Economy in coastal cities plays an important role in China. It is urgent to protect environment with economy developing. Four types of sea water quality can be regarded as states of Markov Chain. Transfer probability is viewed as the function of sewage and investment in environmental protection. Based ...
In this paper we proposed a knowledge cloud service model to support sustainable development of marine economy. Through a brief explanation on why, what and how it illustrates the value and importance of knowledge services as a vital soft infrastructure for developing marine economy.
In order to meet the passengers increasing demands of travelling environment, to protect the environmental health along the rails and the railway staff and passengers' health, the trains have been gradually installed or modified closed waste collection toilet. With high concentrations of pollutants ...
In the next decade, China's demand for energy is still in rapid growth. Energy conservation and emission reduction requirement to our country with coal dominating energy production and consumption structure brings the severe challenge, to develop the low carbon, clean, efficient of the fossil energy ...
Stoichiometry in coagulation of biologically treated yeast wastewater using ferric chloride was investigated in this study. Experimental results show that there is a stoichiometric relationship between the optimal coagulant dosage and the concentration of organic compounds (expressed as CODcr) in the ...
Sustainable development is the critical theme of today's society. The enormous geothermal energy is supposed as renewable resource such as wind, solar and biomass. More significantly, because of its lower emissions of greenhouse gas (CO2), geothermal energy is effective on reducing the catastrophic ...
Based on FEPG, 2d water pond circulation induced by paddlewheels is simulated by finite element method. The principle of FEPG for CFD is analyzed. Circulations in the same pond induced by 3 different arrangements of the paddlewheels are simulated. Analysis result shows that: Numerical simulation Based ...

Chongqing is one of the carbonate rocks distribute most widely and the Karst develop strongest provinces, especially in Karst Mountain area, its rocky desertification area covers 8557.45km2, accounting for 92.45% of the city's. Therefore, as one of the key cities in Western Development, the cause and ...
With the rapid development of aquiculture, the pollution from aquiculture has become one of the important sources of countryside non-point source pollution in Poyang Lake watershed, and it also brings about serious problems of water environmental pollution. Based on the census data of aquiculture in ...
Biodiversity assessment constitutes a multivariate problem depending on several factors and consisting of various characteristics. In order to evaluate biodiversity and extract meaningful information about its trends, threats and dynamics, various biodiversity indicators or “bioindicators”, have been ...

The system is based on pig study, in order to facilitate the measurement of pig body weight, coupled with development of information technology. it uses a non-contact measurement means. Detection of pigs with body size and weight estimate system requirements, to B / S architecture based system software ...
This paper introduces the acquiring and feature of spatial data in marine fishery 3S integrated model. It analyses and compares the functions and features of several common GIS spatial data management models and discusses how to organize, store and manage the marine spatial data.
At present, water quality monitoring is the essential part to our country's aquaculture. In this paper, we developed a real-time water quality environment monitoring system based on wireless sensor network to acquire data of environmental factors of water quality. Also, the system can provide expert ...
The measurement and control of water salinity in aquaculture, environmental protection, and marine resource exploitation is crucial. This paper presents wireless method measure water salinity, it mainly analyses the theoretical of the measurements of water salinity, illustrates the effects of temperature ...
Based on analysis of the process and reasons for blue-green algae outbreak in Taihu Lake in 2007, from five areas, such as the quality of life for residents, the residents physical and mental health, employment, environmental awareness and government's public service, to defined the social impact of ...
Our country has already the relatively mature rural new energy applicable technology, but the use is still at the primary stage. This paper mainly analyzes the insufficient utilization of our country rural new energy applicable technology and its reason, and puts forward the using strategy of the rural ...
The feasibility of using constructed mangrove wetlands to treat saline municipal wastewater was evaluated in this study. Constructed wetland, acting as an ecological engineering alternative, is capable of reducing NH4+-N, TN, TP and COD from saline wastewater. During the 10 months' operating period, ...
Constructed wetland was used in this research for the treatment of saline aquaculture wastewater. Constructed wetland could removal organic matter and nutrient effectively. The planted unit showed better capability of COD, TN and TP removal than unplanted unit obviously. Treatment performance of planted ...
