Based on the cause of sediment transporting equilibrium degree theory and the 20 years date of water and sediment of the Yellow River downstream, the equation of water and sediment item relational sediment transport equilibrium degree of six sections of the Yellow River downstream were established. Used the fuzzy cluster analysis theory, the method of forecast and control of river pattern of the Yellow...
Based on field investigation and indoor analysis, distribution characteristics of four available trace elements, including Cu, Fe, Mn, Zn, in the terrace land in loess region, was studied. Results indicated that, these four available trace elements distributed unevenly across soil profile, and its variation coefficient was high, which reached medium and high level. Distribution trends of these four...
A method is proposed to assign the priority for indicators in this paper. This proposed method combines the group analytic hierarchy process (group AHP) and cluster analysis, therefore, it highlights the democracy and avoids the extreme individual preference in group decision. This method has been used to weight 17 identified indicators for assessing the energy efficiency of residential building in...
With the aid of the spatial analyzing technology, three periods land use data of the Longchuanjiang catchments have been obtained. Raster-conversion and cartographic algebraic operation were conducted of the land coverage data, using a complex method integrating GIS spatial analysis with traditional statistical analysis, to create a new GRID database. Based on the database, the effect of land use...
From the perspective of value chain of commercial vehicle industry, this paper constructs a multilayer index system of competitiveness evaluation of the commercial vehicle industry. This system is composed of environmental competitiveness, innovation competitiveness, manufacturing competitiveness, spare parts competitiveness and market competitiveness, and its subsystems. On the combination of Delphi,...
China is one of the countries with most serious occupational injuries in the world, but the search and use of relevant data on occupational injuries is very backward. A more comprehensive database of occupational injuries, which can conduct statistics, classification, comparison, analysis, forecasting on the occupational injury according to different industries and categories more comprehensively,...
Based on 1961-2008 day-by-day meteorological data observed by Linyi stations, using correlation analysis and wavelet analysis method, the correlation and tendency of the pan evaporation and the main influence factors (sunshine, temperature, daily temperature range, relative humidity and wind speed, etc.) of the recent 48 years are researched. The results show that, in recent 48 years, the average...
Combining extension engineering method with cluster analysis, the classic and limited matter elements were constructed according to air quality standards and main air affecting factors. The logical domain was extended from (0, 1)to (-∞ ,+∞), meanwhile, the quantitative analysis in the classic matter-set which only judged by Yes or No was extended to qualitative analysis, which could show the administrative...
In this study, Landsat TM and ETM+ images in 2000 and 2008 were selected to to explore the relationship between land surface temperature and land use pattern in Guangzhou, and to investigate the impact of land use changes on the urban heat island effect. First, the mono-window algorithm was utilized to retrieve land surface temperature from thermal band of Landsat TM/ETM+ image. The mean-standard...
This paper examines whether the level of debt financing affects the equity agency costs between shareholders and management and the one between controlling shareholders and minority shareholders. We use empirical research method to analyze a panel data sample of A share listed companies in Shanghai and Shenzhen Stock Exchange from year 2007 to 2009 and finds that companies with proper financing structure...
The urban bus traffic network is one of the important instance in complex network researches. The robustness of public traffic networks is not only related to the efficiency and capacity of people movement, but also the critical aspects in future urban regulation and design. Traditionally, researches pay more attention to the influence of high-degree vertices (degree of a vertex is the number of other...
The relationship between entrepreneurial capability and enterprise growth is analyzed in the paper. Although the impact of learning capability and innovation capability of entrepreneur on the enterprise growth is emphasized in the existing researches, but this paper analyze the topic in the context of China, and the result shows that strategic capability, management capability and relationship capability...
In this study, According to logic of business diversification and firm performance, assuming exists an optimal degree of diversification enterprises under certain conditions, according to empirical analysis of 109 listed companies, we get two conclusions: First, the higher level of diversification of listed companies, its Price-earnings Ratio is lower, that is to say it is harder to get approval by...
The aim of this study is to examine the influence of environmental satisfaction, job satisfaction, and Big Five personality traits on subjective well-being. Data were collected from white-collar workers across four Chinese cities in 2009. All the research variables were measured with multi-item instruments with good psychometric properties. The research found that environmental satisfaction, job satisfaction,...
In this paper we apply a Data Envelopment Analysis (DEA) for measuring changes in total carbon emission efficiency between 1986 and 2008 across Chinese regions and then estimate driving forces of regional carbon emission performance (MCPI). A long-run relationship has been detected and the coefficients, estimated using Kao's method, are statistically significant mostly. Our results indicate the positive...
According to statistical analysis, the first half of 2009 once China surpassed the United States became the world's first automobile-producing country, while China's auto consumption, the proportion of total world consumption has reached 12%. In the trend of development of modern logistics, automobile enterprises must be based on the survival of the entire supply chain's competitive edge relies on...
Regional Logistics and regional economy have a significant correlation. From the perspective of the logistics industry agglomeration, using the logistics industry data of 31 provinces in China, selecting three main indicators impact on the regional logistics industry based on previous research, entropy method and cluster analysis, combining to have a empirical study on overall development and characteristics...
In this paper, we based on the Tibet, Qinghai, Sichuan, Gansu, and Northwest Yunnan of China five regions' primary school Tibetan vocabulary as the main research object, by using statistical measurement method to analysis single word repetition, single volumes and volumes of lexical reiteration. The results showed that: (1) Teaching vocabulary is basically consistent with complex memory rules. (2)...
With regional economy development, regions interact each other and aren't independent any more. This paper aimed to reveal how the regions (provinces) effect to each other in terms of industry from spatial angle, put forwards and defined four modes of inter-regional industrial interactions based on basic regional agglomeration and radiation theory, and explored quantitative measurements combining...
This paper presents the empirical analysis and research on the regional difference of urban residents' consumption structure in china based on generalized main composition and clustering analysis. First introduces 8 resident's urban consumptive indices from 31 provinces and cities to the log ratio analysis which is one of the generalized main compositions in order to bring out a comprehensive index...
