Abstract Cities develop in an excessive and disorderly way, losing their original characteristic identity and function. As a response to the deconstruction of the city, sustainable urban design came into being. This study evaluated the performance and sustainability level of Temuco community. The study was conducted in four sectors of the city, which are symbols and representatives of different stages of urban expansion. Through a set of urban design index standards including economic, social and environmental variables, the development of the community and the quality of life of its residents are evaluated. The results show that the Abraham Lincoln community has a better sustainability index, gathering a group that encourages sustenance and the availability of necessities nearby. The study found that new and old neighborhoods have deficiencies in neighborhood sustainability.

Abstract City biodiversity is an important part of global biodiversity conservation, and city biodiversity conservation needs to start with measurement and criteria. This paper introduces the Singapore index and Japanese index, and also introduces city biodiversity index conceptual framework which is developed based on the “driving force pressure status impact response model”. The trend of city biodiversity index development is pointed out to build a city biodiversity index of different scales, to build cooperative and shared information infrastructure and to evaluate city biodiversity index itself. At the end, in view of the status quo of city biodiversity index in China and the requirements of urban development, this paper proposes the conception of city biodiversity index development in China from the perspectives of local urban biodiversity, ecosystem service functions and urban management measures.

Abstract An important part of the construction of ecological civilization is ecological governance, which is an important way to promote the healthy and sustainable development of economy and society. Based on the DPSIR conceptual model, an evaluation index system with 30 indexes is constructed to empirically evaluate the state of ecological governance in Hunan Province from 2006 to 2015. The evaluation results show that the overall level of ecological governance in Hunan Province shows an upward trend. In each subsystem, the development trend of driving force, state, impact and response subsystems is getting better, the development trend of pressure subsystem is getting worse, and the pressure on ecological governance is gradually increasing. Based on the research results, this paper puts forward countermeasures and suggestions for ecological governance in Hunan Province from the aspects of politics, economy, culture and society.

Abstract Urban research related to sustainability is going through a rich experimental stage to explore different methods to deal with the current and future impacts of climate change on cities. This poses new challenges to the redevelopment of urban areas. These challenges are particularly relevant at a time of major urban transformation in the global south. This paper aims to develop a method to explore and evaluate the sustainable potential of urban morphology in the surrounding areas of medium-sized cities. The method involves six criteria related to the sustainability of built environment: scale, accessibility, diversity, connectivity, density and node. This approach applies to a community in Temuco, southern Chile. The results show the importance of building adaptive capacity to generate use diversity, which in turn promotes greater sustainability of urban morphology. On the other hand, the high population and housing density in residential areas reduce the pedestrian capacity of indoor streets, while the vertical mixed use and the change of urban block density are still the best response to promote social interaction and high collective activities in urban space. This paper summarizes the operational value of this method and reflects on the progress made in promoting the more sustainable urban form development of medium-sized cities in southern Chile in the future.

Abstract This paper selects 13 evaluation indexes of ecological civilization city construction level in 9 counties of Longnan City, processes the index data by using entropy weight TOPSIS method, calculates the closeness of ecological civilization city construction level in each county, makes an overall ranking of ecological civilization city construction level in each county, and then analyzes the ranking results, in order to provide theoretical guidance for ecological civilization construction in Longnan City.

Abstract Based on green development theory, green industrial system and green competitiveness, this paper puts forward the “green development theory, green industrial system and green competitiveness evaluation”. This paper makes a horizontal comparative analysis of the actual development data of Tianjin, Beijing, Shanghai and Chongqing, and verifies the scientific, standardization, systematisms and rationality of the “green model” evaluation index system. Using the measurement method combining fuzzy analytic hierarchy process and entropy method to determine the index weight of the evaluation system, this paper makes an empirical study on the green development competitiveness of Tianjin from 2011 to 2016, and analyzes the development status and existing problems of Tianjin’s green development competitiveness. Finally, aiming at the problems and weaknesses such as the lack of green social management function and the worrying overall quality of green environment in Tianjin, the paper puts forward countermeasures and suggestions to speed up the planning of green development demonstration area, make efforts to make up for the shortcomings of green environment, optimize the development strategy of industry city integration, build a smart ecological green city, publicize the concept of green development city and encourage the public to participate in green behavior.

Abstract In order to explore the development of ecological city in Shangluo City, principal component analysis and evaluation index system are used to analyze the overall development level, coordination degree of various subsystems, development level and influencing factors of Shangluo ecological city construction, in order to provide constructive suggestions for regional development and planning of Shangluo City. Research shows: From 2005 to 2015, the construction of Shangluo eco city showed a trend of differentiation, with good economic and environmental development, while the social construction developed slowly, and the economy, society and environment could not develop harmoniously. In the process of building a good, coordinated and unified ecological city in Shangluo, we need to be based on reality, develop strengths and avoid weaknesses, maximize the healthy and efficient development of economy and society in Shangluo, and better take the road of sustainable development.

Abstract Ecological civilization city evaluation is the driving force and main means to promote the construction of urban ecological civilization. The establishment of evaluation index system is the key to the scientific and accuracy of ecological civilization city evaluation. The element structure method is adopted to build the evaluation index model according to the functions of urban government in economy, culture, society and environment. Build an evaluation index system for urban ecological economy, ecological culture, ecological society and ecological environment.
