The Green Budget Model For Coastal Roads

Throughout history, the coastal regions of the globe have been major attractions. As a consequence, the world's coastal regions are densely populated and environmentally valuable. Coastal areas can be characterized by a diversity of natural features, processes and are often subjected to extensive development and a wide range of activities. Coastal roads are just one of the commonly seen activities. The construction and operation of coastal roads, however, implies the loss, degradation and fragmentation of habitats. Additionally, a time delay often exists between the damage and the mitigation of that damage, thus further aggravating the ecological injury. However, the present budget excludes these ecological losses. As a result, the government and the public have to bear the subsequent increasing investment. Therefore, a more sustainable budget system, or a"green budget"model should be established. A"green budget"model can thoroughly account for ecological loss and can make environmental investment more rational, which is different from the traditional budget system. In such context, I carried about the studies entitled"A green budget model for coastal roads"and major endeavors, detailed results are as followed.First of all, I tried to apply both the green budget system and ecological compensation principles to the coastal roads, and then built a green budget model. In this model, the green budget better reflects the utilization value of construction on resource capacity, and provides the necessary compensation for the impacts and damages caused to the ecosystem. In so doing, the construction will not only benefit from internalizing problems of uneconomical externality that may be caused by the behavior of a construction unit, but will also improve on the construction status quo of"polluting first and mitigating afterwards". Simultaneously, it further promotes the sustainable consumption of natural resources and ensures the protection of coastal zones.Secondly, references to current literature, relative guidelines and field studies, the ecological impacts caused by coastal roads were systematically analyzed and the ecological index was built. In the ecological index related to coastal roads, the terrestrial and marine impacts were not only identified, the common and particular ecological impacts were also explained. In this way, the ecological index well indicates the charaters of the coastal roads and the coastal zones.
