Abstract: This paper studies the Beijing Energy consumption and energy intensity of the present and future. First, the paper studies the energy situation in Beijing, including consumption, energy intensity and energy mix. Then through a combination of foreign experience and the status quo, we point out the general rules of energy growth and the various factors affecting the growth of energy consumption in Beijing. Next article is about the future of Beijing's total energy consumption for a short-term and long-term forecasts and Beijing's energy saving potential related analysis are also presented. Finally concluding remarks, the author points out the problems and findings which are conducive for Beijing to build green low-carbon city and construct a world city.

Abstract: The traditional technology of arsenic removal had been limited owing to their higher environmental requirements. But biological methods, especially microbial technology,had been the most promising technology because of its environment friendliness. This article analyzed and explored the mechanism and the latest research of microbial removal of arsenic. Based on the findings of the present situation, the research direction keys of this method were put forward.

Abstract: The relationship between microbial biomass and enzyme activities under heavy metal pollution had attracted much attention in ecology. The experimental sediment samples were supplemented with Pb and Cr and incubated at room temperature for a month. Microbial properties such as microbial biomass, urease, catalase and cellulase activities, together with several chemical properties such as pH, total organic carbon , oxidation-reduction potential, total nitrogen and phosphorus were measured to evaluate changes in sediment qualities. Our results demonstrate that heavy metals would inhibit sediment microbe biomass and enzyme activities. Such decreases in sediments microbial biomass and enzyme activities by Pb and Cr contamination may help to evaluate heavy metals contaminated soil ecologies.

Abstract: In this paper, we select the multi-dimensional evaluation index system based on principal component analysis for quantitative evaluation of circular economy in Chongqing . We use ARIMA model to predict Chongqing city cycle economic trends which rely on a comprehensive study in the development of circular economy status quote.

Abstract: Suitability of industrial land use in Nanfen District of Benxi City, a famous industrial-mining town in China, was evaluated in terms of niche fitness model. Results indicated the most suitable, sub suitable, barely suitable and unsuitable area for industrial land use in Nanfen was 91.23 km², 182.72 km², 182.08 km² and 162.97 km², respectively. Spatially, the most suitable and sub suitable areas were mainly distributed in urban area, and barely suitable areas were chiefly located in Xiamatang town, however, unsuitable areas were mostly scattered in Sishanling town. Industrial activity should be arranged in the most suitable area, so as to match actual resource niche and minimize environmental pollution and ecological damage.

Abstract: Chinese urbanization is developing rapidly; green building materials need an evaluation system to overcome the cost disadvantage that compared with the normal building materials. The life cycle cost (LCC) of the green building materials is the remarkable difference and also advantages in contrast to the normal building materials. An LCC evaluation system for green building materials has been set up by 4 modules; it is the first step to develop the evaluation software. To find an optimal design scheme, the entropy decision making method was used to support the decision maker to compare the different design schemes, and to calculate the best material selected scheme.

Abstract: In order to identify suitable land for crop planting, the suitability of cultivated land in Nanfen District of Benxi City, Liaoning Province was evaluated in terms of niche fitness model. Assessment index were selected from the viewpoint of natural, economic and social factors. Results indicated the most suitable area for cultivated land use in Nanfen was 124.23 km² and overpass the area of current cropland resource. However, current cultivated land-use located in the most suitable was only 16.61 km², which revealed layout for cultivated land was not reasonable in Nanfen. Cultivated land should be allocated in the most suitable areas by means of planning.

Abstract: Nowadays public participation is recognized as an integral procedure to achieving sustainable development as well as a good method of environmental governance. This study aimed to improve the quality of public participation in the field of environmental governance. To this end, it used Benin republic as a case study to provide an analytical review of two public participation approaches developed in Republic of Benin for environmental management. Results highlighted some keys limitation of each of those approaches. The study concludes with recommendations to improve the quality of public participation application in Benin.

Abstract: The accelerated process of urbanization and industrialization leads to the increase of sewage sludge production. The reuse of excess sludge which meets the idea of sustainable development is aimed to develop it into resources. Preparation of sludge-based adsorbents with various functions provides a new way for sludge utilization as a resource in China. The preparation method of sludge-based adsorbents and its application in wastewater and waste gas treatment are introduced. Suggestions about the research direction of sludge-based adsorbents in the future are point out.

Abstract: Nanfen is a mountainous town in East Liaoning of China, where plenty of industrial and mining enterprises were allocated. Suitability evaluation on residential land in Nanfen was of importance for local resident living. Evaluation results indicated the most suitable, sub suitable, barely suitable and unsuitable area for residential land was 208.08 km², 169.95 km², 149.51 km² and 91.46 km², respectively. Spatially, the most suitable areas were mainly distributed in Sishanling town, and sub suitable, barely suitable and unsuitable areas were chiefly located in Xiamatang town. Residential land in Nanfen should be unified and reallocated to better residents living environment.
