By the analysis of logistics development promoting the division of labor, this paper calculated the similar coefficient of 28 manufacturing industries by the panel data of 1990–2008 in the Yangtze River Delta of China. The division of labour standards was as the explained variable, and the logistics development level including the per capita output and network density were as the explanatory variables,...
The application problem of unascertained system theory in water resources sustainable development and utilization evaluation has been explored having certain novelty and creatively according to the characteristics of containing unascertained information in sustainable development and utilization estimation study of water resources in Chaohe river basin. At the same time, the classification of water...
Chengdu-Chongqing area, as a new economic growth location in China, it is more urgent to need the interactive development for higher education with the rapid economic integrational development. This paper overviews the joint development of higher education at home and abroad, and gives a comprehensive analysis on feasibility for the linkage of higher education in Chengdu-Chongqing area. At last, this...
A method of underwater topographic survey based on ground penetrating radar (GPR) with global positioning system (GPS) was proposed. It obtained plane coordinates from GPS and elevation acquisition from GPR. The method was proposed to detect riverbed topography in the Yellow River. The radar antenna was used directly in vessel to collect underwater topography, process and analysis on obtained GPR...
As to the urban Voronoi diagram based on the plane measurement, any point may freely passes in and out of the horizontal and vertical transport network, but the situation of direct transport without obstacle is relatively rare in the objective world, most of the transport networks are separated by the obstacles in various shapes, the linear obstacle is the most important one among the obstacles in...
Based on the consideration of related literature and China's reality, this paper combed the domestic and international research on the economic behavior of peasant households and analyzed special economic behavior of peasant households in China, then analyzed the causes, effects, impact factors, countermeasures of China's from a macro perspective. In the end, from the perspective of peasant households...
Dongping County of Tai'an City has a long history and rich ancient cultural relics. With a unique natural scenery and traditional cultural superiority, it has the most distinctive and the most valuable tourism resource-the Shuihu city. But there are many problems in cultural tourism development, such as the exploring insufficient of tourism culture deposits, the failure of synchronous follow-up of...
Visualization of the meaning and main content have been introduced. The author analyzed three-dimensional visualization framework structure of water allocation decision support system and main using technology, the functional design, the visualization environmental construction and the human-computer interaction technology et al
China's natural environment and resources are distributed in unbalance. In order to keep the sustainable use of environmental resources and realize the coordinated development of economy, society and environment, China sets some important parts about environmental protection in the Constitution, and a lot of local environmental regulations are made according to the need of local environmental protection...
The concept of water bank is introduced from the different perspective of international and domestic. Water bank has been demonstrated that it is a effective means of regulating water surplus and deficiency, saving water transaction costs and advancing water resources sustainable utilization as a agency of water right tenancy and water quantity both vendor & purchaser taking Chaohe river basin...
Riparian buffer strip plays an important role in preventing agricultural non-point pollution and protecting river quality. Purification effect of nitrogen and phosphorus in Nongjiang river was studied by selection of a typical sampling transect, five sampling sites were selected along the sampling transect. Every two neighbouring sampling sites formed a buffer substrip and four buffer substrips were...
China's property rights market has gradually developed as an indispensable part of Chinese capital market. This paper takes the Changjiang River Property Rights Market as an example to study the integration of our country's regional property rights market. With the fundamental theories of property rights exchange as a basis, this paper explore and discuss the possibility of building a common market...
As one special style clusters, commercial enterprises clusters exist broadly but are paid less attention. This paper analyses the character and the agglomerations principle of commercial enterprises clusters, and researches into its competitive advantage under Cournot competition and resources integrating of commercial agglomerations.
Presently automatic texture mapping is a hot topic in computer graphics filed. Most previous automatic texture mapping algorithms have suffered from been too slow or could only use a limit set of feature points of the model. We introduce in this paper a new constrained-based method for automatic texture mapping that deal with these problems for planar meshes. Our critical improvements include generalizing...
City management is an important object of historical geography research. The market town is the important part of the city. Town system as the primary framework of the urban system has its own development process. The development of market town makes the urban system more perfecting and complex. In the course of urbanization, the town plays an important role, which is the core and hub of rural urbanization...
As the requirement of rural tourism from urban residents increases, the Rural Home Inn tourism develops rapidly with its unique spatial structure. Based on the analysis of the current development and the spatial layout rules of rural tourism, this paper proposes the urban-rural spatial structure of rural home inn and six models of its space format. By analyzing the case of the tourism development...
In this paper, the 2 dimensional numerical model is established to simulate the hydrodynamic and the erosion/deposition environment for present status at east coast of Yantai, nearby Yangmadao Island. The tide verification and the current verification prove that the simulation results conform to the observation data. Based on the simulation results, the authors then simulate the hydrodynamic and the...
Land use/cover change in the coastal zone is a new research hotspot. Based on land use maps obtained from Landsat images (1979, 1989, 1999 and 2008), this paper detected the spatial orientation of land use changes in the coastal zone of Bohai Bay with a integrated geographical approach of land type barycenter movement, buffer analysis, land use degree and Shannon-weaver Index. Results showed the barycenters...
This paper presents the short-term joint optimal simulation operation simulation method for Qing River cascade hydropower system, which considering on time-of-use (TOU) power price and pursing maximum power generation benefit. In this method, the temporal-spatial variation of flow between cascade hydropower stations is considered. Correlation analysis is used for calibrating the measured data between...
The paper analyzed water consumption and the yield of winter wheat in Liuyuankou irrigation district, and built water production function of the winter wheat. The studied the calculating method of water consumption under peak yield and the lowest water requirement coefficient respectively. According to the above method, the paper selected four typical irrigation districts in lower Yellow River to...
