Study On Responding Organism Of Highway Domain Ecosystems And Ecological Functions Regionalization

As the significant component of modern transporting system, highway is the basic andpioneering industry of National Economy, and after the Tenth Five-Year Plan, the constructionscales have been multiplying, and its construction areas are advancing for mountainous regions.Generally speaking, the longer of the highway, the more complex ecology bypassed, the moreimpact and destroying caused. The data says, the areas impacted by highway construction havebeen up to from fifteen to twenty percent, and eighteen percent in our country as well.So, that carrying out ecology protection policy and coordinate the contradiction betweendevelopment and ecology to gain the sustainable development of regional ecology becomes to bethe urgent issues.In this paper, some theory of ecology, highway domain ecology, structures and functions werereviewed, and the purposes, the principles, the methods were clarified, and the ecologicalaffections were discussed thoroughly. Then the changing features of structures and functionswere investigated based on background investigation and current investigation, finally, theecology responding organism were established. Besides, this paper will attempt to apply theconcept of ecological functions regionalization, and type-matching table was set up. Furthermore, the highway domain ecosystems were divided into two advanced eco-zones, threeeco-zones by dominating index method.
