|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
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.
