Despite increased attention given to potential modifiers of temperature-mortality associations, evidence for variations between different urban landscape characteristics remains limited. It is in this context that in this paper effect modifications of multiple urban landscape characteristics are explored under different heatwave definitions for different age groups and gender in Hong Kong, China. Daily meteorological data and heatwave-related mortality counts from 2008 to 2017 were collected from the Hong Kong Census and Statistics Department, China. A case-only design was adopted, combined with logistic regression models to examine the modification effects of five urban landscape characteristics under six heatwave definitions. Stratified analyses were conducted to investigate age- and gender-specific effect modifications. It is found that individuals living in greener areas experienced lower levels of mortality during or immediately after heatwaves. In contrast, a higher building density and nighttime land surface temperature (LST) were associated with a higher heatwave-related mortality risk. Pronounced effect modifications of these urban landscape characteristics were observed under hotter and longer heatwaves, and in older adults (age ≥ 65 years) and males. The findings provide a scientific basis for policymakers and practitioners when considering measures for coping with hotter, longer, and more frequent heatwaves in the context of global climate change.

The urban landscape heterogeneity has been influenced by the visual, unpleasant and unacceptable face of which there is no charm in it. The present study is formed according to visual pollution and its impact on the appearance and vitality of a city. Preliminary studies and theoretical studies led to the hypothesis with the following themes: 1) There is relationship between the pollution, heterogeneity and visual disturbances urban landscape and urban vitality;2) Improving the quality, aesthetics and identity of public spaces will increase urban vitality. Therefore, the design process within the theoretical principles, concepts, television and urban landscape, urban art, visual pollution aspects (color, light, and visual symbol) and the quality of urban vitality and explain causal relationships, analytical framework developed and more samples case (garden historic town of Maraqeh1) and the area under study were selected using GIS. After designing the questionnaire to evaluate the objectives, assumptions and questions of research and its analysis, the results indicate that the relationship between visual pollution and urban vitalitys, as well as proving hypotheses and vitality after the final analysis, model was introduced based on the components of comfort visual editing and proposed at three levels: micro, middle and macro for objectives, strategies and policies to regulate visual pollution and improve the aesthetic quality of the environment and the promotion of vitality.

The rapid expansion of urban construction land has become the major characteristic of urban land-use change in China today. Meanwhile, the rapid urbanization process has led to the great changes of urban landscape in China, and it also has had certain impacts on environmental factors such as climate, soil, hydrology, biodiversity, etc., then it has made the overall ecological environment deteriorated. This study is based on the summary and analysis of research on land-use change and ecological environment effect of urban landscape in recent 20 years in China, and it aims at providing scientific bases and theoretical supports for the planning and construction of urban landscape, the sustainable land-use of city and the protection of ecological environment in China.

Composition and Value Orientation of urban landscape

引用

Journal of landscape Research 2017年第1期9卷 80-82,86页

作者： YI Yongqing LI Jianzhen Institute of urban Ethics Hunan City University Yiyang Radio and Television University

Based on the analysis of the urban landscape and its composition,main problems of urban landscape at the early stage of urbanization were summarized,including more attention to the technical content of urban landscape,valuing transformation but belittling protection,emphasizing uniformity,ignoring the diversity,lack of scientific planning,and neglecting the value orientation. It is expected that the construction of urban landscape may return to its aesthetic value,practical value,ecological value and other aspects of value orientation. It is believed that the urban landscape is both a type of perception and experience. It can not only maintain the cultural heritage and the evolution of civilization,but also maintain the integration of the biological and physical environment,play the role of diversification in the urban public open space,and undertake social functions such as ecological,disaster prevention,waterlogging,and water conservancy at the same time of protecting and lighting the environment.

The effect of texture and irrigation on the soil moisture vertical-temporal variability in an urban artificial landscape： a case study of Olympic Forest Park in Beijing

引用

Frontiers of Environmental Science & Engineering 2015年第2期9卷 269-278页

作者： Xiaofeng ZHANG Xu ZHANG Guanghe LI School of Environment Tsinghua University Beijing 100084 China

Soil moisture variability in natural landscapes has been widely studied; however, less attention has been paid to its variability in the urban landscapes with respect to the possible influence of texture stratification and irrigation management. Therefore, a case study was carried out in the Beijing Olympic Forest Park to continuously monitor the soil in three typical profiles from 26 April to 11 November 2010. The texture stratification significantly affected the vertical distribution of moisture in the non- irrigated profile where moisture was mostly below field capacity. In the profile where irrigation was sufficient to maintain moisture above field capacity, gravity flow led to increased moisture with depth and thus eliminated the influence of texture. In the non-irrigated sites, the upper layer （above 80 cm） exhibited long-term moisture persis- tence with the time scale approximating the average rainfall interval. However, a coarse-textured layer wea- kened the influence of rainfall, and a fine-textured layer weakened the influence of evapotranspiration, both of which resulted in random noise-like moisture series in the deeper layers. At the irrigated site, frequent irrigation neutralized the influence of evapotranspiration in the upper layer （above 60 em） and overshadowed the influence of rainfall in the deeper layer. As a result, the moisture level in the upper layer also behaved as a random noise-like series; whereas due to deep transpiration, the moisture of the deep layer had a persistence time-scale longer than a month, consistent with characteristic time-scales found for deep transpiration.
