This scarcity is leading some countries and areas to face difficulty in accessing drinking water. As the UN recently stated “by 2050 water shortages and harder access will be reached by around 2/3<sup>rd</sup> of the world total population” [1], thus, there is a high need to treat and reuse wastewater for domestic purposes, which will lead to less reliance on fresh water as an initial water source. Greywater—defined as the water produced in domestic houses including sinks and bathroom showers, and excluding any blackwater mix which is collected from toilets—is a type of wastewater. Greywater accounts for up to 75% of the daily water produced [2] while it has fewer contaminants when compared to blackwater. This makes greywater a focal point for treatment, and reusing to conserve fresh water and approach net zero water concept. Even though the definition of greywater is the same globally, its criteria can differ from one country to another, from one building to another, or even from the same person’s usage along the day. Accordingly, several treatment methods evolved over years aiming at treating the produced greywater for reuse mainly in irrigation and toilet flushing. The objective of this paper is to demonstrate a novel net zero wastewater approach applying cradle-to-cradle concept for urban communities;while also proposing a sustainable greywater treatment technique that is environmentally friendly, cost-effective and socially acceptable.展开更多

At present,the development of non-profit organizations in urban communities is still faced with many problems,such as difficulty in raising funds,lack of incentives that results in low enthusiasm for volunteering and low participation of community residents,etc. It is urgent and practical significance to study,analyze and solve the problems faced by non-profit organizations in urban communities. That article focuses on the analysis and discussion of the problems facing the development of non-profit organizations in urban communities,and proposes countermeasures to solve the problems.展开更多

Urban areas,which are characterised by massive construction that reduce local vegetation coverage, are subject to the absorption of a large amount of solar radiation,which is only partially released into the atmosphere by radiation in the thermal infrared.展开更多

The personal security is to protect the resident's life and physical health, public safety means that the residents don't suffer from physical damages or property damages in daily life, and humanistic ecological security is interpreted as that ideas of harmony, fairness, balance implied in ecology are used to coordinate the social relations of settlements, alleviate the increasingly serious social problems of residential space differentiation. In light of serious community ecological safety issues in China, the corresponding measures are pointed out: road system of "separating people and vehicles"; consideration of disaster prevention and mitigation in residential space design; the community construction from culture, environment, management and service; response to the residential space differentiation.展开更多

In particular, road linkages represent key characteristics of spatial dependence and distance decay, and are of great significance in depicting spatial relationships at the regional scale. Therefore, based on highway passenger flow data between prefecture-level administrative units, this paper attempted to identify the functional structures and regional impacts of city networks in China, and to further explore the spatial organization patterns of the existing functional regions, aiming to deepen our understanding of city network structures and to provide new cognitive perspectives for ongoing research. The research results lead to four key conclusions. First, city networks that are based on highway flows exhibit strong spatial dependence and hierarchical characteristics, to a large extent spatially coupled with the distributions of major megaregions in China. These phenomena are a reflection of spatial relationships at regional scales as well as core-periphery structure. Second, 19 communities that belong to an important type of spatial configuration are identified through community detection algorithm, and we suggest they are correspondingly urban economic regions within urban China. Their spatial metaphors include the administrative region economy, spatial spillover effects of megaregions, and core-periphery structure. Third, each community possesses a specific city network system and exhibits strong spatial dependence and various spatial organization patterns. Regional patterns have emerged as the result of multi-level, dynamic, and networked characteristics. Fourth, adopting a morphology-based perspective, the regional city network systems can be basically divided into monocentric, dual-nuclei, polycentric, and low-level equilibration spatial structures, while most are developing monocentrically.展开更多
