Establishing The Index System Of Ecological Enviornmental Monitoring Of Xanadu’s Grassland Cultural Relics In The Regional Development

Xanadu as grassland site of the most completely preservation in China,which has the value of history, art and conservation.Xanadu relies on the jinlianchuan grassland which not only is one of the world cultural inheritance,but also makes it become the symbol of the Mongolian culture. Due to the destruction of history and human beings, the grassland ecological environment drops down in both space and quality. Therefore,how to scientifically and reasonably construct Xanadu’s regional development of ecological monitoring index system is the key to the protection and inherit of grassland culture sites. This paper talks about theoretical analysis,the frequency statistics and expert analysis method which preliminary establishes the monitoring index system. And then uses the correlation analysis method, variation coefficient method and principal component analysis method for the sensitive factor screening. The final purpose is to establish the index system of ecological enviornmental monitoring of Xanadu’s grassland cultural relics in the regional development.The main conclusions are as follows:(1)Application each boundary delimitation and the corresponding landscape patch area proportion.It puts forward a dividing range which is based on historical record and natural geographic units.The protecting land range includes the Xanadu’s plain and the grassland together with the mountains around which is naturally formed.In the north,the boundary from the Dalai Lama Ovoo,Changtu Ovoo, the elevation of 1474m and the Large Ovoo to the Xanadu’s river dam,Double hill, North Fort and Zhenzi Hill,South Fort to Gurban Hada Ovoo, from the south the town as a starting point Geer Ovoo,Gagen Ovoo, Hulusitai Ovoo,Wula Ovoo and Chagan Ovoo connection Dalai Lama Ovoo from northern.Area of ecological environment protection of this classification is 55352.47hm2.(2)In the preliminary construction of monitoring index system, the index system of ecological enviornmental monitoring of Xanadu’s grassland cultural relics in the regional development as the target layer,historic site’s landscape, ecological system as the control layer,the landscape elements, landscape heterogeneity, plant, animal, air quality of the environment, soil, groundwater, surface water as element layer,which has 50 monitoring indicators.(3) Through the comprehensive analysis of the monitoring indicators,induction and selection these monitoring indexs which has the most sensitive to grassland ecological environment. Finally we set up the 31 indexs for the monitoring index system.(4) Establish the weight coefficient of the monitoring index system and show that the selected indicators and regional development has the very good correlation. Landscape has the same weight with the ecological system,but in the landscape,landscape heterogeneity is more important than that one.The maximum weight is water in the ecosystem,followed by the plant,soil,air quality of the environment and animal.(5) The definition of boundary and the construction of monitoring indicators are fully considering the feasibility and science and so on. As grassland cultural relics’s ecological enviornmental monitoring index system in the regional development,it has targeted, applicability and operability.
