Aircrafts at aprons can be parked either by towing equipment （push-back） or by its own power （serf-powered parking）. The costs of these two methods for Maputo International Airport were investigated. Based on airplane parking design theory, formulas to calculate the annual maintenance cost at aprons were proposed. Calculation results indicate that self-powered parking is preferable, justified by the fact that this airport has low traffic volume. The system of aircraft parking adopted by this airport saves significantly the cost for purchase and subsequent maintenance of push-back.展开更多

The results showed that there are 76 tree species of 69 genera and 41 families in the park. According to the species diversity analysis, among the 5 subareas recreational area has the highest diversity and evenness indexes, zoo has lower diversity index of plant community. Three-dimensional analysis of plant community shows that the community has simple structures, limited landscape layers and shrub coverage, a few lawn species and poor landscape effect. Analysis of its ecological habits shows that evergreen species in all 5 subareas of the park are more than deciduous species, and there are only a few ornamental tree species.展开更多
