Entrepreneur environment management behavior evaluation method derived from environmental economy

Evaluation system can encourage and guide entrepreneurs, and impel them to perform well in environment management. An evaluation method based on advantage structure is established. It is used to analyze entrepreneur environment management behavior in China. Entrepreneur environment management behavior evaluation index system is constructed based on empirical research. Evaluation method of entrepreneurs is put forward, from the point of objective programming-theory to alert entrepreneurs concerned to think much of it, which means to take minimized objective function as comprehensive evaluation result and identify disadvantage structure pattern. Application research shows that overall behavior of Chinese entrepreneurs environmental management are good, specially, environment strategic behavior are best, environmental management behavior are second, cultural behavior ranks last. Application results show the efficiency and feasibility of this method.     

区域大气环境容量资源优化利用的博弈分析

大气环境容量是一种公共资源,合理利用和保护大气环境容量资源是大气环境改善的有效途径.从区域内各城市间的博弈行为出发,利用个人决策模型、整体决策模型、关系模型对区域内大气容量资源进行分析,揭示大气容量资源被过度使用的现象,针对城市监管不力、企业排污严重引起大气污染问题而提出帕累托改进模型,指出大气环境保护需要合作机制,联防联控.     

模型模拟在城市SO2环境容量测算中的应用研究

以许昌市污染源普查数据为基础,通过现状排放、环境质量控制目标与预测环境质量、污染物削减和浓度贡献分析,核定得到了准确可靠的许昌市二氧化硫环境容量;研究建立的从宏观理想容量到实际容量的多源模型体系,能较好地应用于二氧化硫环境容量研究;A—P值法、AERMOD模型均能较好地模拟污染源与环境空气质量的响应关系,且二者具有较好的一致性,可作为可靠的多源模型广泛应用于中小城市的二氧化硫环境容量核定研究及环境规划管理。     

能源承载力预测分析方法的研究与应用研究

能源需求和人口、经济密切相关。能源需求分析是在一定的人口和经济增长假设下进行的。从投入产出角度看,能源需求的高低取决于终端需求与满足终端需求的中间过程。经济结构的变化,经济增长模式的选择,技术进步,优质能源的可获得性,环境保护要求等因素会对终端需求和中间过程产生影响。由于资源对国家和地区的重要性,资源承载力的研究显得尤为重要。因此有必要对一个区域的能源需求量作出预测和分析,提高区域发展和管理的科学性,从而实现区域的可持续发展。

备件优化理论分析与应用研究

备件是综合保障工作的重要内容,是影响战备完好性的重要因素。备件优化就是在有限的经费支持条件下,最大限度使区域乃至全局武器系统战备完好性达到最优化。备件优化工作是建立在对武器系统保障模式、使用维修模式充分了解的基础上进行的。对多维修、多层次保障下备件优化进行理论分析,并利用OPUS10软件对陆航某型机组成的区域武器系统进行了应用分析。     

一种新型生物絮凝剂FM-2絮凝特性及稳定性考察

文章对絮凝剂FM-1的储存稳定性以及絮凝活性分布进行了考察,发现其絮凝活性物质主要分布于上清液之中,加之储存稳定性较差的特点,为絮凝剂FM-2的制备提供了前提。絮凝剂FM-2的最佳絮凝率高达99.21%,其储存时间较长,30 d内其絮凝率可保持在90%以上;而且还具有较好的热稳定性,当加热温度从70℃升高到100℃,其絮凝率均保持在95%以上。     

辽河保护区治理与保护能力建设研究

辽河保护区治理与保护能力的建设,通过界碑、围栏、标示牌、宣传牌等设施建设,重点区域的水质、生态监测站点建设,保护区综合管理平台建设,应急保障体系建设,形成保护区完善的综合监控网络体系,全面提高保护区基础设施与监控能力。同时,应使全民参与对＂母亲河＂的保护。     

基于排队论的城市垃圾箱最佳间距研究

针对城市垃圾箱最佳间距的研究不够精细的现状,本文通过建立排队论模型得到了可供不同城市参考的城市垃圾箱最佳间距参数表。通过对部分城市街道的垃圾箱摆放间距情况进行实地调查,运用层次分析法将影响垃圾箱间距分布的多重因素转化为单因素;建立了基于指数分布的教学模型,利用排队论分析单因素状态下的垃圾箱间距分布,得到了求解城市垃圾箱最佳间距的一般方法。     

Assessing field vulnerability to phosphorus loss in Beijing agricultural area using Revised Field Phosphorus Ranking Scheme

Guanting Reservoir,one of the drinking water supply sources of Beijing,suffers from water eutrophication.It is mainly supplied by Guishui River.Thus,to investigate the reasons of phosphorus(P)loss and improve the P management strategies in Guishui River watershed are important for the safety of drinking water in this region.In this study,a Revised Field P Ranking Scheme(PRS)was developed to reflect the field vulnerability of P loss at the field scale based on the Field PRS.In this new scheme,six factors are included, and each one was assigned a relative weight and a determination method.The affecting factors were classified into transport factors and source factors,and,the standards of environmental quality on surface water and soil erosion classification and degradation of the China were used in this scheme.By the new scheme,thirty-four fields in the Guishui River were categorized as"low","medium"or"high"potential for P loss into the runoff.The results showed that the P loss risks of orchard and vegetable fields were higher than that of corn and soybean fields.The source factors were the main factors to affect P loss from the study area.In the study area,controlling P input and improving P usage efficiency are critical to decrease P loss.Based on the results,it was suggested that more attention should be paid on the fields of vegetable and orchard since they have extremely high usage rate of P and high soil test of E Compared with P surplus by field measurements,the Revised Field PRS was more suitable for reflecting the characteristics of fields,and had higher potential capacity to identify critical source areas of P loss than PRS.
