New directions for exploring the consequences of proactive behaviors: Introduction to the special issue

This special issue introduces new directions for exploring the consequences of proactive behaviors. The authors summarize the new scopes of consequences, new social contexts, and new methods in this exploration. They also identify several limitations of the existing literature and call for more future research in this stream.     

Observation of atmospheric nitrous acid with DOAS in Beijing, China

Measurements of nitrous acid （HONO） and nitrogen dioxide （NO2） in Beijing City have been performed by means of a developed differential optical absorption spectroscopy （DOAS） system based on photodiode array （PDA）, during the autumn of 2004. HONO and NO2 were simultaneously identified by their characteristic absorption bands in the spectral region between 337 nm and 372 nm with high sensibility and time resolution. The concentrations of HONO exhibit obviously diurnal variation with a nocturnal maximum and a daytime minimum. The highest HONO value up to 11.8 μg/m^3 was observed during the night of 2/3 September. Possible sources of the observed HONO were discussed. Good correlation to NO2 indicates that NO2 is a main source component. The measurement also shows direct emission of HONO is an imnortant source in strongly polluted urban area.     

德兴地区超大型铜、金矿床成矿控制因素及其模拟实验

在深入研究德兴地区超大型铜、金矿成矿地质背景的基础上 ,从构造地球化学方面着重研究德兴地区超大型铜、金矿床成矿的控制因素 ,并进行构造控矿模拟实验。研究结果表明 ,德兴地区超大型铜、金矿床的形成除因其处于特殊的构造位置 ,具有特殊的地质背景及成矿环境外 ,还与多种地质作用、多种控矿因素耦合作用及地质构造长期发展演化使成矿物质多次叠加富集密切相关     

哲学视野中的环境友好型社会探讨

环境友好型社会建设是中国"十一五"发展战略的重要内容之一,这一理念的提出是全面建设小康社会的现实需要.在深入分析其内涵的基础上,运用马克思主义哲学分析人类从敬畏白然、征服自然,再到环境友好的历史过程,并进一步提出如何推进历史性转变,从决策、法规、经济模式、区域格局、消费方式等方面全面建设环境友好型社会.     

湖泊水体中硫酸盐增高的环境效应研究

通过对高原３个硫酸盐浓度差异的湖泊沉积物水界面硫的形态分布、扩散通量和碎屑有机硫通量等估算，揭示了湖泊水体硫酸盐增加以后的环境效应和自然反馈机制．研究认为：水体向沉积物内部扩散和界面硫酸盐还原作用是高硫酸盐浓度水体硫酸盐的主要清除作用，随硫酸盐浓度的增加，它在水体清除硫酸盐作用的贡献逐渐增大，而低硫酸盐含量湖泊水体生物同化吸收作用是水体硫酸盐的主要清除机制，它在硫酸盐浓度不同的水体没有差异．     

定量风险评价标准探讨

围绕定量评价标准对风险的度量和制定风险评价标准的基本原则等方面的进展和存在的问题进行了初步的探讨，分析归纳了国处有着的个人风险和社会风险标准，提出具有重大危害性的工业设施对员工或公众造成的风险，不应显著高于人们在日常生活中接触到其他风险；每年１０＾－６的死亡风险是可以忽略不计的个人风险水平等观点。     

Analysis on sensitivit and landscape ecological spatial structure of site resources

This article establishes a set of indicators and standards for landscape ecological sensitivity analysis of site resources by using the theories and approaches of landscape ecology.It uses landscape diversity index(H),evenness(E),natural degree(N),contrast degree(C) to study spatial structure and landscape heterogeneity of site resources and thus provides a qualitative-quantitative evaluation method for land planning and management of small ,medium scale areas.The analysis of Yantian District,Shenzhen of China showed that Wutong Mountain belonged to high lanscape ecological sensitivity area,Sanzhoutian Reservoir and Shangping Reservoir were medium landscape sensitivity area and high ecological sensitivity area;Dameisha and Xiaomeisha belonged to medium sensitivity area caused by the decline of natural ecological areas.Shatoujiao,Yantian Pier belonged to low sensitivity area but urban landscape ecological development had reshaped and influenced their landscape ecological roles in a great extent.Suggestions on planning,protection goals an development intensity of each site or district were raised.     

中水回用工程投建与运行实践

沈阳理工大学学生城中水设施的建设，不仅提高了水资源的重复利用率，创造良好的环境效益和经济效益，同时也为中水回用工作的推广实施积累了经验。尤其是采用比较简单的污水处理工艺达到中水回用的标准，其中最主要的部分是沉淀和生物接触氧化以及最后的过滤和消毒，这样的工艺比较适合中等规模的投资，从回用水的经济效益上看这样的中水回用系统还是比较适合推广。     

论矿山环境岩土工程

矿山环境岩土（地质）工程问题是我国环境治理的一个重点和热点问题。本文通过对矿山开发、开采过程中可能出现的几种环境岩土工程问题的分析,提出了几种对矿山环境岩土工程问题进行研究的方法和途径。得出了建立典型的具有代表性的“理论基地”、充分利用现有的新理论新技术和系统论的思维方法是解决矿山环境岩土工程问题的重要方法的结论。
