Mountain Demarcation In The Ecological Space Protection Of Mountainous Cities

Mountain,water,forest and farmland are the main ecological elements in mountainous cities that is closely related to the ecological civilization construction of the city.There is a complex relationship between them that are interdependent and stimulate each other,which make them an ecological community.As the core ecological elements and ecological resources distribution space of mountainous cities,the mountain contains rich ecological properties,economic properties and cultural properties.In addition to being able to highlight mountain city features,and playing a decisive role of stability of water,land,forest,but also guiding the formation of urban and rural construction pattern that corresponds to ecological environment,on the basis of ecological space protection.At present,the definition of space to the mountain or in the protection of ecological space with regional geomorphology perspective of overlooking the earth from the air to delimit the basis,such as the height above 500 meters above sea level,the cutting depth is more than 100 meters become mountain etc,but ignored the people living in the mountain of intuitive feelings;In addition,the structural relationships and ecological and biological processes in the mountains often result in the lack of difference and operability in the definition and protection of mountains.Aiming at this problem,this article from the cognitive rules of cognitive science to the real space and landscape inspired,through analyzing the domestic and foreign research on space method as defined in the mountain and experience,use of geomorphology,landscape ecology,ecosystem ecology theory research results,related to parse mountain space structure form and function and correlation of the process,put forward and follow the human perspective "follow hydraulic mountain" the concept of logic,using GIS spatial analysis techniques,to delimit the ecological significance of mountain structure space,its main content includesReference to the cognitive laws of spatial cognitive science,combined with the comprehensive research achievements of landscape,both at home and abroad clear mountain space is defined to reflect the characteristics of the material in mountainous region and ecological structure space mountain(the ridge lines,valley lines,the bottom line,and the top of the mountain)defined;Use and ecosystem ecology of physical geography landscape process and biological ecology research,identify the mountain space itself contains the attribute structure,functions and ecological characteristics,the material energy flow process;Furthermore,with the formation mechanism of water space,ecological function and process as the guidance,combining with the study area mountain,water,settlement,the relationship between digital top model(DEM)as medium,in geographic information system(GIS)as technical support,extract and water ecological space corresponds to the mountain space structure.The method makes up for the current in the ecological protection on mountain the defects of insufficient space cognition,from the viewpoint of geomorphology and ecology to cognitive and delimit the mountain space,space for urban and rural ecological protection provides a theoretical support and practical basis,promote the ecological planning in the guidance of urban and rural ecological civilization construction of the improvement of the system and method.
