Abstract: The characteristics of logistics distribution under the B2C e-commerce modes were analyzed，the vehicle routing problem with time windows under the consideration of carbon emissions was described，a routing optimization model with time window was built up. The integration of GIS technology and Tabu-search algorithm was applied to solve the model. The logistics distribution routing optimization system under the B2C e-commerce modes was developed. A preliminary application study of the system was carried out on the logistics distribution data from an e-commerce enterprise in Xiamen. The results showed：there was still large space for carbon emissions improvement in the arrangement of traditional distribution routes；the integration of GIS technology and Tabu-search algorithm not only realized the better decision making of distribution routing optimization，but also provided assistant analysis to the decision makers.
