Abstract

Abstract: Taking Jiangle County,Fujian Province as an example,forest landscapes were classified into 9 categories according to the dominant tree species.The forest landscape patterns and the changes of the forest landscape in different terrain factors were quantitatively compared in the road effect zone of 1 000m among the different grades of roads,such as provincial road,county road and village road in the same length.Results showed that the diversity level of the forest landscape in the provincial road was high at low altitude or shady slope,while the diversity level was high in village road in areas with high altitude or sunny slope.Fragmentation of forest landscape was serious in the low altitude or slope of village roads,the heavy fragmentation occurs at high altitude of county road.But fragmentation of forest landscape was the most serious in risk slope of provincial road.

Key words: road network, forest landscape, the terrain gradient, spatial pattern
