In the research, cultural landscapes in Zhangjiajie National Forest Park were surveyed and evaluated to analyze characters of cultural utilization, as wel as problems existing in the Park. In addition, highlights were given to protection on cultural landscapes in a forest park construction, presentation of ethnic minority culture, and ful development of tourism products.展开更多

In the proposed algorithm, a primary path is dynamically divided into several segments according to the differentiated reliability requirements of the customers. In the SPP-DiR algorithm, the whole primary path should be protected, while in the DSSP- DiR algorithm, only partial segments on the primary path need to be protected, which can reduce more backup bandwidths than that in the SPP-DiR algorithm. Simulation results show that the DSSP-DiR algorithm achieves higher resource utilization ratio, lower protection failure probability, and shorter recovery time than the SPP-DiR algorithm.展开更多
