基于生态足迹模型的矿区可持续发展评估——以神木县为例

运用生态足迹模型对陕西神木县2007年的生态足迹进行了计算和分析,分别以神木县总能源消费量（包括工业生产能源消费和非工业生产能源消费）和以非工业能源消费量计算了其生态足迹,前者生态赤字达17.058 ha/cap,后者生态盈余为0.209 ha/cap,说明神木县生态赤字主要来源于工业能源消费,即是通过高能耗产品将其他地区的生态足迹转移到了神木县。最后根据生态足迹分析结果,提出了关于神木县可持续发展的建议。

Report of the Treasurer: 1981. The end of a treasurership!

I am beginning to believe in the myth that all good things must come to an end as I near the end of my tenure (nine years in all) as APA treasurer. It has been my distinct pleasure to serve the APA membership in this capacity during a period when APA's "net worth" has increased from $1,043,732 in 1973 to $2,417,666 in 1980. In fact, by the time I officially leave this office, our net worth will be approaching the $3 million plateau. To put this growth in net worth in perspective, it took about 82 years for APA to build its net worth to $1,043,732, while it has only taken nine years (1973-1982) to go from $1,043,732 to nearly $3,000,000. This solidification of APA's financial foundation has been accomplished during a period in our economy when double-digit inflation rates have been commonplace. It has only been possible with the universal support of the entire APA governance system, including the special efforts of the Board of Directors, the Finance Committee, the Investment Committee, the executive officer, and the Central Office management team. This article provides an in-depth look into the recent financial success of APA. Topics discussed include: information concerning revenues for 1980, the expected surplus of 1981, and future budget plans for 1982. (PsycINFO Database Record (c) 2010 APA, all rights reserved)

热电联产机组乏汽余热利用项目可行性分析

汽轮机余热利用项目前在国内已经有小范围应用,该项目采用吸收式热泵技术对汽轮机乏汽余热进行利用,用于集中供热,提高电厂供热能力,并且达到节能减排的目的。在调研和考察的基础上,通过可靠性和经济性论证,认为该方案在工艺技术上是可行的。     

发电侧电力市场结算方法比较研究

运用博弈论中的一级密封价格拍卖原理,构建了发电商在竞价上网中按市场边际出清价结算和按机组实际申报价格结算两种不同结算方式下的最优策略博弈模型,从而得到不同的最优报价策略,随后比较了在两种不同报价策略下市场交易的社会总剩余(福利)的变化。分析结果表明在按机组实际报价的结算方式下会导致社会福利的净损失。     

利用系统剩余容量评估电力市场中长期金融风险

电力市场中的中长期金融风险由于时间跨度较长,可能给市场参与者带来更为严重的损失,因此对其准确评估具有重要的现实意义.但是电价和供求这两个风险因子之间的强相关性使得蒙特卡罗方法无法直接应用于电力市场风险计算.系统剩余容量百分比反映了系统的电力供求状况,能够较好地解决相关性问题.本文引入剩余容量百分比与电价的关系曲线,以周数据为基础,应用蒙特卡罗方法,建立了月份、季度等中长期金融风险的评估模型,并结合浙江电力市场运行数据进行评估.计算结果表明该模型是有效的,预测结果和实际情况比较吻合.本文建立的模型具有较好的实用性,对防范和控制电力市场中长期金融风险具有参考价值.
