This paper calculates the ecological footprint, ecological capacity and ecological pressure index of Shaanxi Province from 1991 to 2011 by the method of ecological footprint. And it gets the ecological security level trend in 21 years of Shaanxi Province. Then the paper selects five different indicators to establish index system. The state index of social development in Shaanxi Province is calculated...
Environmental Resource Legislation is an open complex giant system. After studying and improving the famous comprehensive integration theory provided by Tsien Hsue-shen. We design an environmental resource legislative decision support system based on the method of comprehensive integration.
Climate change has become a major international environmental problems, which has threatened to human survival and development. One of the fundamental measures to take actions to climate change is to control the anthropogenic emissions of greenhouse gases. Taking actions to climate change involves political, economic, technical, legal and many other fields, and law is a code of conduct, which is formulated...
Rapid economic development is the main driving factor for carbon emissions. In order to explain the relationship of economic development and carbon emissions, this paper cited the carbon emissions decomposition analysis model to estimate annual carbon emissions in China from 1978 to 2009, and analyzed the trends and characteristics of carbon emissions. On this basis, this paper adopted grey relational...
The external benefits of renewable energy were systematic analyzed and described in detail, such as the energy benefits, the environmental benefits, the health benefits and the macro-economic benefits. The monetary calculation methods of environmental and health benefits were discussed in-depth, which can offer help to planners and policy makers to understand the potential benefits of renewable energy,...
After several years of implementation, the EIA system in China has developed into a framework that is suitable for its unique conditions. However, since there are some problems in China's EIA system, the aims of this paper are to evaluate both the strength and weakness of practice and provide suggestions for its improvement.
Collaborative tagging systems (CTS) enable Internet users to annotate for resources using custom tags, and the tags reflect the user interest and thus form a user profile. However, the flexibility of tagging brings large number of synonymous and polysemous tags which make the use of these profile information to personalize resource recommendation difficult. We propose to use graph-based clustering...
TSP (Traveling Salesman Problem) is a kind of typical NP problems, mostly settled by genetic algorithm (GA). Differential Evolution Algorithm (DE) is a kind of new Evolution Algorithm which has many similarities with GA. We proposed to solve TSP problem by improved differential evolution algorithm. Added an auxiliary operator for regulating integer sequence to mutation process, and replaced the original...
With the grey correlation methods of the grey system theory , the paper study on the coordination degree quantitative models of economy-environment-society structure on BinXian. According to the variation of each index, the weight coefficients in the model are derived from the avail value of data reflected by the information entropy, the subjective influence of weight allocation can be avoided effectively...
Based on the current environmental situation in Shaanxi Province and the conception of Environmental Carrying Capacity (ECC) , an evaluation index system of ECC in Shaanxi Province was established, including environmental pollutant-accommodating capacity (EPC), resource supply capacity (RSC) and man-made support capacity (MSC). In the meanwhile, the ECC in Shaanxi Province from 2001 to 2006 was evaluated...
In this paper, we proposed a novel system integration approach to combine bi-static UWB radar and two cameras to realize the recognition of human motions. In this recognition system, cameras are used to localize peoplepsilas regions while radar is used to obtain their 3D motion models, which can be matched in our 3D motion library in order to recognize their motions. To confirm the effectiveness of...
This paper sets up a dynamic model of energy consumption structure in China and selects two different groups of data to simulate and forecast the trend of the energy consumption structure. The forecast result is that the consumption rate of coal will decrease, while the rates of electricity, natural gas and petroleum will increase. Because the two groups of data are from different periods, there is...
In order to represent 3D GIS spatial entity effectively, a hybrid data structure model called BOT model (block octree tetrahedron model) is presented on the basis of geological block model, which combines octree and tetrahedral network (TEN) structures. With BOT generation algorithm, the block model is redivided with octree as general shape description and TEN as partial precise description, in which...
