Welcome to Volume 5, Issue 1 of Eco Cities. This issue will present research how cities deal with environmental pollution and climate change. These articles propose innovative solutions for governing urban environments and addressing climate change, and some of these solutions make use of advanced technologies such as the Internet of Things, thereby contributing to the improvement of urban environments, management, and residents' quality of life.

Volume 4, Issue 2 highlights how cities overcome numerous challenges to achieve sustainable development. The three most important factors influencing urban sustainable development are urban transportation, the environment, and population. This issue proposes various solutions, such as improving travel planning and utilizing digital technologies, to mitigate the impact of the mentioned problems on urban sustainable development. And analyzing the factors that influence urban sustainable development can provide useful information for urban managers' decision-making, effectively advancing city sustainability.

This issue will explore how to solve problems in urban governance from new perspectives. Innovative research tools and perspectives, such as artificial intelligence technology, edible landscapes, and the positive impact of the COVID-19 pandemic, have been shown to significantly improve urban operations and development. In addition, this issue also includes research on improvements to urban infrastructure and the challenges it faces, providing useful information for relevant researchers.

Volume 3, Issue 2 focuses on the evaluation and construction of eco-cities, as well as urban sustainability. Exploring the assessment system of ecological cities and the path of ecological city construction can provide useful recommendations to urban planners and improve city livability levels. Furthermore, this issue highlights the importance of ecology in urban sustainable development and investigates promising urban development models to aid in achieving urban sustainable development.

Volume 3, Issue 1 offers readers an exploration of how to protect and improve urban ecology from novel research perspectives, emphasizing the importance of biodiversity conservation. To tackle urban ecological problems, this issue discusses strategies for protecting and restoring the urban ecological environment, as well as the factors that influence it. Furthermore, the application of artificial intelligence technology provides fresh ideas for scholars conducting urban ecological research.

Welcome to Volume 2, Issue 2 of Eco Cities. Continuing with the topic from the previous issue, this issue presents a compelling discussion of urban sustainable development from various viewpoints, including factors impacting urban sustainable development, such as urban green space, and strategies to promote urban sustainable development, such as the application of urban meteorology. 

Volume 2, Issue 1 focuses on research into the evaluation of urban ecological civilization construction and introduces the development and implementation of an evaluation index system for ecological civilization cities. The application of the ecological civilization city evaluation index system allows for a comprehensive understanding of the level of urban ecological civilization construction, fostering its development. In addition, this issue provides an assessment of urban sustainability and an investigation of urban biodiversity indexes. This issue thoroughly analyzes and evaluates the development state of cities, offering valuable information for the development of ecological civilization cities.

Welcome to Volume 1 Issue 2 of Eco Cities. All of the scholars in this issue are from China, and they offer readers eco-city research with Chinese characteristics. This issue focuses on the construction, development, and evaluation of eco-cities, as well as the analysis of the development condition of China's eco-cities in terms of economy, society, resources, and the environment, which indicates the bottlenecks and directions of its development. The assessment of eco-city construction from a low-carbon perspective is the issue's highlight, as it delves thoroughly into the features and current state of China's eco-city growth.

Welcome to Volume 1, Issue 1 of Eco Cities. This issue will offer readers five high-quality articles, including the most recent investigation into China's urbanization development path, the construction eco-city, a comparison of the characteristics of eco-city development, the dilemmas faced by urban development, and the relationship between urban development and law. These studies go over the principles of ecological civilization and sustainable development, summarize the bottlenecks of urban growth, and make useful recommendations for the development of eco-cities.
