Research On The Recreation Security Pattern Of Ah-cheng District In Harbin

With the Chinese urbanization entering a new stage, better standard of living conditions are making people transferring to recreation space to get rid of tired daily work. Much more need and stronger intention to get close to the nature guiding us to accelerate the construction of recreation spacesystems. China is rich in recreation resources, however, the defects of existing management system lead to the problem of uneven distribution, simple type, single function of recreation space, and the lack of communications between different spaces. The conventional planning of recreation spaces and paths in China is mainly in the perspective of human that is lacking in the ecological security protection and sustainable development which lead to hidden danger of environmental disruption and safety threat. Therefore, we need further study about security patterns of recreation spaces.As part of the research in ecological security patterns, recreation security patterns is aiming at providing people with recreation spaces to relax, which also refer to direct influence of experience quality. In this context, this paper takes Ah-Cheng district which located in the city of Harbin as object, using theories about landscape ecology, ecological infrastructure, recreation spaces and evaluation methods to form the evaluation systems of recreation securitypatterns in Ah-Cheng. Finally, with the support of GIS technology platform, we get the recreation security patterns of Ah-Cheng together with planning guide to guide construction.In this paper, we take evaluation about Ah-Cheng’s recreational region and trail. Recreation regionsuitability is evaluated under multifactor weighted superposition scoring methods which included AHP method and Delphi method. Recreation trail suitability is calculated under the minimum cumulative resistance model. With spatial data analysis of GIS, we get therecreation security patterns of Ah-Cheng. The next stage is putting forward the planning guide about HS, MS and LS level and in the perspective of recreational region,trailand recreation infrastructure. The construction could satisfy people’s recreation need and meanwhile ensure the security patterns of ecological sustainable development.
