基于地震灾害风险形成机理,在建立人口震害脆弱性曲线与确定地震发生参数的基础上,本文利用评估模型对我国Ⅴ-Ⅺ地震烈度下各县域单元的人口死亡风险进行评估并分析其空间分布格局。主要研究内容有:(1)首次采用基于过去—现在—未来的多方面地震孕灾环境资料来处理地震发生的可能性。具体综合历史地震综合烈度、地震活动断裂带分布、地震动峰值加速度三方面来确定全国2355个县域单元的地震发生参数;(2)利用1990-2009年我国历史地震灾情数据,对地震烈度与人员死亡率之间进行线性拟合,建立适合我国地震灾害风险评估的震害人口死亡脆弱性曲线;(3)利用震害风险评估模型对我国各县域单元的人口死亡风险进行定量评估,并分析风险空间分布格局,彻底摸清Ⅴ-Ⅺ地震烈度下我国各县域单元的地震灾害人口死亡风险。研究表明:在不同地震烈度下,我国广大的东、中部地区面临更高的风险,而西部的人口死亡风险相对较低。高风险区域呈零星状分布于山东与江苏大部、安徽北部、黑龙江与吉林东部等人口分布较密集且孕灾环境发育完备的区域。而无风险区域在全国范围内呈斑块状散布,分布格局基本保持不变。     

中国干旱灾害评估与空间特征分析(英文)

Based on the monthly precipitation data for the period 1960-2008 from 616 rainfall stations and the phenology data of main grain crops,the spatial characteristics of drought hazard in China were investigated at a 10 km×10 km grid-cell scale using a GIS-based drought hazard assessment model,which was constructed by using 3-month Standard Pre-cipitation Index (SPI).Drought-prone areas and heavy drought centers were also identified in this study.The spatial distribution of drought hazard in China shows apparent east-west dif-ference,with the eastern part of China being far more hazardous than the western part.High hazard areas are common in the eastern and central parts of Inner Mongolian Plateau,the central part of Northeast China Plain,the northern part of Heilongjiang,the southeastern part of Qinghai-Tibet Plateau,the central and southern parts of Loess Plateau,the southern part of North China Plain,the northern and southern parts of Yangtze River Plain,and Yun-nan-Guizhou Plateau.Furthermore,obvious differences in drought hazard were found both within and between different agricultural zonings.     

环境伦理与区域可持续发展(英文)

The scientific environmental ethics plays a key role in the recognition of the human-environment interactions. Modern environmental ethics is the philosophical re-thinking of modern human race environmental behavior. The development of environmental ethics theory, as well as its application in reality, determines the viewpoints of environmental ethics. Sustainable development implies harmony on human-environment interactions and inter-generation responsibility, with emphasis on a harmonious relationship among population, resources, environment and development, so as to lay a sustainable and healthy foundation of resources and environment for future generations. The harmonious society construction in China that is raised by the Chinese central government should be covered by environmental ethics. The connotation of open environmental ethics includes a respect for nature, care for the individual human race, and respect for the development of future generations, which means giving consideration to natural values, individual and human race benefits and welfare across generations. The role of environmental ethics in regional development consists of cognition, criticism, education, inspiration, adjusting, legislation and promoting environmental regulations. The major problems in regional development are extensive resource exploration, fast population growth, irrational industrial structure, unfair welfare distribution and the twofold effects of science and technology development. The formulation of environmental ethics that aims at regional sustainable development, can not only harmonize the relationship of population, resource, environment and economic development, but also guide behavior selection, push social and political system transformation, strengthen the legal system, and raise environmental awareness of the public.     

中国土壤盐渍化研究的现状及未来(英文)

With the environmental deterioration caused by the advance of climate change, soil salinization is a serious and growing global problem. Currently about 7% of the world's land surface is threatened by salinization. China is a country whose soils are severely affected by this problem, which, due to its extensive area, and wide distribution poses a serious threat to regional agricultural development. In this review, we summarize the framework for soil salinization research in China over the past 70 years, assess the weaknesses of existing research in both a domestic and international context, highlight the trends and key findings of global research about saline soils over the past 30 years, and propose six major fields and directions for future research on saline soil.

中国城市群分布及范围的定量评价(英文)

Urban clusters are the expected products of high levels of industry and urbanization in a country, as well as being the basic units of participation in global competition. With respect to China, urban clusters are regarded as the dominant formation for boosting the Chinese urbanization process. However, to date, there is no coincident, efficient, and credible methodological system and set of techniques to identify Chinese urban clusters. This research investigates the potential of a computerized identification method supported by geographic information techniques to provide a better understanding of the distribution of Chinese urban clusters. The identification method is executed based on a geographic information database, a digital elevation model, and socio-economic data with the aid of ArcInfo Macro Language programming. In the method, preliminary boundaries are identified accord-ing to transportation accessibility, and final identifications are achieved from limiting city numbers, population, and GDP in a region with the aid of the rasterized socio-economic dataset. The results show that the method identifies nine Chinese urban clusters, i.e., Pearl River Delta, Lower Yangtze River Valley, Beijing-Tianjin-Hebei Region, Northeast China Plain, Middle Yangtze River Valley, Central China Plains, Western Taiwan Strait, Guanzhong and Chengdu-Chongqing urban clusters. This research represents the first study involving the computerized identification of Chinese urban clusters. Moreover, compared to other related studies, the study’s approach, which combines transportation accessibility and socio-economic characteristics, is shown to be a distinct, effective and reliable way of identifying urban clusters.

中国城乡用地集约利用定量测度与影响机理(英文)

Land use issue is an important constraining force to limit economic sustainable development of China. Urban and rural rapid expansion depletes valued land resources under the background of rapid urbanization. An extensive use pattern might cause a serious waste of land resources. The study on influencing mechanism of land intensive use(LIU) in China at the county level is a key tool for effective LIU practice and policy-making. This paper uses OLS model, Spatial Panel Lagged model and Spatial Panel Error model to quantitatively analyze the influencing mechanisms of five class factors and 17 variables supported by GIS(Geographic Information System) and MATLAB. And a comprehensive data set was developed including physical geography and socio-economic information of 2286 counties. Meanwhile, the spatiotemporal pattern of LIU has discussed by means of GIS. The results show that Spatial Panel Data models are slightly superior to OLS model in terms of significance and confidence level. Regression results of these models indicate that industrialization, urbanization, economic development level, location, transportation and policy have significant impact on LIU of counties. The variables of physical geography are less significant than socio-economic variables. An ignored variable of historical factor, however, became the best significant factor. In the future, the LIU at the county level should take advantage of the new situation by enhancing favorable factors and reducing disadvantageous ones, which can be acquired by improving the entire level and quality of industrialization and urbanization. We argued that an efficient and complete land market and operating system should be built to reflect market-oriented activities at the first place, then, differential LIU regulation policies and measurements should be optimized according to regional differences. In the meantime, we should pay close attention to the carrying capacity of local resources and environments when conducting LIU practices.     

书评——《城市对称分布与中国城市化趋势》(英文)

YE Danian, HE Wei, LI Zhe, XU Wendong Anhui Education Press,Hefei,2011,x+260 pp,ISBN 978 7 5336 5737 6(hardback),CHY 58.00 As products of urbanization, cities are focal points for social and economic interaction. Though China is an ancient civilization, only recently has the urban population surpassed that in rural areas. During the last three decades, unprecedented urbanization has reshaped China’s geographical, social, economic and cultural landscapes. Among the social-economic transformations having occurred in China in recent history, urbanization is probably the most impressive and dynamic process; it has changed daily life of Chinese population and profoundly impacted the regional and global economy.     

熵视角下的广州城市生态系统可持续发展能力分析(英文)

The urban ecosystem possesses dissipating structures that can absorb substances and energy from the external environment and export products and wastes to maintain order within the system. Given these circumstances, this paper analyzed the ability of the urban ecosystem in Guangzhou City to sustain development from the perspective of entropy. The research was carried out in three steps. First, an evaluation index system that considers the ability of the urban ecosystem for sustainable development was formed based on the structures and functions of the urban ecosystem and the change in the entropy of the urban socioeconomic ecosystem. Second, the sustainable development ability assessment model for the urban ecosystem was built using information entropy. Last, by combining the time series variation of the evaluation indicators with the entropy weights, this paper analyzed the influence of the combined factors on the sustainable development ability of the urban ecosystem in Guangzhou and suggested some measures to promote the sustainable development of the urban ecosystem in Guangzhou. The conclusions of this study can be summarized as follows: (1) The urban ecosystem has developed in an orderly and healthy direction, with effective control over the urban environmental pollution problems in Guangzhou between 2004 and 2010. (2) The sustainable development ability of the urban ecosystem had been on an upward trend in Guangzhou during the study period. The ability of the natural urban ecosystem to support the urban socioeconomic ecosystem increased continuously, and the improved ecoenvironment enhanced the harmony and vitality of the urban ecosystem in Guangzhou.

实现纤维素生物质能源的可持续发展(英文)

生物质是一种丰富易得的清洁能源,具有大幅减少温室气体排放的潜力。与以玉米及其他谷物为原料的生物质能源生产技术相比,由于纤维生物能源生产消耗的化石能源较少(化石能源与碳的比值低)而备受关注。然而,生物燃料生产系统并非简单,受到多种因素的影响,如能量供应、农村的经济发展水平、土地和生态系统的保护、温室气体减排的可能性以及社会培训等。本文简要综述生物质能源开发的经济与环境影响。根据区域气候和生态条件,不同地区具有各自的生物质种类或能源作物的优化组合。在不久的将来,生物质能源开发的生物技术所面临的挑战包括:生物质形成与细胞壁分解过程的认识与操控,生物质预处理技术,糖产量高的植物变种的选育,用于纤维素降解的酶和微生物的大规模筛选与选育等。除强调生物质能源开发的环境安全和公共健康的重要性之外,生物质能开发还需要解决生命周期评价(LCA)、可持续性的标准和指标的建立等问题。     

中国自然遗迹类保护区的保护有效性评估(英文)

Evaluating the effectiveness of protecting nature assets is a vital component of responsive, pro-active management of protected areas. It is important to protect reserves of geological(including fossils) assets as a means to also protect national and natural heritage. At the end of 2013, 2669 protected areas had been established in China and 123 of them are reserves for nature assets. This paper builds an evaluation framework for protection effectiveness of these assets. The current elements and characteristics for effective protection are analyzed, along with an analysis of existing problems so as to construct a scientific approach to protect these assets. The influencing elements and characteristics for effective protection of nature asset reserves are included in an index evaluation system for effective protection in such areas, which contains four parts–target layer, evaluation criteria, evaluation indexes, and evaluation parameters–based on related documents and files. For the target layer, it includes nature asset evaluation and management evaluation. In the end, it is discussed how to build a comprehensive evaluation model and achieve an effective quantitative evaluation.     

基于粮食安全的中国能源可持续发展:机遇和挑战(英文)

中国能源安全形势日益严峻,机遇与挑战并存。生物质能发展具备资源丰富、产品多元化、循环利用和增加农民收入的显著优势,加快生物质能开发对保障中国能源供给安全极为重要。本文通过运用灰色关联分析方法,对中国生物质能开发与粮食安全之间的关系进行定量评价。结果显示我国生物质能开发对粮食安全的影响并不明显,中国的粮食安全主要受其农业生产条件限制。但这并不意味着中国生物质能可以不受限制的发展,中国发展生物质能需综合平衡多种因素,如短期内大量投资、生物质供应的激烈竞争。清洁、可持续是中国生物能源发展的重要方向。

皇甫川流域降水量和人类活动对径流量变化影响的定量评估(英文)

The runoff of some rivers in the world especially in the arid and semi-arid areas has decreased remarkably with global or regional climate change and enhanced human activities.The runoff decrease in the arid and semi-arid areas of northern China has brought severe problems in livelihoods and ecology.To reveal the variation characteristics,trends of runoff and their influencing factors have been important scientific issues for drainage basin management.The objective of this study was to analyze the variation trends of the runoff and quantitatively assess the contributions of precipitation and human activities to the runoff change in the Huangfuchuan River Basin based on the measured data in 1960-2008.Two inflection points(turning years) of 1979 and 1998 for the accumulative runoff change,and one inflection point of 1979 for the accumulative precipitation change were identified using the methods of accumulative anomaly analysis.The linear relationships between year and accumulative runoff in 1960-1979,1980-1997 and 1998-2008 and between year and accumulative precipitation in 1960-1979 and 1980-2008 were fitted.A new method of slope change ratio of accumulative quantity(SCRAQ) was put forward and used in this study to calculate the contributions of different factors to the runoff change.Taking 1960-1979 as the base period,the contribution rate of the precipitation and human activities to the decreased runoff was 36.43% and 63.57% in 1980-1997,and 16.81% and 83.19% in 1998-2008,respectively.The results will play an important role in the drainage basin management.Moreover,the new method of SCRAQ can be applied in the quantitative evaluation of runoff change and impacts by different factors in the river basin of arid and semi-arid areas.     

基于能值的内蒙古可持续发展评价(英文)

An integrated environmental accounting of the Inner Mongolia Autonomous Region(IMAR) is presented in this paper based on emergy analysis with data from 1987 to 2007.Through calculating environmental and economic inputs and a series of emergy indicators,this paper discusses IMAR’s resource use structure,economic situation,and trade status.The results show that more than 85% of the emergy used in IMAR was derived from home sources,indicating a strong capacity for self-sufficiency.Concentrated-used local non-renewable emergy,which provides IMAR economy with most of the driving forces,took the largest share in total emergy use after 2004 and reached 58% in 2007.The Western China Development Plan of 2000 ushered in a rapid growth of coal and electricity production and exportation to other regions of China from IMAR.The export/import emergy ratio of IMAR reached 3.46 in 2007,with the coal exported(3.44 10 23 sej in 2007) without being used by IMAR itself,accounting for almost 100% of the difference between the imports and exports.The results also show that from 1987 to 1998,EmSI values remained higher than 10,suggesting underdevelopment in IMAR;after 1998,EmSI values decreased sharply from 19.07 in 1998 to 1.88 in 2007,indicating that IMAR is characterized by medium-run sustainability and is relying more on non-renewable resources and imports.
