Development and environmental protection constitute an organic whole. In China, it is in the stage of rapid development of society, China is faced with many environmental problems, improving the level of the ecological environment monitoring and management is particularly important. Because of the technical limitations of the traditional environmental monitoring and management, it can not adapt to...
In China, researches on classification of fundamental types of geomorphologic form emphasize the integrity of geomorphic units and regional landscape units, and such research results have been mostly applied for some large-scale areas according to a large elevation variation normally. However, there is lack of an automatically effective method within these researches, which can be used to delineate...
To solve the problems in environmental monitoring arising from remote data acquisition, real-time transmission and analysis, this paper researched the principle of wireless communications SMS / GPRS and the technology of seamless integration with GIS. The system architecture was designed and key technical solutions were implemented. Based on the SMS / GPRS technology, the wireless real-time transmission...
This study focuses on teaching students about resource recycling and classification through an instructional website based on WebQuest. The purpose of this study is to demonstrate the impact of different teaching strategies on the learning performance of environmental education through quantitative methods. The participants in this study were separated into three groups: traditional instruction, traditional...
The water quality computer simulation is an important method to study the water flow field and the change of water quality in lake. In this paper, combining two-dimensional shallow water dynamics-water quality model with FLUENT software to simulate the water quality of Daming Lake in Jinan. The results can reflect effectively the changes of water flow and water quality of Daming Lake in actual situation,...
This paper reviewed the international and China' s pilot program progress of VEAs, analyzed experiences, driving forces and barriers in the process of advancing VEAs in the past six years in China. The results showed: VEAs have become one of the most efficient policy tools in environmental management in most of the OECD member states. However, in China, which are still at an initial stage though developed...
Tanzania is undergoing an unprecedented boom of IT industries. But awareness of environmental issues connected with ICT is almost nonexistent in Tanzania. ICT development without an eye on environmental protection is not sustainable. As of 2009 Tumaini University's B.Sc. program in IT has included a Green Computing course as an obligatory part of IT studies. That course aims at raising students' awareness...
Planning for economic development and environment protection in Erhai Lake basin to balance economic and ecological benefits is urgent. Inexact multi-objective programming (IMOP) could help us to optimize the planning. The paper presents particular model for solving the problem. With the necessary data collected, the research team will go on to use LINGO software and the formulated models in this...
This paper puts forward the application of Matlab image processing technology in sewage monitoring system. The percentage of the bubbles on the surface of the water can be got by using some functions in the image processing toolbox of MATLAB, such as binaryzation, dilating, erosion and so on. The automatic alarm will be raised when the percentage of the bubbles exceeds the setting value. Sewage emission...
As the environmental problem is emphasized by the whole society increasingly, the needs and demands of the environmental data sharing and service are becoming more and more urgent. In the course of constructing State Environmental Data Center (SEDC): organizing, standardizing and strengthening exchanges of data and information between sections; setting up environmental foundation database of the national...
Using particle swarm optimization (PSO) to optimize BP neural network model is proposed in this paper. The new model is more quickly and accurate. The basic idea of this model is: Firstly PSO is used to optimize the BP neural network's initialized weights, an optimized result is got; then based on the optimized result the BP neural network is used for further optimization. We can use this model for...
The formal publication of the latest brand new generation Microsoft .NET 3.5 framework indicates that this software giant is successful evolving on its plan. This paper introduces the technology based on .NET 3.5 framework and its new features, advocates service oriented architecture to construct and design network application program fast, then provides a system design of a green community Live Green...
Based on the data that obtained from Liaoning Province environmental quality statistics and LANDSAT 5 satellite image resolution data, eco-environmental quality of Liaoning coastal highway area was respectively assessed with expert assessment method and support vector machine model. Firstly, five assessment indexes of eco-environmental quality were defined which are organism abundance index,vegetation...
The vehicle exhaust gas emission is directly related with the quality of air. This paper describes the research and development of an event driven RFID based exhaust gas detection system applying the service oriented architecture for the purpose of environmental protection. An edge engine supporting the EPCglobal ALE specification, a complex event processing engine dealing with the complex streaming...
The pollution of Qinhuangdao Port is the bottleneck of economic development, so how to correct the environmental assessment of the work environment has important significance. The main pollutants in Qinhuangdao port is coal dust pollution, through various observation points on the measurement indicators of pollutants by EPA experts scoring can get a group of data, and then through various BP neural...
A fuzzy BP neural network model based on particle swarm optimization (PSO) is proposed in this paper. The basic idea of this model is, firstly, the relative membership degrees of fuzzy mathematics are used for deal with the input sample, and then use the algorithm optimizing. Secondly, PSO is used to optimize the BP neural network's initialized weights, an optimized result is got. Then based on the...
The main purpose of the paper is to present the www hydrocarbon pollution monitoring system which is under development at the Warsaw University of Technology (WUT). The dedicated system server collects data from mobile GSM/GPRS accessed observation points, and delivers information on potential pollution to the authorized www clients. The emergency alarm information is planned to be send directly to...
From the viewpoint of environmental protection, the recycling of wastes becomes ever more important. In such a field, there is the manner of recycling or reuse, we need to develop a simple technique on advertising to promote recycling and reuse based on the local autonomy. Especially, the field of sorting for reuse requires a simple sensor system that identifies the materials, shape and size of an...
