Abstract

China is facing an increasing urbanization in the edge area surrounding main metropolises. This paper targets at analyzing the construction mechanism of land use planning near suburban college towns. Theories and methods such as typical case analysis, mathematical model, and space capacity analysis were used to quantify the mechanism. A typical suburban block, Zijingang Campus Town of Zhejiang University was taken as the case. Since the key index (floor are ratio) indicates the construction intension of a patch of land, it is necessary to examine its appropiate range. The analysis result shows that there are differences in architectural prosperity and urban function by means of several designs. According to the guidelines of urban master planning and urban detailed plan, the Appropiate Floor Area Ratio (AFAR) calculated and deduced based on Economic Floor Area Ratio (EFAR) and Max/Min Floor Area Ratio (MFAR) can be useful in ratifying land development intensity, predicting future tend and evaluating city planning projects.

Abstract

Some rudimentary researches on the design of urban spatial information from the viewpoint of foreigners were performed through the case study of Saga City, Japan. By means of questionnaire survey, on-site investigation and route-searching experiment, the present condition, especially the problems of the urban spatial information for the behavior of foreigners were analyzed and grasped, and some principles of the design of urban spatial information considering the behavior of foreigners were proposed, which could be regarded as the extension of the concept of universal design. The results of the research can not only provide the basic data for the design and improvement of urban spatial information, but also can help to enlarge the concept of universal design by considering the factor of foreigners in wider fields.

Abstract

In this paper, we firstly put forward the conception of residential lifestyles; and suitably questionnaire surveys were conducted in two cities of Japan- lowland city Saga and non-lowland city Kitakyusyu. Through the analysis of the questionnaire data, we got hold of the characteristics of residential preference patterns, residential emphasis on dwelling selection, as well as the evaluation on residential environment satisfaction. Furthermore, the comparison between the two cities helped to make clear the similarity and difference of the residential emphasis between lowland city and non-lowland city. The results of the research will not only be benefit to the understanding of the diversification of residential lifestyles, but also provide more information to the planning and developing of residential environment effectively and efficiently by understanding the residential preference, emphasis and demands of various patterns.

Abstract

Although much research exists on whether public open spaces are satisfactory with respect to users‘ perception, designers often neglect residents‘ preferences before a project is to be authorized. Especially when they design daily used open spaces that are located near or inside residential areas, the value of spatial environments is not paid enough attention to. This study applies the Analytic Hierarchy Process (AHP) to a field survey in order to compare the residents‘ perspectives concerning three general attributes (functional, aesthetic and ecological) and ten specific qualities of daily used open spaces. AHP is a methodology that assists respondents to make subtle trade-offs in unquantifiable attributes by means of measuring the relative preference of one attribute over another. Although this methodology is entirely different from other choice-based methods considering the cost-efficiency, the results of AHP offer a systematic method to examine the demands of those unheeded people. The results of the AHP application into data collected from the Chinese residents find that public preferences for daily used open spaces are stronger for the functional attribute, rather than the aesthetic attribute in the ancient Chinese tradition. Furthermore, comparisons of ten specific qualities show that the public prefers the open spaces that can be utilized conveniently and easily for group activities, because such spaces keep an active lifestyle of neighborhood communication, which also is seen to protect human-regarding residential environments.

Abstract

Measuring complexity of the dynamic system has become a common practice for describing spatial structural properties in the fields of urban geography and landscape ecology. In China, college campuses can be regarded as a kind of complex system since the campuses accommodate multiple functions, such as education, research, leisure, residence and so on. Considerably diversified human activities are daily performed in campus open spaces. How to characterize the distribution dynamics of daily activities calls for much attention of architects and planners. Nonetheless, the resultant dynamics of human activities is often irregular and patchy, giving rise to intricate distribution patterns that can be difficult to characterize. Herein, the issue of characterizing the temporal-spatial-categorial Diversity of Activity Distribution (DAD) in open spaces was addressed and a method of quantifying the complexity of patchy activity dynamics was proposed. The method was inspired by information-based measures of entropy, and the proposed Behavioral Entropy Index (BEI) can distinguish the distribution of activities in open spaces between simple (convergent) and complex (random) temporal-spatial-categorial mosaics. The method was demonstrated using sample data through a survey on two typical college campuses at Hangzhou City, China. The results show that the BEIs effectively illuminate the behavioral dynamics, rather than the conventional index of absolute population or simple percentage; moreover, proper facilities, natural environments and campus management all facilitate improving the behavioral complexity.

Abstract

In this research, waterside spaces of a lowland city were studied from the interactive aspect of physical conditions, users’ consciousness/behaviors, and waterside design. Firstly, using Saga City as a case study, the overall conditions of waterside spaces in the city and their physical properties were made clear through site surveys. Then, by Semantic Differential (SD) survey and analysis, three main image components of waterside spaces in urban open spaces and residential environment of lowland cities were found: natural view, environmental arrangement, and urban density. Next, through Cluster Analysis, five image types of waterside spaces and their characteristics were obtained. Furthermore, the behavior tendency of each type of waterside was also analyzed. Finally, on the basis of above surveys and analysis, environmental designs were performed in the five types of waterside, and a SD simulation was conducted to verify the effectiveness of the design. The effective reformation methods for different types of waterside spaces were discussed in order to improve the image of waterside and to activate users’ behaviors. The results of this research could be applied directly in the development and improvement of waterside spaces for practice.

Abstract

Residential environment is one of the most important elements for quality of life, as well as the main support for the activities of economy, culture and society. On the other hand, the improvement of residential environment quality also has been increasing the consumption of energy and emission of pollution. In this paper, we established a systematic methodology for the evaluation of sustainable residential environment, considering both residential environmental quality (Q) and residential environmental load (L). The part of Q is constructed by safety, healthy, amenity, convenience and community of residential environment. The part of L is about the environmental impact of the lifecycle of the housing and community. We hope the results of our study can contribute to the sustainable development and improvement of urban residential environment for rapidly developing China.

Abstract

The rapid urbanization of Chinese cities has been resulting to the degradation of urban residential environments. As a representative of green areas, residential open spaces play key roles to balance the needs for both conservation and development. Traditional ways to observe resident’s behavior mode only by calculating the absolute population count is not perfect. In order to achieve the goal of public benefits, this study attempts to develop traditional behavior approaches to establish an unconventional determinant factor to enable the examination of temporal regulation, spatial distribution and activity category of residents’ behavior through the Behavior Entropy Index (BEI). Through this study, the author hopes to provide recommendations to interrelate the local view into planning process. The data was collected in 6 different residential areas and 4 campuses in Hangzhou. In sum, the result obtained from the study aiming to not only satisfy residents’ desire of the improvement of open space but also bring to professional’s attention by examining the diversity of user’s behavior in the context of residential open space utilization and finding out physical factors which influence their satisfaction and behavior. The samples can be hopefully extended to reasonably represent the overall situation of Yangtze River Delta and provide a valuable reference for other regions of China.

Abstract

Soundscape is a new interdisciplinary field of landscape and acoustics. This paper is intended to study the relationship between soundscape and culture. That is, the Chinese culture’s pursuit of acoustic beauty from three aspects as poetries, writings and drawings. It is demonstrated by the case study of soundscape in West Lake scenic area, with particular emphasis on humane attribute. The study has approached by three steps as classification - case study - promotion to region. The major attractions of West Lake scenic area is divided into natural and artificial categories, and the typical cases selected are “Orioles Singing in the Willows” and “Evening Bell Ringing at Nanping hill.” The two cases are analyzed from two aspects as the cultural background and humanities artistic conception, in order to prove the subject. And the importance of soundscape culture research to the construction of West Lake scenic area is declared further.
