Abstract:

The construction of Ya'anKangding highway has great significance on the establishment of the economic corridor from Sichuan province to Tibet Autonomous Region.It also has great importance on the opening and development of the region from Ganzi Tibetan Autonomous Prefecture to the whole Tibet area. Since the highway will pass through the buffer zone of the world natural heritage of Sichuan giant panda sanctuaries(SGPS),it may have negative impacts on the SGPS in the processes of construction.It is necessary to clarify the potential influences of the construction to the SGPS,in order to handle the relationship between the highway and the world natural heritage protection appropriately.Based on the field investigations,interviews and profile maps on the relationship between the highway and the heritage,the potential influence of the highway on the SGPS was analyzed.The results showed that the highway would not have direct impact on the authenticity and integrity of the SGPS.However,it would cause obvious disturbance to the natural landscape by the geological engineering exploration of the Er'lang Mountain tunnel and the construction and maintenance of the ventilation shaft groups.Several measurements for the highway construction were proposed to protect the world natural heritage of SGPS
