城市防灾避险绿地系统的构建

城市防灾避险绿地系统构建是城市绿地系统规划的重要内容。宏观上要在城乡总体规划的框架内,在城市抗震防灾等规划的指导下,构建与城市绿地系统规划空间层次相互衔接、逐级控制的防灾避险绿地规划体系;中观上要根据避险时序及空间关系等要素,对避险绿地、绿色疏散通道、隔离缓冲绿带等各级防灾避险绿地进行定量定位的合理布局;微观上要对每一块避险绿地、绿色疏散通道、隔离缓冲绿带进行深入与细化设计,共同构筑结构合理、层次清晰、分布均衡的城市防灾避险绿地体系。     

Planning Overall Landscapes,Building a Garden City:on the Revision of Guangzhou Urban Green Space System Planning

The concept of urban green space system planning was proposed after analyzing the background of compiling Guangzhou green space system planning and current situation of local green spaces,i.e. design landscape pattern of Guangzhou City during urban agglomeration of the Pearl River Delta,and highlight Lingnan cultures(Lingnan refers to south of the Five Ridges) and features of Flower City(another name of Guangzhou). Key points of planning are protecting ecological barriers in the north,improving urban garden structure in the center,using wetland reasonably in the south,to maintain integrality and continuity of the landscape pattern.     

Ecological Coupling Theory and the Method System of Urban countryside Space Planning

Since P. R. China has experienced extensive land resource use, environmental degradation, lagging rural development and other difficulties in 20th century, urban countryside integration and ecological planning has become an important subject to build a harmonious society in the 21st century. The country attempted to use complexity science and ecological thinking based on recognizing the relationship between the city and countryside and raising the city countryside space ecology coupling concept to construct a city countryside space planning methods system consisting of the identification of urban and rural land uses, urban and rural non construction land planning, city countryside coupled environmental conditions assessment, coordinated city countryside space development and city countryside space system fractal optimization, and more.     

Research on Ecological Space Planning Oriented Urban River Landscape Planning

Based on the generalized landscape perspective, regional connotation of urban river landscape is expanded. The area connotation of urban river landscape is expanded based on the generalized landscape perspective. In addition to natural and functional attributes, river landscape should be regarded as a regional space element based on heterogeneous space scale. First, as for research method system, the space research models(including ecological footprint, space planning, and landscape pattern index, etc.) coupled with different angle scales and interdisciplinary theory, are utilized to study different correlations and results formed by urban river landscape elements and other regional space elements from the perspective of the regional ecological space, and the overall development goal of the urban river landscape pattern based on the goals of the regional ecological space planning is obtained. Second, the oriented urban river landscape planning and the M type close-tonature design strategy are evaluated through the city function zoning orientation and micro-scale urban river landscape pattern index. The research realizes the compatibility of overall goals in terms of the regional ecology, the development of urban functional areas, and the river landscape planning, without losing micro difference and maneuverability based on the urban river landscape planning and design oriented strategy, which innovates the new approach of urban river landscape planning and design with sustainable and balanced development of regional resources, multi-scale, and multiple objectives.     

Ecological Construction of Urban Green Landscape in Chongqing City

The urban green landscape in Chongqing was analyzed from the view of landscape ecology. It was believed that the urban green landscape was developed rapidly in recent years, but there are still some problems existed, including mainly: (1) the structure of green landscape was unreasonable, (2) the quality of green patches was low, and (3) the function of green corridors was incomplete. It is pointed out that in some urban regions there were lack of green patches, furthermore, some patches were isolated from each other due to lack of green corridors. In the last, taking account of the foundational theory about patch and corridor, some aspects for the design of urban green landscape in Chongqing were proposed: connecting the river and road green corridors and increasing the green patches at the ecological strategic points.     

On Green Lighting Planning and Design of the City

The energy-conserving environmental protection and the culture characteristic protection are two themes to the sustainable development of modern city,and the green lighting project is an important condition to ensure sustainable development of the city.But now,in some lighting projects the energy consumption and economy power capability were ignored;some design tactics are identical and in the green lighting projects the whole lighting of the city was not considered,which cause the crisis of losing the city characteristic.This paper proposes the green view of city lighting planning,and points out that the energy conservation,environmental protection,economic feasibility and culture characteristic must be considered synthetically in the city green lighting planning and design to guarantee sustainable development of the city.     

Planning and Ecological Landscape Design of Urban Constructed Wetland

Social and Psychological Benefit of Urban Green Space

Recent rapid urbanization has broad impact on the contemporary urban environment. Preserving the natural environment has become the central issues in the world. The main concern of this paper is to address the importance of social function of green space. Some results of a survey conducted among visitors of urban parks in Mianyang city in Sichuan Province are presented and discussed. The results confirm that open space experiences have a positives influence on psychological and mental health. Urban green space verifies beliefs about stress-reduction benefits and mental health, and advances social intercommunication. Finally, the monetary evaluation methods of urban green space, such as contingent valuation method, hedonic pricing method, travel cost method, are discussed.     

Relations between Urban Design and City Planning in the Work of Plan-making

In this paper, three fundamental principles of city planning under the present system are brought forward: the integration of urban design and city planning, the double attributes and position of the urban design and the correspondence between the urban design and the city planning in levels. Therefore, according to the different circumstances, three functioning ways for the urban design in the practice of plan making are put forward: to put the urban design into the system of city planning, to work out the urban design as a research work and then make use of its achievement in the work of plan making, and to regard the urban design as a specialized work of city planning.     

城市绿地系统社会服务功能及其评价研究综述

城市绿地系统社会服务功能所具有的重要价值已在世界范围内引起了人们的普遍关注,有关城市绿地系统社会服务功能及其评价的研究也取得了较大的进展。但通过文献综述发现,这些研究对城市绿地系统社会服务功能与城市绿地的规划、建设、保护和管理之间的相互关系探究极少且深度不够,使得这些研究的实践意义不大。而在有关城市绿地系统社会服务功能评价的研究上,也存在着诸如评价指标少且未形成体系、研究范围较窄、研究的深度和广度不够等不足,以致不能真实、综合地反映出城市绿地系统多元的社会服务功能。为此,为了全面、客观地反映出城市绿地系统社会服务功能所具有的价值,应坚持综合性、层次性、独立性,可操作性、易获得性等原则,并构建定性与定量相结合的指标体系。
