摘要:
城郊绿色基础设施兼具城乡生态 服务与游憩功能,孤立或对立审视此二功能 会导致过度开发或机械被动保护,有机融合 则会促进城郊自然环境资源的高效保护与利 用。结合文献研究与案例分析,论文详细阐 释了融合生态服务与游憩功能的绿色基础设 施用地规划理念及技术方法:一、目标定位, 融合资源保护、生态服务、游憩休闲等复合目 标;二、现状分析,甄别绿色基础设施用地 保护要素与空间格局;三、功能设置环节,因 地植入维护要素系统自然生态过程的游憩功 能;四、用地组织层面,带动游憩产业发展的 同时提升其支持、供给、调节、文化四大生态 功能服务水平。

Planning Research for Suburban GI Land-Use System on the Perspective of Introducing RecreationPursuit into Ecological Service Function—A Case Study of Mindong Non-Development Land Planning, Meishan City

Abstract:
Green infrastructure (GI) is the material and spatial carrier of ecosystem services. The ecological service function of GI is based on the ecosystem service function. Being different from traditional protection strategy, GI is a method that integrates a series of concepts such as environmental protection, urban and rural development, infrastructure planning and smart growth into ecological protection, meeting all kinds of interests as well. The GI land-use spatial pattern reflects a certain degree of construction characteristics on the premise of ecological protection, concerning both protection and utilization. Furthermore, suburban GI land-use system includes not only the vast area within the urban development boundary and the surrounding ecological green space, green wedge and important ecological corridor outside the urban centralized construction area, but also relatively scattered construction plate, village space, infrastructure land and so on. The GI land in urban fringe area constitutes the background part of the urban periphery space, providing important ecological services and supports for the city, showing a highly integrated edge effect of human activities and natural processes, and profoundly affecting or restricting the development boundary, spatial pattern and environmental quality of urban-rural area. From the perspective of human needs, the GI land-use system plays an important role in both ecological services and recreational supports. Ecological service function, as the basic value of GI land, is the endogenous motive force for the healthy development of recreation system. The implantation of recreation function reflects the value-added benefits of GI land. Isolating or opposing these two functions will lead to over exploitation or mechanical passive protection. On contrary, organic integration will help the development of ecological and spatial resources utilization with the premise of protection, and promote the sustainable and healthy development of urban and rural environment. Under the guidance of this systematic thinking, highlighting the ecological service function of GI in urban planning and construction and reflecting the value-added benefits of recreational function are of great research value and practical guiding significance. Based on the concept of implementing actively for the protection and utilization of GI, integrating the natural, social and economic processes carried by land-use and spatial layout,realizing the symbiosis and co-prosperity of environmental protection and urban construction, integrating the economic links of urban land-use with ecological protection and construction, shaping the social and cultural links with regional environmental characteristics, is conducive to improving the comprehensive benefits of urban and rural eco-economic-social links. By methods of literature research and case analysis, this paper elaborates on the concept and technical methods of GI land-use planning, which integrates ecological services and entertainment functions: 1) Target positioning, integrating resources protection, ecological services, recreation and leisure and other composite objectives; 2) Present situation analyzing, identify the protection elements and spatial pattern of GI; 3) Function setting, implant functions which adopt to natural factors to maintain natural system's ecological process; 4) Land-use organizing, improve the four ecological functions of support, supply, regulation and culture while promoting the development of recreation industry. Faced with the contradiction between the protection and utilization of GI land in suburbs, the fundamental objective of land-use system planning is to realize the protection and utilization of natural resources in suburbs, and to integrate the four ecological service and recreational functions of GI land: 1) The ecological support function is based on the protection of resources and space, identifying the overlapping areas and relatively independent areas of the two major functional areas of ecological support and recreational services, dividing the ecological support protection areas and recreational areas, protecting the ecological support protection areas in the form of large patches and corridors, and arranging the recreational sightseeing zones around them; 2) On the premise of guaranteeing production function, ecological supply function catalyzes green industry in nonconstruction areas, builds agriculture-nature park relying on forest and fruit and special planting areas, and forms a landscape pattern of agriculture and forestry suitable for agriculture and tourism; 3) The key function of ecological regulation is to maintain the green corridor-patch space system, in addition, to form a river-pond-lake flowing water system in the hilly area, and to introduce moderate recreational activities relying on core ecological resources; 4) The function of cultural service should be combined with the distribution of cultural relics and landscape resources. Landuse planning should make full use of the original towns and villages, construct the theme park around the city, service and infrastructure space system, and improve the environmental quality as well as economic and social benefits of GI land. Integrating the four basic benefits of ecological services and the value-added benefits of recreational functions of GI land is one of the important methods to organize suburban GI land-use system. It is also an important way to promote the benign interaction between natural processes and human activities, maximize the efficiency of protection and utilization of natural resources, and ultimately realize the sustainable and healthy development of urban-rural area.
