三峡工程与长江中游沿江产业带建设

讨论了长江中游沿江产业带发展条件、限制因素和未来发展，指出三峡工程的建设将对长江中游产业的布局和经济发展带来深刻的变化；防洪作用促进中游两岸大型工业项目的兴建，调整现有沿江城镇的布局，使之结构趋于合理化；电力供应经解能源的紧张状态，改善航运条件，发挥长江黄金水道的综合效益。当然，由于坝下河道冲刷，对现有的码头带来一定的影响，由于冬季水位抬升引起两岸低湖田地下水位上升，加剧两岸土壤潜育化和沼泽化。     

圆形烟道烟尘采样点位置确定之正误

采样点位置的确定是烟尘测试中的一项基础工作。在全国沿用10多年的确定圆形圆形烟道烟尘采样点位置的计算表中的数据,经验算有60％有误;原来以烟道中心为基准的计算公式虽然正确,但实用性差。为了进一步完善烟气测试理论,提高监测质量,提出以烟道内壁为基准的新计算公式。运用新、旧2种计算公式得到一致的计算结果—新计算表,进一步证实了原计算表中的错误。     

平原农区村民居住空间特征与迁居意愿——以江苏省淮安市为例

选择地处苏北平原农区的淮安市所有15510个自然村和872414户农户全样本入户调查数据为分析对象,采用占比统计法和GIS空间分析,对村民居住空间特征与迁居意愿进行研究。主要结论如下：（1）在村落层面,平均规模小,单村独户多且村落分散,多数自然村远离镇区,近一半自然村位居“九靠近一滞洪”区域内。该格局是自然地理条件和人文因素综合影响形成的。（2）在住房层面,农村老旧住房比例高,全市40%农户在城乡同时拥有住房,但在城镇拥有住房率与到城区距离呈负相关,而农村住房空关率则呈现相反的空间格局。（3）在迁居意愿方面,54.1%的农户愿意集中居住且多意向实物安置,较低补偿标准和不便务农是不愿迁居的主要原因;移居城镇是货币安置农户的主要去向,留村和入镇集中居住是实物安置农户的主要去向。在迁居意向农户中,近90%选择政府统建方式,近80%愿意有偿退出宅基地和流转承包地。（4）村民居住空间特征和迁居意愿都存在明显的空间差异,两者之间存有内在联系且均受多种因素影响。     

C OD在线分析仪比对中应注意的问题

分析了COD在线分析仪和实验室比对结果人为差异的原因是样品不均匀,在线分析仪取样装置滤过,取样层面和采样方式以及沉淀消除的方法不同造成的.提出应在相同的地点、层面和同一容器取样,用相同沉淀消除方法去除样品中氯离子干扰,保证两方法比对中使用水样的一致均匀,使测试结果正确可信.     

Multi-level screening of a proposed hazardous waste treatment and disposal facility site--a case study

A comprehensive environmental assessment (EA) is a pre-requisite before the site for developing a hazardous waste treatment and disposal facility (HWTDF) is selected. However, the resource limitations, especially for developing countries, often dictatethat the detailed EA be restricted to those sites, which are constraint free and have low hazard potentials. Thus, a preliminary screening exercise for assessing the suitability ofsite for developing the HWTDF needs to be carried out to avoid huge costs involved in detailed EA. While screening a HWTDF site,various factors such as present land use, ecologically sensitiveareas, geology and hydrogeology of the area, the quality and quantity of wastes, engineered safeguards, and the operationalprocedures that need to be adopted, are required to be addressed. In this paper, a multi-level screening criteria employing RemoteSensing, Constraint Mapping, Groundwater Pollution Potential Index (DRASTIC Index), and the Site Ranking was used to assess the suitability of a proposed site for the development of HWTDF.The study helped to identify various constraints at the proposedsite and their significance on the development of the HWTDF.

Using chemical process simulation to design industrial ecosystems

Chemical process simulation (CPS) software has been widely used by chemical (process) engineers to design, test, optimise, and integrate process plants. It is expected that industrial ecologists to bring these same problem-solving benefits to the design and operation of industrial ecosystems can use CPS. This paper provides industrial ecology researchers and practitioners with an introduction to CPS and an overview of chemical engineering design principles. The paper highlights recent research showing that CPS can be used to model industrial ecosystems, and discusses the benefits of using CPS to address some of the technical challenges facing companies participating in an industrial ecosystem. CPS can be used to (i) quantitatively evaluate and compare the potential environmental and financial benefits of material and energy linkages; (ii) solve general design, retrofit, or operational problems; (iii) help to identify complex and often counter-intuitive solutions; and (iv) evaluate what-if scenarios. CPS should be a useful addition to the industrial ecology toolbox.
