企业需要建立人性化的安全管理

由于我国对企业特别是海外来大陆投资的企业，缺乏严格的安全管理手段，致使不少企业屡次出现安全事故。为了减少企业安全事故的发生，提高企业安全度，要求企业在贯彻“安全第一，预防为主”的基本方针的基础上。建立“以人为本。以制度和伦理道德为约束的人性化的安全管理系统”。本文给出了该系统的模型，并对此模型进行了分析和解释，探讨了相关的几个理论基础，最后给出了人性化安全管理的实质。通过该系统的管理执行，使企业在尊重人权、尊重生命的前提下发展壮大，最终实现安全的全球化。     

The Role of Foreign Direct Investment in Urban Environmental Management: Some Evidence from Hanoi, Vietnam

In recent years flows of foreign direct investment (FDI) to developing countries have rapidly been increasing. It is now an important contributor to the national economy and urban growth in scores of developing countries. Rapid urbanization in these countries is leading to many problems in the cities. Existing urban infrastructure and municipal services have been unable to cope with the increased demand arising from growing population and rapid economic growth. Consequently, the environment in these cities has deteriorated alarmingly. This paper assesses the role of FDI in urban environmental management (UEM) by analyzing the linkages between them for Hanoi City in Vietnam. The paper's analysis and findings are presented under three main themes: one, FDI, employment and income; two, FDI and environmental degradation; and three, potential of utilizing FDI for the provision of urban environmental infrastructure and services (UEI&S) in order to improve the urban environment. Both primary and secondary source data have been used. Policy implications of the research findings are drawn from the perspective of sustainable development.     

黄河流域水资源价值的计算与分析

利用经济杠杆的调节作用促使水资源的高效利用，是缓和水资源供需矛盾的有效措施之一。本文以水资源价值理论为基础，从黄河全流域水资源优化配置角度出发，以利用水资源获得最大经济效益为目标，测算了黄河水资源的理论价值，为制定黄河水资源费的征收标准提供科学的理论依据。     

三峡库区中低产土壤重金属含量及其与小麦吸收的关系

三峡库区中低产土壤的Hg,As,Cr,Pb,Cu五个重金属含量（除渝北区外），均在国家土壤环境质量标准内，属自然背景值一级标准。Cd和Zn高于全国土壤中的平均含量和背景值含量，属二级标准。土壤的重金属含量与土壤母质类型，pH值，阳离子交换量，有机质，无定形铁和物理性粘粒有关，同时存在一定的地域分布。重庆近郊的土壤所有重金属含量相对较高。土壤重金属的可给态或有效性含量极低，锌和铜不是过量，而是不足。小麦籽粒中As,Cr,Pb,Zn,Cu含量低于国家食品对重金属限量标准和小麦籽粒背景值标准，Hg,Cd含量高于国家规定标准。籽粒中的Cu,Zn含量是小麦茎叶中的2.0-2.2倍，而茎叶中的Hg,Pb,As,Cr,Cd含量明显高于籽粒。     

水资源条件约束下西北农村地区生态经济发展对策

西北地区生态脆弱，社会经济发展相对落后。农业在全区经济中占有重要的地位，所以农村地区可持续发展对于实现西北地区可持续发展具有重要意义。通过分析西北地区水资源现状及特点和本区农村社会、经济发展现状，认为西北地区水资源严重缺乏，干旱化趋势将长期存在；农业结构不合理，乡镇工业污染严重、城镇化进程缓慢是制约本区农村地区可持续发展的主要因素。在此基础上，提出了在水资源严重缺乏条件下西北农村地区实现生态经济可持续发展的具体对策：积极调整农业结构，大力发展节水农业和推进农业产业化；加强小城镇社区生态环境基础设施建设，实施城镇化发展战略和乡镇企业可持续发展；建设生态型的小城镇，建立农村地区新型生态能源结构，加强小流域综合治理是改善农村生态环境和实现农村地区生态经济可持续发展的有效途径。     

Fluctuations of Population Size and Structure in the Northern Mole Vole: Preliminary Analysis

Long-term stationary studies on the ecology of the northern mole vole (Ellobius talpinus Pall.), performed by the mark–recapture method from 1985 to 1997, have provided original data on population dynamics and structure. The analysis shows that, to reveal cyclic fluctuations of population size in this species, the period of three years should be taken as a unit of time for estimating the duration of one phase. The 12-year population cycle in E. talpinus has four distinct phases: an increase, a peak, a decline, and a minimum. At each phase, the population is characterized by certain features of family structure, age composition, birth and death rates, and the composition of migrants.     

湖北省土地资源遥感调查与评价

根据1999年TM影像解译了湖北省土地利用现状，然后以土地利用现状图为基础，采用地理信息系统技术，结合湖北省的实际情况，选择土壤、地形、坡度等评价因子，对湖北省土地资源进行了适宜性评价，简要地将全省土地资源划分为九等。评价结果表明：湖北省水热条件好，土地适宜性广，宜农林牧业同时利用的土地广泛分布；但是该省的基本农田面积小，土地垦殖率高，低产田面积大，后备耕地资源严重不足；土地利用结构与土地资源的供给条件、利用要求不相适宜，利用效益末得到充分发挥。     

Prioritization of Sustainable Groundwater Management Needs: The Case of the Israel's Stressed Coastal Aquifer

On-going population growth and resulting domestic demand for water require rapid and effective decision-making as regards groundwater management and control of the various sources of salinization and pollution in Coastal aquifers. Sustainability of water resources for utilization by future generations must therefore be a high priority, not only for the purpose of fulfilling needs for water usage but also for bringing people into harmony with their ambient natural environment.The objective of this paper is to propose an empirical approach for prioritization of the needs involved for sustainable aquifer management. The approach involves a schematic format to:(1) develop a global understanding of an aquifer's hydrological and environmental properties in order to delineate appropriate eco-hydrological scenarios and recommend corresponding operational management activities; and(2) emphasize the importance of educating and increasing the awareness of the population involved as to the need for and viability of socially acceptable measures for sustainable management of groundwater and other resources.The psychologist Abraham Maslow utilized a pyramid to illustrate that until people's most basic needs were fulfilled, higher levels of needs would remain irrelevant. This paper postulates a comparable pyramid prioritizing hydrological needs required for progressing towards sustainable groundwater resources. Two sub-regions of Israel's Coastal aquifer in the Sharon region have been presented as representative areas, each characterized by different stress of exploitation. In assessing these sub-regions situation, specific measures have been recommended for achieving and/or maintaining sustainable groundwater resources in light of the ambient environment, and the level of the population on the pyramidal hierarchy of groundwater needs.     

母岩的风化剥蚀速率与土壤允许流失量的关系 --以长江三峡坝区风化花岗岩土壤为例

土壤允许流失量的确定是一个非常复杂而又必须解决的问题，它关系到水土保持措施的布设和土壤的可持续利用。然而，发育在不同母质上的土壤，其土壤的最大允许流失量差异很大，确定这一值的依据也各不相同。在岩成土壤地区，母岩风化剥蚀速率的大小直接影响土壤的发育。是确定土壤允许流失量、分析人类加速水土流失的重要依据之一。选长江三峡黄陵背斜段风化花岗岩土壤为研究对象，根据剥蚀沉积相关原理，通过恢复古地理环境及时代，计算出新生代以来本区花岗岩的平均风化剥蚀速率为16．97mm／ka．最大剥蚀速率为49．56。又根据区内太平溪流域的泥沙资料，算出了当地现代的剥蚀速率，多年平均为297．7mm／ka，最小值为31．5mm／ka，而水利部颁布的当地土壤允许流失量为200t／km^2,a，折合为76．9mm／ka，二者相差近1．5—4．5倍。基于此。提出了确定土壤允许流失量必须参考母岩风化剥蚀速率的新观点。
