Based on the analysis of the arrangements of current inland berths of China，this paper puts forward a new layout of the inland compound harbor basin，in which the ships’ turning area will not occupy the main channel，and the layout of the berths are compact. We may build this new compound harbor basin，especially in the situation that the land width is limited，the number of berths is large，and the main channel is busy. Compared with the arrangements of current inland berths，the new compound harbor basin has more advantages，which may serve as a reference for the site selection.
