It is indicated that the long-term mean sea level variation affects notably tidal waves in this region. Generally, the tidal amplitude increases when the mean sea level rises, but this relationship may be inverse for some sea areas. The maximal variation of tidal amplitude takes place in the zones near the Fujian coast and the Zhejiang coast, rather than the shallowest Bohai Sea. The maximum increase of M2 amplitude can exceed about 15 cm corresponding to the 60 cm rise of the mean sea level along the Fujian coast. The other regions with large variations of tidal amplitude are those along the Jiangsu coast, the south-east coast of Shandong, and the south-east coast of Dalian. The propagation of tidal waves is also related to mean sea level variation, and the tidal phase-lag decreases generally when the mean sea level rises. Almost all the regions where the tidal phase-lag increases with rising mean sea level are close to amphidromic points, meanwhile the spatial area of such regions is very small. Because the influence of mean sea level variation upon tidal waves is spatially marked, such spatial effect should be considered in calculation of the tidal characteristic value and engineering water level. In the region where the amplitudes of the major tidal constituents increase, the probable maximum high water level becomes higher, the probable maximum low water level becomes lower, and both design water level andcheck water level increase obviously. For example, the design water level at Xiamen increases by 13.5 cm due to the variation of tidal waves when the mean sea level rises 60 cm, the total increase of design water level being 73.5 cm.展开更多

Only when the value of farmland is fully appreciated in commercial markets can farmland preservation be effectively achieved. The current study constructed a model to evaluate the economic, social, and ecological value of farmland in China according to the connotation of values. As a case study, the value of Chinese farmland was estimated in 1999, 2002, 2005, 2008, and 2011 using the established model. Although the amount of farmland was greatly reduced from 1999 to 2011 due to constructive occupation, agricultural restructuring, ecological restoration, and disaster destruction, the value of this farmland increased from 220.71×1012 to 736.26×1012 RMB Yuan as a result of the multifunctional nature and scarcity of farmland during the same period. The potential value of farmland in China was huge, but the value in the market was greatly underestimated, especially in regard to its social and ecological value. This study proposes a new method that integrates the discounted value of all future services provided by a natural resource(for the society and individuals) to evaluate the resource assets, provides a scientific foundation for the preservation and operation of farmland assets, and explores ways to increase farmers' property income.展开更多

Then,area change and annual changing rate of land use type in Guangdong Province are calculated by the analysis method of land use change. Based on this,ecosystem service value assessment method is used to discuss the variation of ecosystem service value in Guangdong Province. Result shows that ecosystem service value of land use shows a decreasing trend in Guangdong Province,having reduced from from 635 036 billion yuan in the year 1996 to 632 394 billion yuan in the year 2008. Ecosystem service value has reduced by 2 642 billion yuan,a reduction rate of only 0.416 1%. Farmland,woodland,grassland,wetland,land for water conservancy facilities,and unused land have all reduced. But garden plot,traffic and transmission land,water area,and residential point and other construction site have increased. The major characteristics of land use change the years 1996-2008 in Guangdong Province are the internal adjustment of agricultural structure and the increase of construction land. Land use change and adjustment direction are basically rational and the ecological environment is stable.展开更多

An exploratory qualitative design is used. The results are based on interviews with professionals and students practicing Chinese medicine (TCM) and lay people from three urban sites. Minor psychological problems have traditionally not been labelled as disorders or illnesses but challenges in daily living or as “heart problems” and seemed to have less serious consequences than we are accustomed to think from a modern western outlook. “Problems of life” rather than sickness was the category that best summarized perceptions of such problems among the Chinese. It points to a salutogenetic perspective reflecting perception of mental health and MPP as processes of adaption and interpretation of meaning rather than medical conditions or sickness. Due to the influence from the West these problems are, however, more often comprehended as a health problems or even sickness, and not solely natural problems of life.展开更多

Synthetic tests show that the improved Bayesian approach has a superior performance compared to the Bayesian approach as well as the widely used maximum likelihood estimation (MLE) method in fitting the real variation of b-values. We then apply the improved Bayesian approach to North China and find that the b-value has a clear relevance to seismicity. Temporal changes of b-values are also investigated in two specific areas of North China. We interpret sharp decreases in the b-values as useful messages in earthquake hazard analysis.展开更多

Only when the value of farmland is fully appreciated in commercial markets can farmland preservation be effectively achieved. The current study constructed a model to evaluate the economic, social, and ecological value of farmland in China according to the connotation of values. As a case study, the value of Chinese farmland was estimated in 1999, 2002, 2005, 2008, and 2011 using the established model. Although the amount of farmland was greatly reduced from 1999 to 2011 due to constructive occupation, agricultural restructuring, ecological restoration, and disaster destruction, the value of this farmland increased from 220.71×1012 to 736.26×1012 RMB Yuan as a result of the multifunctional nature and scarcity of farmland during the same period. The potential value of farmland in China was huge, but the value in the market was greatly underestimated, especially in regard to its social and ecological value. This study proposes a new method that integrates the discounted value of all future services provided by a natural resource(for the society and individuals) to evaluate the resource assets, provides a scientific foundation for the preservation and operation of farmland assets, and explores ways to increase farmers' property income.
文摘Based on the previous research and the 1996 and 2008 land use change survey,land use type of Guangdong Province is divided into 10 types of farmland,garden plot,woodland,grassland,residential points and other construction sites,traffic and transmission land,land for water conservancy facilities,wetland,water area,and land hard to be utilized. Then,area change and annual changing rate of land use type in Guangdong Province are calculated by the analysis method of land use change. Based on this,ecosystem service value assessment method is used to discuss the variation of ecosystem service value in Guangdong Province. Result shows that ecosystem service value of land use shows a decreasing trend in Guangdong Province,having reduced from from 635 036 billion yuan in the year 1996 to 632 394 billion yuan in the year 2008. Ecosystem service value has reduced by 2 642 billion yuan,a reduction rate of only 0.416 1%. Farmland,woodland,grassland,wetland,land for water conservancy facilities,and unused land have all reduced. But garden plot,traffic and transmission land,water area,and residential point and other construction site have increased. The major characteristics of land use change the years 1996-2008 in Guangdong Province are the internal adjustment of agricultural structure and the increase of construction land. Land use change and adjustment direction are basically rational and the ecological environment is stable.

文摘Conducting rural social investigation is the excellent tradition of the Communist Party of China.Since the reform and opening up,the Communist Party of China has undertaken several times of rural investigation,fully grasped the first-hand data of rural development situation of China,and formulated scientific policies and measures.These promote tremendous changes in rural development.Rural investigation of the Communist Party of China covers a wide range of topics,including politics,economy,education,science and technology,health care,sanitation,and population.Undertaking detailed investigation in rural areas is of great significance for development of rural society,scientific administration of the Communist Party of China,and the construction of the socialist society with Chinese characteristics.
文摘The purpose of this study is to reach a better understanding of how minor psychological problems (MPP) are perceived in China by well-educated Chinese. An exploratory qualitative design is used. The results are based on interviews with professionals and students practicing Chinese medicine (TCM) and lay people from three urban sites. Minor psychological problems have traditionally not been labelled as disorders or illnesses but challenges in daily living or as “heart problems” and seemed to have less serious consequences than we are accustomed to think from a modern western outlook. “Problems of life” rather than sickness was the category that best summarized perceptions of such problems among the Chinese. It points to a salutogenetic perspective reflecting perception of mental health and MPP as processes of adaption and interpretation of meaning rather than medical conditions or sickness. Due to the influence from the West these problems are, however, more often comprehended as a health problems or even sickness, and not solely natural problems of life.

文摘In this study, we adopt an improved Bayesian approach based on free-knot B-spline bases to study the spatial and temporal distribution of the b-value. Synthetic tests show that the improved Bayesian approach has a superior performance compared to the Bayesian approach as well as the widely used maximum likelihood estimation (MLE) method in fitting the real variation of b-values. We then apply the improved Bayesian approach to North China and find that the b-value has a clear relevance to seismicity. Temporal changes of b-values are also investigated in two specific areas of North China. We interpret sharp decreases in the b-values as useful messages in earthquake hazard analysis.
文摘As a prominent journalist and entrepreneur living in Shanghai from 1911 to 1937,the“China Hand”Carl Crow(1884-1945)wrote a lot of works on Chinese newspapers,business,religion and culture.His advertising agency Carl Crow,Inc.published four editions of Newspaper Directory of China in the year of 1921,1931,1932 and 1935 respectively,and the most popular was the edition of 1935,which had a positive impact on the commercialization and development of the China’s newspaper industry.

文摘After the founding of People’s Republic of China in 1949,the economic development philosophies of the Communist Party of China(CPC)evolved over time.Review of this difficult journey of ideological change can not only shed light on the origin,but also better understand the theoretical contributions of Xi Jinping thought on China’s socialist economy in the new era.This paper investigates China’s evolving economic development thoughts from six dimensions in three eras when the Chinese nation(i)independently established a basic industrial system from a blank sheet,(ii)sought prosperity through reform and opening up,and(iii)increased national strength.The six dimensions of this study include:(i)the tasks identified by the Party as essential for various stages of development;(ii)the different modes of economic development embraced based on development thoughts for various stages;(iii)the different modernization pathways to achieve the goals of socialist modernization;(iv)the adjustment of agricultural policy and development paths to close the urban-rural divide;(v)the different approaches for regulating the supply side and demand side of economic development with the emphasis changing across various stages;and(vi)the different emphasis to internal and external economic circulations across various stages.
