“…1). In this perspective, as long as the pressure is within the support capacity threshold, the coral island system can remain healthy and stable 35,53,54 . Herein, CORE-CC is defined as the combined threshold of resources supply, environmental capacity, ecosystem services, and socio-economic supporting capacity of the coral reef islands that could carry socio-economic activities without causing degradation of the structure and function of the social-ecological system.…”

“…The socio-economic supporting dimension refers to the ability of human socio-economic to improve the resources supply capacity, environmental assimilative capacity and ecosystem services capacity of the coral reef islands. Human socio-economic's support behavior includes research and development of more resources, pollution control, environmental construction, ecological protection and restoration construction, etc 35,54 . Its capacity depends on the level of socio-economic development and the degree of support for the sustainable development of coral reef islands 51,72 .…”

“…However, the ultimate comprehensive research results are difficult to judge whether the examined carrying capacity is overloaded 50 . Recently, many scholars believe that it is necessary to analyze the relationship between the support of the carrier and the pressure carried by the carrier to reflect the carrying capacity, so that the state of the carrying capacity can be more accurately judged [53][54][55] . But the evaluation objects are mostly single elements, such as water resources 53 , ecological environment 54 , etc., which can only provide partial understanding of sustainability 55 .…”

Coral reef islands provide precious living space and valuable ecological services for human beings, and its sustainability cannot be ignored under the pressure of human activities. Carrying capacity (CC) assessment has gradually become an important means to measure sustainability of islands. However, there is little comprehensive evaluation of the carrying capacity of coral reef islands, and traditional evaluation methods are difficult to express the social-ecological characteristics of coral reef islands. The present paper proposes a comprehensive assessment model for coral reef island carrying capacity (CORE-CC) which comprises dimensions of resources supply, environmental assimilative, ecosystem services, and socio-economic supporting. According to the characteristics of the coral reef islands, the core factors and indicators of each dimension are selected and the corresponding assessment index system of "pressure-support" is constructed. The assessment involves (1) identification of carrying dimensions and core factors, (2) pressure/support measurement and (3) assessment of carrying state. A case study is conducted in Zhaoshu Island of China, demonstrating the applicability of CORE-CC model and serving as a reference for adaptive management.

“…ITH the aggravation of global resources and environmental problems, global governments have attached great importance to studies of the eco-environment [1][2][3]. Especially in developing countries, the contradiction between rapid urban development and the fragile ecoenvironment has become increasingly acute under the background of urgent development requirements [4,5].…”

Urbanization and climate change cause the urban ecological environment to become increasingly dependent on water. However, open water areas and green spaces in cities are constantly decreasing, making water resources increasingly scarce. There is an urgent need for a method that aligns with the current urban status and can quickly assess the urban ecologicalenvironmental quality (UEEQ). Traditional UEEQ methods have abandoned the water factor, neglecting the influence of water on the ecological environment. In modern cities, water, which guarantees the operation and maintenance of the urban ecological environment, must be considered in the UEEQ system. Therefore, we propose a water benefit-based ecological index (WBEI). In the formulation of the WBEI, we integrate a water eco-factor, the thermal environment and the land cover type to represent the surface ecological environment. We first construct a surface potential water abundance index (SPWI) to describe the spatial distribution of water. The combination of the SPWI and the normalized difference latent heat index (NDLI) allows the WBEI to better evaluate the UEEQ around water areas. Then, we choose the land surface temperature (LST) to represent the thermal environment. To represent the land cover type, the ratio vegetation index (RVI) and the normalized difference soil index (NDSI) are adopted in the WBEI. Finally, we use an entropy-based fusion method to fuse these indicators and obtain the WBEI values. The performance of the WBEI is tested using eight datasets with a variety of environmental characteristics. The results show that 75% of the WBEI results are consistent with the EI values. The correlation coefficient between the WBEI and EI is 0.8883, which is significantly better than those of the other methods. The research shows that the UEEQ of the Qingdao West Coast Economic New Zone is declining continuously at a rate of 3.7% per year. From 2013 to 2017, the percentage of areas with good environments decreased by 21.46%, and the percentage of areas with poor environments increased by 12.76%. The UEEQ inside the city deteriorated radially outward along the main traffic route, the UEEQ in the suburbs did not change significantly, and the UEEQ in the water areas deteriorated significantly. These relevant research results can provide quantitative information for the green sustainable development of cities.

“…As a large number of people have been moved from rural areas to cities, the number and size of cities in China have greatly expanded. Although the rapid expansion of urbanization provides a driving force for the rapid development of China's economy, it has caused increasing pressures on resource conservation and environmental protection [1][2][3]. Up until now, there are two different paths towards China's urbanization.…”

Urban clusters are important carriers for cities to participate in international competition and cooperation, and a booster for urban sustainable development. This study measured the degree of urban clusters by utilizing the panel data of 278 cities in China during 2004–2016. Then, an extended meta-frontier data envelopment analysis (EM-DEA) model was applied to estimate the total-factor ecological performance (UTEP) and decompose it into two sub-index from the perspective of “resource conservation” and “environmental friendliness”. On these bases, we employed a dynamic panel data approach to examine and demonstrate the relationship between urban cluster and UTEP in two dimensions, and further explored transmission channels of urban clusters on UTEP by adding the mediating effect. The results show that resource conservation increases first and then decreases with the increasing of urban clustering level, while environmental friendliness showed the opposite trend, making the latter become the main way for urban clusters to improve the UTEP. Industrial structure supererogation and rationalization are transmission channels for environmental friendliness rather than resource conservation in the way of improvement of UTEP. Technology innovation, as well as technology diffusion, also improves UTEP to some extent. In addition, urban clusters in eastern and central China have the greatest improvement in UTEP, while such effects are not the case in western China. Urban clusters in the second half sample period are more conducive to the improvement of the UTEP, with these potentially being the gains from the improvement of the level and quality of urban clusters.
