论城市创新的生态思维--推动城市可持续发展的新思维

城市化是人类生产和生活方式转型的必然结果,由于城市建设过程中依照的是传统思维模式,导致各大城市均不同程度存在一定的城市病。因此要加强可持续发展生态思维的观念,以期推动我国城市生态化与可持续城市建设工作的开展。

Immobilization of iodide on copper(I) sulfide minerals

In the goal of finding efficient scavengers for radioiodide in conditions (pH, pE) close to those encountered in deep geological sites, sorption of iodide ions on cuprous sulfide minerals (especially roxbyite, Cu(1.75)S) has been studied. Surface analysis by X-ray photoelectron spectroscopy has shown that commercial cuprous sulfides are covered by an oxidized overlayer (mainly in the form of CuSO(4)). Therefore, a synthetic procedure to get roxbyite (typically by mixing Na(2)S with an aqueous suspension of commercial Cu(2)O) was applied to produce pure samples with clean surfaces. Batch equilibration of cuprous sulfide particles suspended in aqueous solutions containing iodide species has revealed significant consumption of iodide. The sorption mechanism involves the formation of a surface complex via the exchange of surface hydroxyl groups by iodide anions, as highlighted by a transient pH increase during the immobilization process. Other copper and mixed copper-iron sulfides (e.g. CuS, CuFeS(2)), which are stable over wide pH and potential ranges are also likely to accumulate iodide species. Because of the specific interaction between iodide and copper(I) centers on the minerals, high distribution coefficients (>1000 ml/g) were observed.     

The Information Cycle as a Framework for Defining Information Goals for Water-Quality Monitoring

/ The necessity to tailor information becomes increasingly urgent as the information revolution continues to generate ever-increasing flows of data and so-called information. From European experiences, a new approach for monitoring system design is suggested in this paper. In this approach, careful and detailed specification of information needs is a major contributing factor to the effectiveness of information products. To develop better specifications for information products, the process of collecting and transforming data into useful information requires careful thought and guidance. A dialogue between information users on one hand and information producers on the other is essential. This dialogue can be based on the information cycle, describing the continuous process from specifying information needs for water management and a strategy to collect information through data collection and data analysis up to utilization of information by water management. By following the respective steps in the information cycle, the process of information gathering can be completed. The cyclic character provides a quantitative means of connecting monitoring system design and operations with the information expectations and/or products required by management.     

论建立我国林木采伐远期责任法律制度

森林资源在生态系统的保护中有着多方面的功能,保护森林资源对于环境保护、经济发展和科学研究有着重要意义。我国森林资源破坏严重,其中重要原因之一就是有关森林资源保护法律中存在着许多不完善之处。本文指出我国《森林法》关于法律责任规定存在的问题,提出了违法砍伐林木者应当承担远期保护责任的立法建议。

诗歌三首

黄河史源头哭着,一路奔下来,在鲁国境内死于大海。一个三十七岁的汉人,为什么要抱着她一起哭?在大街,在田野,在机械废弃的旧工厂他常常无端端地崩溃掉。他挣破了身体举着一根白花花的骨头在哭。他烧尽了课本,坐在灰里哭。他连后果都没有想过,他连脸上的血和泥都没擦干净。秋日河岸,白云流动,景物颓伤,像一场大病。History of the Yellow Rive白云浮动白云浮动,有最深沉的技艺。梅花亿万次来到人间田野上,我曾见诸鸟远去却从未见她们归来她们鹅黄、淡紫或蘸漆的羽毛她们悲欣交集的眉间诸鸟中,有霸王也有虞姬白云和诸鸟啊我是你们的儿子和父…     

宁波化工区经济发展和环境保护实现"双赢"

2006年11月22日原化工部副部长林殷才考察宁波化工区时曾这样评价:“宁波化工区在开发建设中,高度重视环保工作,充分考虑区域环境容量,基础设施建设超前,做到了经济发展和环境保护“双赢”,已经成为全国为数不多的一流化工园区。”一个化工专家用其挑剔的眼光审视一个化工园区后,也给予了高度肯定。这说明宁波化工区在环境保护方面,规划先导,基础先行,按照科学发展观的要求,构建循环经济产业链的做法已经取得了成效。
