Some of China's major cities have entered the middle and late stages of urbanization, and the development focus of these cities has gradually shifted from outward expansion to inward renewal. The community, as the basic unit of a city, is undoubtedly the main object of urban renewal. In order to efficiently and effectively address the problems in current community construction, it is necessary to conduct a large-scale in-depth assessment of the community livability, which can directly imply the satisfaction of residents with their quality of life. This study achieved the first comprehensive livability assessment at the individual community scale for 42 major cities of China from the perspective of remotely sensed and crowd-sourced geographic information. Specifically, we produced abundant fine-grained datasets for 42 cities, including high-resolution land cover maps interpreted from Ziyuan-3 satellites(ZY-3, 2.1 m), building height, point-of-interest, and boundaries of 101,630 *** designed in our proposed framework, the community livability was evaluated by 5 level-1 indicators, 27 level-2 indicators and an integrated community livability index(CLI). A number of interesting findings were obtained from this assessment:(1)According to the expert questionnaires, living comfort was considered as the most important livability factor for residents with the highest weight, while the building environment was rated the least. The negative factors(e.g., the factories around the community) impacted more on livability than the positive ones.(2) Most communities in major Chinese cities were characterized by dense buildings and sparse green spaces.(3) In these cities, community security construction was severely insufficient,particularly in less developed regions.(4) Imbalanced community livability development was prevalent across cities, and simultaneously, the CLI distribution within cities also exhibited significant spatial aggregation and heterogeneity.

Journal of Landscape Research 2019年第4期11卷 39-45,50页

作者： GAN Lu CHAO Heng YANG Yi School of Urban Planning and Design Peking University Shenzhen Guangdong 518055 China Laboratory for Urban Future Peking University (Shenzhen) Shenzhen Guangdong 518055 China China Vanke Co. Ltd. Shenzhen Guangdong 518055 China

Abstract The rural region is an important spatial unit for rural revitalization and urban-rural integration in the new era, strengthening the livability study has important practical significance for guiding the hard environment construction of rural regions. The evaluation index system of livability perception of residents in rural regions was constructed. Based on the questionnaire survey and in-depth interview of Doumen Town of Zhuhai City, this paper revealed the livability characteristics of rural residents and its influencing factors. The research showed that:① Residents of rural regions were quite satisfied with natural environment and built environment, but less satisfied with public service and infrastructure, and showed the social differentiation in livability perception;② The livability perception evaluation of rural residents was significantly affected by livable factors, showing the decreasing characteristics of “public service factors>social and humanistic environment factors>infrastructure factors>built environment factors>natural environment factors”;③ Individual and family attributes of rural residents were also important factors affecting their livability perception, but less important than the livable factors.

Evaluation on livability of Urban Residence Based on RS and GIS——A Case Study of Shihezi City of Xinjiang Province

引用

Journal of Landscape Research 2010年第9期2卷 56-59页

作者：奚秀梅朱凤军王玲石河子大学师范学院地理系新疆石河子832003

By selecting environmental amenity,living convenience,and living health as the primary indexes as well as park,school,supermarket,main urban traffic road and industrial district as secondary indexes,the livability of urban residence in Shihezhi City was evaluated based on spatial analysis method of RS and GIS technology and the most suitable sites for residence was located,so as to provide references for future planning and construction of Shihezi City. The study showed that:in accordance with the benefits and harms of residential environment to residents,the livability of urban residence in Shihezi City could be graded into seven degrees;the most suitable site could be found in the area between Beiyi Road and Beiwu Road to the east of Xihuan Road,which was close to school,supermarket and park,and was the most ideal residential area in Shihezi City.

Improvement Strategies of Flood Control Landscape in Suburban Villages and Towns from the Perspective of Aquaphilia and livability

引用

Journal of Landscape Research 2022年第6期14卷 40-42,46页

作者： DING Huangjie YAN Chen FANG Cheng ZHANG Shijie LV Yuanhao College of Landscape Architecture and Art Fujian Agriculture and Forestry UniversityFuzhouFujian 350108China Research Center of National Water Park FuzhouFujian 350108China Fujian Urban and Rural Planning Design Institute FuzhouFujian 350000China

In the context of urban and rural integrated development, many suburban villages and towns are still threatened by both urbanization and natural disasters. In order to explore the improvement strategies of flood control landscape integrating water ecology, water safety, water culture and water landscape, the Luozhou Ancient Town by the Wulong River in Fuzhou City was taken as an example, and the concept of pluralistic symbiosis from the perspective of aquaphilia and livability was proposed through field investigation, data monitoring, site analysis and planning, that is, while retaining the positive attributes of “boundary”, its negative limitation of “pluralistic” space is broken, so as to establish a pluralistic and symbiotic environment with aquaphilia and livability. It can not only effectively alleviate the contradictions between urban and rural areas, between water and land, and between old and new cultures, but also activate the vitality of suburban villages and towns, providing a new idea for the improvement of flood control landscape.
