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。     

Effect of Mountain Relief and Industrial Air Pollution on Biometric Characteristics of Pine Stands

The effect of mountain relief and industrial air pollution on biometric parameters of pine stands was studied. The empirical–statistical models of the dependence of biometric characteristics on the parameters of forest sites were developed using raster modeling and multivariate analysis. The possibility of predicting changes in the biometric parameters at any site on the basis of these models is shown.     

项目决策阶段清洁生产分析方法的研究

企业在建设项目决策时就应该按照清洁生产的原则，从源头控制污染。提出了在项目决策中，应从产品选择、工艺路线选择、主要设备选型和节能降耗4个方面进行清洁生产的分析方法，通过此分析方法的应用，可以避免项目决策中的环境失误和降低企业的环境风险。     

生态社区综合评价指标体系的初步探讨

生态社区的出现和发展一直广受关注，建立生态社区综合评价指标体系对于生态社区的实践和发展具有重要的意义。本文通过对社区可持续发展理论，生态平衡理论以及生态社区本身系统特点的探讨，尝试建立一个综合评价指标体系，同时对评价指标体系应体现的功能，以及评价指标体系构建的原则做了初步探讨。     

太湖饮用水源地蓝藻水华预警监测体系的构建

从预警机制的建立与分工、预警监测时间的确定、预警监测的启动、预警信息的发布、预警监测的终止、预警监测的工作流程等方面，建立了太湖引用水源地蓝藻水华预警监测体系。指出了政府必须在资金、物资、人才、技术等方面给予预警监测体系充足的保障，确保预警监测体系长期有效地运行。     

废水产氢产酸/同型产乙酸耦合产酸条件优化

为了更好地发挥产氢产酸/同型产乙酸耦合系统在废水厌氧发酵生产乙酸方面的优势,有必要寻找一种简单有效的方法以获得该系统产酸的优化条件.利用经过加热处理并活化的厌氧污泥作种泥,以模拟废水中的葡萄糖为底物,针对发酵时间、底物浓度、种泥浓度、初始pH进行4因素10水平均匀设计实验,得到了乙酸生产指标与产酸条件之间关系的回归方程;也得到了以高乙酸产量为主要目标导向同时兼顾高乙酸产率和高乙酸生产强度目标的优化条件;优化条件实验乙酸浓度比均匀设计中最高乙酸浓度提高20%左右.研究表明,将均匀设计应用于废水产氢产酸/同型产乙酸耦合产酸条件优化,可以避免盲目性,迅速获得满意结果.     

生态型港口综合评价指标体系初探

基于上海市建设生态型城市的长期目标，将港口作为城市生态系统中重要的子系统，对如何建设生态型港口提出了综合评价指标体系。通过筛选得到45项单因素指标，针对不同类型的港区有所分异，整个评价体系分为5个准则层（生态环境、经济效率、污染控制、环境管理、社会评价）和10个因素层（大气/声环境、生物资源、基底质量、经济发展、生产效率、循环经济、污染排放、清洁生产、环保投入、社会参与），并采用AHP（层次分析）法确定了各层次的权重分配。进而根据2005年上海港年均生产状况和2006年上半年的港区环境－资源调查，尝试对上海港7种主要类型（集装箱、件杂货/成品、多用途、干散、粮食港区、液散、客运）的15个港区进行了现状评估。然而，生态港评价系统的指标选取、权重制定、评估级别等实践与完善仍需要多学科和政府职能部门的参与。最后，项目还提出了水生态健康、航道淤积、生态风险、水陆景观等非定量生态港评价因子。     

On Index System and Quantitative Assessment of Eco-cities： A Case Study on Urban Agglomeration of the Yangtze Delta

Urban agglomeration of the Yangtze Delta （UAYD）, one of the most developed regions of China, has witnessed an increasing prevalence in building ecological cities when the ecological cities are pursued by many modem cities, and great achievements have been made in this regard. It is inevitable, however, that certain problems exist during the construction of ecological city, which include but not limited to non-harmonious development of urban complex ecosystem, and the difficulty in quantifying eco-city construction or incomplete quantification in assessing the construction of present and future eco-city. Based on the analysis on social-economic conditions and regional conditions of the UAYD, this paper attempts to set up an index system of eco-cities combining with local characteristics, and to adopt the indices of eco-city, urban harmony, and eco-city colligate to evaluate the ecological level, urban harmonious development and eco-city construction of cities within the UAYD. Results indicate that among 15 cities in UAYD, Suzhou City ranks the highest in terms of eco-city construction, whereas Nantong ranks relatively lower; sustainable eco-city construction is possible only when cities are developed in every respect of harmony.     

现行财税体制下我国耕地资源数量变化的实证研究

耕地资源数量变化受到人口、经济等诸多因素的影响，而财税体制是影响耕地资源数量变化的更深屡次原因。通过数量关系的初步观察和作用机理分析说明我国现行财税体制对耕地资源数量变化存在正反两方面作用，总体来看，对耕地资源保护不利。计量结果进一步证实了我国现行财税体制对耕地资源数量变化存在显著影响。揭示了其影响的方向和大小。根据研究结果，文章有针对性地提出了增加地方财政预算收入，合理分配土地出让金比例和科学使用土地出让金等相关政策建议。     

Comparison of models of simazine transport and fate in the subsurface environment in a citrus farm

Contamination of groundwater by agrochemicals is now widely recognized as an extremely important environmental problem. Modern agricultural practices involve the combined use of irrigation with the application of large amounts of agrochemicals to maximize crop yield. Due to flood irrigation and natural runoff, agricultural activities might generate soil, surface water and groundwater contamination problems and leaching of pesticides. Modeling of the transport and fate of pesticides, such as simazine, may help understand the long-term potential risk to the subsurface environment. This paper illustrates a comparative study via the use of three different pesticide transport simulation models and the applicability of those models in determining the groundwater vulnerability to pesticides contamination in a citrus orchard located at the Lower Rio Grande Valley (LRGV). The three models used in the study are the pesticide root zone model-3 (PRZM-3), the pesticide analytical model (PESTAN) and integrated pesticide transport modeling (IPTM). The concentration values obtained from all three models are in agreement, and they show a decreasing trend from the surface through the vadose zone. The problem is how to use this information and, specifically, how to combine the testimony of a number of experts into a single useful judgment. With the aid of the fuzzy multiattribute decision making method, PRZM-3 is deemed as the most promising one for such precision farming applications.
