The contradiction between the shortage of parking space and the incr easing number of motor vehicles is still growing in the recent years. The utiliz ation of various kinds of mechanical parking facilities is an effective solution to this problem. How to organize a reasonable logistics system in a mechanical parking lot so that as many parking positions as possible can be constructed wit hin a limited space at the lowest cost is a long challenging subject for enginee ring designers. Obviously, it is of great value to approach this subject theoret ically and systematically. Based on the study of the development of different me chanical parking facilities, the features, definitions, classifications and eval uation indexes of mechanical parking logistics systems are discussed in this pap er.

The undertaking of a SWOT analysis of such a framework is necessary because it enhances the efficacy of IAS control. The aim of this study is to carry out a SWOT analysis of the policy framework guiding the control of the spreading of Acacia mearnsii and other IAS in the Golden Gate Highlands National Park in South Africa,as well as the implementation of restorative measures in the park and adjacent communities in line with the recommendations of the Convention on Biodiversity. A comparative analysis of this framework and the hierarchical framework that was developed during the European Union Conference on Freshwater Invasives- Networking for Strategy in 2013 is undertaken. The results indicate the need to strengthen parkcommunity relations,upgrade existing legislation,and boost the technical capacity of South African national parks to identify,detect,monitor and predict IAS invasions,both within the parks and their surroundings. This knowledge is important for developing future policies on IAS control in South Africa.展开更多
