Abstract

Abstract: Taking "China and Indochina Peninsula economic corridor" as a case, with the support of GIS technology, this study analyzed the spatial pattern of road network and its impacts on landscape ecological risk. The results are showed as follows. 1) The effects of road network on landscape pattern were related to the landscape types, among which the impervious surface was affected the most. 2) There were obvious spatial differences in landscape ecological risk throughout the whole study area, and the risks in China and Thailand were relatively higher than those in the other countries. 3) There was a certain correlation between road network and landscape ecological risk. As the density and level of road increased, landscape ecological risk presented an upward trend accordingly. The above results suggest that the corresponding road construction and planning strategies should be developed for different regions and landscape types.

Key words: road network, landscape, ecological risk, China and IndoChina Peninsula economic corridor
