- Abstract:
-
There has been increasing interest in studying ecosystem impacts of road projects. Studying ecosystem suitability concepts showed that ecosystem suitability stressed by road projects which mainly studied the proper degree of road projects effecting on ecosystem according to ecosystem structure and function stability was a converse to ecological effect study. Ecosystem suitability could be expressed as differences among variable succession and road projects constructions phases in temporal scales and differences of ecosystem attributes and the road building properties in spatial scales by analyzing its attributes and characteristics. And its key problems included identifying its threshold quantity and establishing indices system and assessment model. Comparing road project intensity with the ecosystem stability can identify the ecosystem suitability threshold quantity. Ecosystem suitability assessment indices system will be established through electing indices including road project intensity, ecosystem and its response using AHP methods. The assessment theory model based on three basic hypothesizes provides fundamental basis for quantizing ecosystem suitability.
