With the development of economic globalization, corporate social responsibility has become a research focus. Firstly, based on Carroll's social responsibility theory, the scope of corporate social responsibility, including economic responsibility, legal responsibility, ethical responsibility and philanthropic responsibility (or self-responsibility), was defined. It is shown that corporate social responsibility...
The microorganism (strain F10) with 63.2% denitrifying intensity was isolated from river sediment. By checking the individual morphology, colony culture characteristics, DNA sequencing and 16S rDNA gene bank, F10 was identified as Alcaligenes faecalis. The strain is expected to be of a source organism for in situ bioremediation or bioaugmentation.
When we recognized that knowledge spillovers remain ambiguous, it helps the researcher to avoid studying the specific mechanisms through which the two phenomena about ‘geography’ and ‘innovation’ are linked. Knowledge spillover is the observation that innovative activities are strongly concentrated at the geographical level and that firms located in certain areas are systematically more productive...
Based on the water quality investigation data from August in 2009 to July in 2010, the water environment quality of Zhanjiang Mangrove Nature Reserve was assessed using single water quality parameter model, integrated water quality index model, organic pollution index model and eutrophication assessment model. The results showed that the key pollutants were dissolved inorganic nitrogen (DIN), dissolved...
Five two-chamber microbial fuel cells with five different substrates as fuel were constructed. And the anode chambers of MFC were inoculated with the same seed sludge. All the MFC can generate continuous electricity. The Simpler substrate is, the higher electricity MFC will obtain. The MFC with sodium acetate or glucose as fuel obtained higher power output comparing MFC using other substrates. The...
Total bacterial count, carbon substrate utilization and diversity of microorganism is analysed. The results show that there are many differences between two different watershed ecosystem in Wen Yu River.
Terrestrial distribution with soil bacteria, fungi and actinomycetes amount of the Xilin River natural wetland was investigated. The result that soil microbial community compositions of typical grasslands and natural wetlands, with the elevation changes gradually reduce the soil moisture content from bed sludge (HX) to typical steppe (DT), changed significantly. The total microbial and aerobic bacteria...
The post-disaster reconstruction should be combined with Human inhabitation and settlement environment construction, which can achieve sustainable development strategy, promote economic growth, make the social development be harmonious with the environmental protection. The post-disaster reconstruction of Longan town, Pingwu County in Sichuan province has combined supporting systems of infrastructure,...
Urban agriculture is an integrative concept which encompasses economy, society, ecology, landscape, education, demonstration, et cetera. However, the research on the application of urban agriculture to ecological residential district planning is still rare now. This essay first describes the origin, development, characteristics and multi-function of urban agriculture, then presents the significance...
The vegetation map, with a complex landform of DAHUABEI region in Wula mountain was produced based on the field vegetation investigation, and image interpretation, using the ALOS data and a Digital Elevation Model (DEM). The spatial distribution of the main vegetation types and their relations with topographical factors were statistically analyzed under the support of GIS, combining the vegetation...
Construction of rural concentrated residential is an important part of the new rural construction and whether it can proceed smoothly or not depends on two faces: “executive power” and “planning power” from top to down, Spontaneous “market forces” of the farmers from bottom to up. In this article, from the view of the latter, we invested the main factors which affect the relocation will of farmers,...
In this paper, the competitiveness of various cities of Shaanxi province is analyzed. Firstly, the article establishes the index systems of city competitiveness; furthermore, the comprehensive scores on competitiveness of all the cities in Shaanxi province are calculated by means of the Principal-Components-Analysis method. Secondly, the locations of breakpoint of the adjoining cities are measured...
The vegetation succession and soil enzyme activities restoration with different growing years was analyzed by applying the spatio-temporal substitution method. The result showed that H. Rhamnoides and A. Desertoru are predominant species of the shrub layer. With the restore years prolonging, the species diversity index (H′, 1/D), saccharase, urease, phosphatase and catalase activities were increased,...
Atrazine removal in membrane bioreactor (MBR) and conventional activated sludge reactor (CAS) bioaugmented by genetically engineered microorganism (GEM) was investigated. PCR-DGGE was used to analyze microbial community variation of both bioreactors in different running stages. The results indicated that high removal efficiency of atrazine was obtained in both bioreactors bioaugmented by GEM. The...
The nature reserve is an important and special carrier of the ecotourism in China. Tourism on nature reserve not only need to pursue an economic performance, but also need to obey the initial target of protection, pursuing coordination among the functions of protection, research and educating etc. There are a series of problems in the nature reserve tour ism industry currently, such as the problems...
Urban spatial pattern (U-S-P) is an important embodiment of general characteristics of the urban space layout and relations between component elements. But there are few research into the spatial relations within U-S-P. The paper generalizes the elements system for the expression of U-S-P, builds the the corresponding relation with the entities in GIS spatial relationships theory. RCC-8 model and...
Zooplankton spatial distributions and additional environmental features of Tianwan Offshore Area were studied in August 2009 at 14 stations. The abundance, distribution, and diversity of zooplankton were analyzed. copepods, larval stages, and hydromedusae dominated the zooplankton community. At total 72 species of zooplankton with 13 groups were identified. With 20 Zooplankton larvae, 19 Jellyfish,...
The community of wasteland, secondly shrub, Pinus yunnanensis forest, Alnus nepalensis forest, mature Pinus armandii forest, half-Mature Pinus armandii forest and mixed forest were selected to analyze the carbon-sink function by establishing recursive trees regression biomass model with different components contain the biomass of forest, stick defoliation reserves and soil carbon. It is indicated...
This paper made an example as High-tech Industrial Zone in Jianhu, for researching the contradiction between ensuring economic growth and protect the natural environment that have been faced by planning about sustainable development of country economic development zone with industrial transferring, and preliminary discussion the way in planning for natural environment protection and make that develop...
Nitrous emission in SBR denitrification process and the microbial community impact on it were studied. Result showed that the relationship between the N2O emission and conversion efficiency of nitrogen in system during the wastewater nitrogen removal process is negatively correlated. Under the experimental conditions, with NH4+ concentration increased, the efficiency of nitrogen transformation is...
