Effects of road on landscape and its ecological risk assessment:A case study of Lancangjiang River valley

Abstract

Abstract: Road and road networks bring forth many ecological effects,as they run through all kinds of landscapes,while road ecological risk analysis is to comprehensively assess various potential ecological effects and their accumulative effects trough pattern and process research.Focused on the impact of roads on landscape,the road effects were divided into construction period and passage period,with two indexes based on different effects on pattern and process to describe the effects put forward and the comprehensive ecological risk index deduced.Taking three case areas at upper,middle,and lower reaches of Lancanjiang River valley as examples,this paper analyzed that the road impact on landscape,and calculated their ecological risk index.The results indicated that though ecological risk distributed differently in each area,road density had high positive linear correlations with risk indexes.

Key words: Plantation, Litterfall, Nutrient, Nutrient translocation
