The Study On Coordination Of The Division Of Space Regulation And The Division Of Ecological Protection

With the speed of industrialization and urbanization more and more fast,the extensive development leads to ecological system is simpler and more fragmentend.This style of regional economic development cause these problems,such as:the environmental problems,the reducing function of ecological system.Moreover,the ecologcial security pattent ensures that the regional ecological security and ecological security of sustainable development was not formed.Nowadays,the Urban ecological system planning,environmental planning,afforesting planning and other planning planed the ecological planing in different levels and perspetctive division from the perspective of different levels.These plannnings are based on the analysis of regional ecological factors to plan the regional ecological system is not consider about the process of ecology.Therefore,this article summarizes the progress of domestic and overseas studies on ecological red line.Evaluating the importance of ecological function and the importance of ecological sensitivity bases on the process of ecology.Ecological red lines are those regions the most important ecological and the most important ecological sensitivity.The controls of these regions are base on the regions and its kind.There are many kinds of planning systems because of overwhelming administration.There all kinds of planning are repeating and conficting each other all the time,but no path of coordination and institutional arrangements between all kinds of planning.These formal systems are hard to avoid conflicting policies from different departments.Summarizing the progress of domestic and overseas studies on the coordination of plannning systems and basing on coordination in pratices and analysling the concept,connotation,delimit method draw a conclusion that some regulations.It exists"guidence and feedback" and "division and complementarity" in these regutions.Basing on the principle of "functional regionalization" and "ecology first" gives "two planning" coordinating scheme and refactoring "two planning" space division.Xi'an's ecological region identified by the method of ecological red lines and controled by different of ecological protection eares.Basing on the method of Xi'an's ecological region puts forward "two planning" spaec division:"the most importent ecological area" "the more importent eare" "the strict limited of construction land" "the generally limited of construction land""the district of history""basic farmland reserves""suitable building area"in area.Putting forward "two planning" space division:“the most importent ecological area" "the more importent eare" "the slimited of construction land" "suitable building area" "buit-up area”as well as "four Lines" in downtown district.
