Detailed Ecological Footprint Accounting of Liaoning in 2006

Ecological footprint （EF） has received considerable attention as a useful indicator in the context of sustainable development. So far, EF has been used in numerous studies by academies, organizations and government authorities. However, the results of these studies failed to be comparable directly with each other due to imprecise data sets, unmodified accounting methods of pasture and fossil energy, ignored secondary products, undefined process Of calculating yield factors and improper biocapacity for biodiversity. In this paper, we elaborated on EF estimating methods from six categories of consumption in order to overcome the limitations above. We adopted precise data and revised methods, calculated EF of some secondary products, introduced weighted factor to calculate yield factors and adjusted biocapacity by an appropriate amount. Meanwhile, we investigated the resource consumption of Liaoning Province in 2006 to assess EF. Its results showed that Liaoning Province overused its natural capital and was in an unsustainable state. We concluded that two specific problems that had arisen in EF assessment and gave some suggestions for Liaoning Province to improve its unsustainable state.     

Detailed Ecological Footprint Accounting of Liaoning in 2006

Abstract

Ecological footprint (EF) has received considerable attention as a useful indicator in the context of sustainable development. So far, EF has been used in numerous studies by academies, organizations and government authorities. However, the results of these studies failed to be comparable directly with each other due to imprecise data sets, unmodified accounting methods of pasture and fossil energy, ignored secondary products, undefined process of calculating yield factors and improper biocapacity for biodiversity. In this paper, we elaborated on EF estimating methods from six categories of consumption in order to overcome the limitations above. We adopted precise data and revised methods, calculated EF of some secondary products, introduced weighted factor to calculate yield factors and adjusted biocapacity by an appropriate amount. Meanwhile, we investigated the resource consumption of Liaoning Province in 2006 to assess EF. Its results showed that Liaoning Province overused its natural capital and was in an unsustainable state. We concluded that two specific problems that had arisen in EF assessment and gave some suggestions for Liaoning Province to improve its unsustainable state.

真空联合堆载预压加固长江漫滩相软基孔压测试分析

结合长江江苏镇江段某码头堆场地基采用真空联合堆载预压法加固处理工程,通过现场钻孔埋设孔隙水压力计,对长江漫滩相软土地基加固过程中孔隙水压力的发展变化过程进行了测试分析。结果表明:真空预压区,加固30d后地基中孔隙水压力变化基本稳定,且土中超静孔隙水压力的消散受该深度排水板中真空荷载的影响十分显著;排水板中真空荷载随深度衰减,衰减速率与排水板周围土层性质密切相关;通过现场测试得到排水板周围为长江漫滩相淤泥质粉质黏土时,真空荷载沿排水板深度衰减速率约为3kPa/m。

风速梯度对海上可燃气云爆燃特性影响的数值模拟

针对海底输气管道和燃气运输船舶发生泄漏形成可燃气云的问题,基于k-ε湍流模型,并利用涡耗散模型,数值模拟6种风速梯度(1～11 m/s)下海上可燃气云的形成和爆燃过程,研究风速梯度对气云爆燃压力和温度特性的具体影响。结果表明:随着风速梯度的增加,稳定气云面积减小,爆燃最大压力降低,下风向低空区域的最高温度略有下降,火焰逐渐远离高空区域,直至完全停留在低空区域;在低空区域,风速梯度为1 m/s时无法形成大面积气云和持续高温,为3～11 m/s 时将形成长时间、大范围的高温区。

目前国内外针对水利设施遭受冰冻灾害的研究还很不活跃,获得的成果还不系统。本文系统分析总结2008年我国南方遭受罕见雪灾导致水利设施的损害情况,以及这些水利设施在极端冰灾影响下的破坏形式,进而提出了一系列有关南方水利设施遭遇极端雪灾的对策,以适应将来积极防灾减灾的需要。     

电除尘器中水雾雾化特性及对除尘性能的影响

湿式电除尘器将水雾除尘与电除尘技术相结合,可以有效地对细颗粒物进行收集,抑制了二次扬尘的发生。通过研究电除尘器喷淋系统的雾化特性,以及不同供水压力对水雾荷电的影响,并测得其分级效率。研究结果表明:在供水压力为0.4 MPa时,湿式电除尘器的除尘效率大于99.5%;在喷雾粒径为100μm时,对10μm以下的细颗粒物除尘效率大于92%。通过分析,为湿式除尘器喷淋系统设计提供了依据。
