Great attention has been paid to carbon bio-sequestration due to increasing concerns over global warming. Understanding the relationship between carbon bio-sequestration and its influencing factors is of great significance for formulating appropriate management measures for global warming...

The evaluation of ecosystem health in urban clusters will help establish effective management that promotes sustainable regional development. To standardize the application of emergy synthesis and set pair analysis (EM–SPA) in ecosystem health assessment, a procedure for using EM–SPA models...

The biogas-linked agriculture has experienced a rapid development in recent years in rural China, which serves both as part of the country's developmental strategies of cleaner energy and an important reaction to sustainable agriculture call. This paper provides an overview of the economic and...

The prominent conflict between consumption and environmental resources is acknowledged as a significant force in affecting the social-ecological community balance. The whole process of resource allocation, utilization, efficiency and outcome are crucial clues in uncovering the structural and...

An integrated evaluation of embodied energy, greenhouse gas (GHG) emission, and economic performance of a wind power generation system in China was conducted, using a range of indicators. Energy and GHG emission costs per unit profit are proposed as goal functions for potential low-carbon,...

Biogas plant construction has been boosted in rural China not only due to the immediate merit from biogas production but also the succeeding benefit from by-product utilization in agro-industry, both of which are significant strategies to address energy shortage and global warming issues....

To respond to the call of greenhouse gas emissions mitigation, an efficient carbon accounting framework should be proposed. Traditional narrowly defined estimation protocols that consider the direct emissions from native energy consumption may generally lead to underestimates of the carbon...

An absorption power/cooling combined cycle is proposed, and a thermodynamic analysis of the cycle is performed using log p-T, log p-h and T-s diagrams. Based upon two performance criteria, the overall thermal-efficiency and exergy efficiency, the cycle has been analyzed by means of a simulation....

The varying coefficient model is widely used as an extension of the linear regression model. Many procedures have been developed for the model estimation, and recently efficient variable selection procedures for the varying coefficient model have been proposed as well. However, those variable...

Passive solar house can improve indoor thermal comfort, but produce the problems of overheating in summer and inconvenient for operation. To solve the existing problems, solar wall with color changed was proposed and a full-scale experimental house with color changed was built in Dalian. Thermal...
