Study On Suburban Recreational Landscape Design Based On Farmland And Water Pattern

Dujiangyan water conservancy project shape Chengdu agricultural civilization and the unique characteristics of rural landscape in Chengdu area, under the Chengdu modern garden city construction background, large tracts of suburban open space with huge potential ecological, recreational value, bear the city an important ecological services and social service function. It is need to consider the inheritance, remodeling ecological and humanistic value of place in the suburban recreational landscape design, in order to service society more sustainably. At the same time, the author participated in the Chengdu city eco-green project design program in the Sichuan Institute of Architectural Design during the professional practice time, the author found that the "map" of recreation space and the "bottom" of farmland-water network can not effectively coupled design, and can not effectively protect and utilize farmland-water network. Therefore, the author analyze the farmland-water pattern from the perspective of landscape ecology, combine with the current needs of social recreation, and explore landscape design strategies and methods in outskirt of a city to achieve sustainable development of suburb environment about production, ecology and recreation.Firstly, this paper use the theories of landscape recreation and landscape ecology, combine with domestic and foreign related theories and cases, analyze constituent elements of the Chengdu Suburb traditional farmland-water network pattern from the perspective of landscape ecology. This paper use the method of landscape pattern index, comparative analysis characteristic changes of landscape pattern from 2002 to 2014, analyze the status of the landscape changes in the suburban area from the perspective of patch-corridor between graphic and landscape pattern index angle; Secondly, through the design project and farmland-water network coupling of landscape pattern analysis to discuss the recreational landscape design’s rationality and applicability; Finally, this paper put forward the recreation landscape design strategy based on farmland-water pattern.In this study, the author analysis the Chengdu suburb farmland-water network pattern from the perspective of landscape ecology, found that suburban landscape basal farmland water network structure facing fragmentation, and functional degradation. Combined with the actual case of ecological green space around city analysis and demonstration, patch corridor pattern diagrams and landscape index PD, ED, MPS has guiding role in the analysis of disturbance condition of the project design and the farmland water network, and has important significance on suburban landscape ecological oriented construction. Among them, at the macro level, the suburban landscape under the protection of the development goals is the direction of Chengdu suburban landscape construction; At the meso level, through the "bottom" of the spatial pattern recognition, adjust and optimize the original farmland water network, according to recreation intensity to delineate the region different attributes, the recreation space design strategy suitable for all kinds of space is the critical approach to realize the effective protection and use of farmland water network; At the micro level, that the ecological and local design of suburban landscape elements is an important part of the formation of suburban recreational node, corridor image.
