Mineral Resource Science in China:Review and perspective

Mineral resources are essential to prosperity and security of modern societies.How mineral resources can guar-antee sustainable development of economy in countries,especially those developing countries,has long been a focus of attention of international communities.This paper provides a comprehensive summary for major ad-vance of the research on mineral resources in past decades,and proposes some key issues regarding ore-forming mechanism,exploration and utilization of major and critical mineral resources.On the basis of these aspects,we also identify four priority science issues to be addressed in the future,including(1)mechanism of both metal circulation and extremely high concentration,(2)theories and technologies of prospecting deep-earth resources,(3)investigation of mineral resources in seafloor and polar regions,and(4)efficient,clean and recycling utiliza-tion of mineral resources.It can be expected that new advances in these four issues would tremendously promote the innovation of mineral resource science,and provide scientific and technologic support to meet the demand of mineral resources for human activities and the harmonious development of both mineral-resource exploration and ecological restoration.

Spatial Disparity and Efficiency of Science and Technology Resources in China

In the knowledge economy era,science and technology(S&T) resources are getting more and more important in shaping regional competiveness and building regional innovation capacity.As such,the spatial distribution of S&T resources is a key to understanding regional development and disparities.By designing an input-output indicator system,this paper develops an evaluation model to examine the spatial distribution of S&T resources in China and assess their spatial efficiency.Moreover,the paper tries to explain spatial differences in the efficiency of S&T resources in China.Major findings are:1) the input and output of S&T resources in China shows a clear T-shaped spatial structure,i.e.,concentrated mainly in the coastal region and along the Changjiang(Yangtze) River;2) the efficiency of S&T resources in China displays strong spatial disparities,with the level of efficiency descending from the east to the west while high efficiency appearing in only several clusters;3) the utilization rates of S&T resources in most provinces are quite low,resulting in low efficiency of S&T resources allocation.The paper suggests that the utilization rate of S&T resources should be raised and the commercialization of S&T outputs should be enhanced to improve the efficiency of S&T resources in China.

Institute of Geographic Sciences and Natural Resources Research, CAS

Institute of Geographic Sciences and Natural Resources Research (IGSNRR) was established in late 1999 on the basis of the consolidation of two former CAS institutions: the Institute of Geography and the Commission for Integrated Surveys of Natural Resources. With an aim to promote the coordinated development between population, resources, economy and the environment, the IGSNRR strives to serve the nation’s major needs in resource and the

Graduate education of library science in China:Current status and recommendations for improvement

More than twenty years ago,Wuhan University and Nanjing University offered library science(LS)graduate programs.Since then,LS graduate education has been growing quickly in many aspects.At the same time,however,LS graduate education was also facing enormous challenges stemming from the dynamic development and wide applications of information technologies into the pedagogical arena of teaching and learning at all levels.Social evolution also made it necessary for LS educators to re-examine once again their graduate education model,curricular composition,educational philosophy and educational missions.In analyzing the present situation of LS graduate education in China,this paper focuses on the following issues:1)Growing size of LS graduate education(quantity and quality);2)educational objectives,including research direction and placement for graduates;3)structure of knowledge and curricular construction;4)conditions of administering a library school of high quality and 5)the management of teaching resources.The keystone of this paper is to pinpoint where current library science curricular deficiencies are lying.It is hoped that more serious scholarly discussions and perhaps also even concerted efforts among LS scholars and library practioners may be evoked in having the graduate education system of library and information science thoroughly realigned for the informational needs of the 21st century.

The measure and characteristics of spatial-temporal evolution of China＇s science and technology resource allocation efficiency

According to the connotation and structure of science and technology resources and some relevant data of more than 286 cities at prefecture level and above during 2001-2010, using modified method--Data Envelopment Analysis （DEA）, science and tech- nology （S＆T） resource allocation efficiency of different cities in different periods has been figured out, which, uncovers the distributional difference and change law of S＆T resource allocation efficiency from the time-space dimension. Based on that, this paper has analyzed and discussed the spatial distribution pattern and evolution trend of S＆T resource allocation efficiency in different cities by virtue of the Exploratory Spatial Data Analysis （ESDA）. It turned out that： （1） the average of S＆T resource allocation efficiency in cities at prefecture level and above has always stayed at low levels, moreover, with repeated fluctuations between high and low, which shows a decreasing trend year by year. Besides, the gap between the East and the West is widening. （2） The asymmetrical distribution of S＆T resource allocation effi- ciency presents a spatial pattern of successively decreasing from Eastern China, Central China to Western China. The cities whose S＆T resource allocation efficiency are at higher level and high level take on a cluster distribution, which fits well with the 23 forming urban agglomerations in China. （3） The coupling degree between S＆T resource allocation efficiency and economic environment assumes a certain positive correlation, but not completely the same. The differentiation of S＆T resource allocation efficiency is common in regional devel- opment, whose existence and evolution are directly or indirectly influenced by and regarded as the reflection of many elements, such as geographical location, the natural endowment and environment of S＆T resources and so on. （4） In the perspective of the evolution of spatial structure, S＆T resource allocation efficiency of the cities at prefecture level and above shows a notable spatial autocorrelation, which in every period presents a positive correlation. The spatial distribution of S＆T resource allocation efficiency in neighboring cities seems to be similar in group, which tends to escalate stepwise. Meanwhile, the whole differentiation of geographical space has a diminishing tendency. （5） Viewed from LISA agglomeration map of S＆T resource allocation efficiency in different periods, four agglomeration types have changed differently in spatial location and the range of spatial agglomeration. And the conti- nuity of S＆T resource allocation efficiency in geographical space is gradually increasing.

The Gray Relevancy Research on New Products Output and Science ＆ Technology Resources input in State-owned industrial Enterprises

This paper analyzes the correlativity between new products output and science ＆ technology resources input by the method of Gray Relevancy model, and finds that the spending for new products has greatest correlativity with new products output in large and medium sized state-owned industrial enterprises.

Quantitative characterization and comprehensive evaluation of regional water resources using the Three Red Lines method

Based on the synergetic development of new industrialization, rapid urbanization and agricultural modernization(IUAM), and from the viewpoint of interactive relationships between water resources and regional population, eco-environment, economy and society, the concepts of water resources intensity(WRI), water environment intensity(WEI), water resources relative efficiency(WRRE) and water environment relative efficiency(WERE) are defined with reference to energy intensity, resources efficiency and environment efficiency theory. On the basis of benchmarking theory, the quantitative characterization and evaluation method of "Three Red Lines"(the upper limit of water resources allocation, the baseline of utilization efficiency of water resources and the upper limit of sewage discharge) is proposed. According to these concepts and models, an empirical analysis of the Three Red Lines of water resources on the Chinese mainland between 2003 and 2012 was carried out. The results showed that total water consumption in eastern, central and western parts of China possesses "club convergence" characteristics, which means these areas have similar internal conditions appeared convergence in the development. Inter-provincial differences in water consumption continue to decrease, but the north–south differentiation characteristics in the eastern and central regions were still relatively obvious, while provincial differences in the eastern part were at a minimum and the central region had the largest. Water Resources Efficiency(WRE) of all four sectors in the Southwest rivers and Huaihe River basins were generally high. Industrial WRRE in the Songhua River, Yangtze River and Pearl River basins, agricultural WRRE in the Songhua River, Yellow River and northwestern river basins and domestic WRRE in the Liaohe River, Yangtze River and Pearl River basins were all low. Eco-environmental WRRE in the southeastern rivers and Yangtze River basins were low but showed an upward trend. Other river basins, except for the Northwestern rivers basin, had high eco-environmental WRRE with a downward trend. Western China, especially the northwestern part,had a low relative intensity of the water environment(WERI) and high integrated water environment management(IWEM) performance, but the relative intensities of the water resources(WRRI) were fairly high, and the comprehensive performance of integrated water resources management(IWRM) in these regions was low. In southern China, especially the southeastern part, the IWEM was fairly high, but the overall IWRM was lower.
