Abstract
The Pinglu Canal is the first artificial canal since the founding of the People’s Republic of China following the Beijing-Hangzhou Grand Canal. It is a major pioneer project for many national strategies, and bears great construction significance. Attractive natural landscape and ecological environment, and abundant tourism and cultural resources along the Pinglu Canal have raised a higher environmental requirement for its construction. In this study, the impact of the planning route of the Pinglu Canal on overall landscape pattern is analyzed from several aspects such as number of patches, mean patch area, largest patch index and fractal dimension. Besides, the impact of multiple routes of some sections on landscape pattern is compared for appropriate route selection. The suggestions for environmental protection strategies of canal construction are proposed from the perspectives of the protection and restoration of ecosystem, as well as the integration of tourism and culture. The results will provide references for landscape pattern impact analysis and ecological protection countermeasures for the constructions of other canals.
