and navigation software, attributes of various goods, vehicle load and the like, the stowage rate andthe average kilometer benefit of the single vehicle are improved by analyzing early-stage configuration data and depending on a reasonable stowage algorithm.
