Quality evaluation of low carbon ecological city based on development stage—Take Shandong Province as an example

The exacerbation of climate change impacts within metropolitan areas is a well-documented phenomenon, often leading to severe consequences that pose significant risks to human populations. The impact of urban vegetation and planting design on these factors can be observed. However, it is worth mentioning that while there is an extensive body of literature on the consequences of climate change, there is a relatively small number of studies specifically focused on examining the role of vegetation as a mitigating factor in urban environments. This review paper aims to critically examine existing studies pertaining to the role of urban vegetation in mitigating the detrimental effects of the urban environment. The objective is to offer practical recommendations that can be implemented by city planners. By conducting a comprehensive examination of the literature available in Scopus, Web of Science, and Google Scholar, employing specific keywords pertaining to urban vegetation and climate change, we have identified five prominent concerns pertaining to the urban environment. These concerns encompass particulate matter, gaseous pollution, noise pollution, water runoff, and the urban heat island effect. The present analysis highlights that the impact of urban vegetation on the negative consequences of climate change cannot be unequivocally classified as either positive or negative. This is due to the fact that the influence of urban greenery is intricately connected to factors such as the arrangement, makeup, and dispersion of vegetation, as well as the specific management criteria employed. Hence, this research has the potential to enhance comprehension of the multifaceted nature of urban green spaces and establish a solid groundwork for subsequent investigations.

Analytical study on the coupling coordination degree of tourism and urban development—Taking Shaanxi as an example

Tourism has been instrumental in fostering regional economic growth, enhancing the quality of life of residents, and boosting the image of urban areas in Shaanxi, thanks to the accelerated economic and social development of recent years. Nevertheless, the issue of aligning urban development and tourism in terms of space, resources, and the industrial chain remains a significant concern. This paper establishes an evaluation index system for tourism and urban development in the Shaanxi region from 2009 to 2019. It then employs the systematic coupling coordination model to conduct a comprehensive analysis of the coupling coordination degree of tourism and urban development in the region, as well as its various influencing factors. The study demonstrates that the coupling and coordination degree of tourism and urban development in the Shaanxi region exhibited a trend of continuous improvement from 2009 to 2019. The region underwent three stages of development: “uncoordinated development (2009–2011), transformation development (2012–2016), and coordinated development (2017–2019).” The coupling coordination level was elevated from “mild dissonance” to “intermediate coordination” in 2019. In contrast, the tourism economic development of Shaanxi cities remains unequal, as evidenced by the existence of two distinct categories of development: the “lagging tourism economy” and the “coordinated tourism economy.” The findings of this investigation indicate that the general trend of urban development and tourism in Shaanxi is favorable; however, the disparities in the progress of the tourism economy among cities necessitate additional regional coordination and cooperation. The theoretical support for the relevant research and a reference basis for tourism development planning and urban policy making are provided by the evaluation index system and the systematic coupling coordination model proposed in this paper. This will facilitate the sustainable and coordinated development of the tourism industry and cities in Shaanxi.

Abstract

Aiming at the problems existing in the current evaluation of low-carbon ecological city, based on the comprehensive interpretation of the scientific law of the development of low-carbon ecological city, this paper distinguishes the path index and evaluation index, constructs the evaluation index system of low-carbon ecological city according to the evaluation index, adopts the quadrant method, establishes a set of technical methods for the evaluation of low-carbon ecological city based on the development law and development stage, and makes an empirical analysis with Shandong Province as an example. The results show that Shandong has crossed the peak of the inverted U-shaped curve of carbon emission intensity, but it is still in the rising period on the left of per capita carbon emission and total carbon emission; According to the situation of each city, there are 10 cities of high-carbon development type. Most cities have entered the critical period of low-carbon ecological transformation and development. The high low-carbon index of some cities has a great relationship with the low level of economic development, and they are in the primary development stage of low-carbon and low economy.

Eco-cities are becoming a reality!

In the context of eco-city development, the term "eco-city" encompasses a multifaceted ecosystem characterized by the interdependence of natural, social, and economic systems. This concept emphasizes the need for sustainability through environmental friendliness, social equity, and economic growth. Various models of eco-cities, including garden cities, green cities, and landscape cities, reflect the ongoing exploration of achieving harmony between humans and nature in urban living environments.
