石油化工企业灭火中的环境保护

针对近几年来连续发生的石化企业重大火灾后污染水源的恶性事故,在此从消防部队的角度对消防污水的产生与特点进行了探讨,阐述了灭火战斗中注意的问题以及消防污水紧急处置的措施,对石化企业的防火设计及消防监管提出了一些建议,希望消防工作者在致力于消防事业时,同时树立强烈的环保意识,将保护环境作为消防工作的又一目标,力求避免因火灾引发的突发环境事件造成政治、经济和社会方面的重大影响.     

西部开发环境保护工作的几点思考

本文就西部大开发中的环境保护工作提出十个方面的想法：认为应当明确环境保护是西部大开发的基本目标之一；弄清“家底，搞好区划，心快进入西部大开发的前沿阵地；编制西部大开发的环境保护规划；建立综合决策机制；重视资源型产业结构的污染问题；完善法规制度，强化环境管理；加强城镇环境建设与管理；研究包括农村环境保护、水环境保护、生态补偿机制环境投入等环境保护政策；重视环境保护宣传教育；加强基层组织建设和能力建设     

"北大仓"将变成第2个黄土高原?

因土质肥沃盛产粮食而闻名世界的“北大仓”,如今正因大量水土流失变得沟壑纵横,黑龙江这一“全国最大粮仓”的生产能力正在受到来自土壤恶化的威胁。专家呼吁,如不从根本上改变现状,“北大仓”在数十年后很可能会变成第二个黄土高原。     

A regional environmental management information system for Chinese EPA—the system analysis and design

REMIS is one of key research projects sponsored by the central government. It is recommended to regional EPAs as a main tool of the environmental management. REMIS simulates the functions of the regional EPAs and aimed to improve their management level. The national environmental management information system will base on REMIS.Functional analysis is the kernel of the REMIS system analysis. Data and data flow analysis are used to support the functional analysis.Investigations on the functions of the local EPAs of eight provinces and 12 cities have been taken. The functions were carefully sorted. Modular design method was used in system analysis and system design.The system analysis included functional analysis, data analysis and data flow analysis. The system design is based on the system analysis. HIPO diagram of each modular, data base structure, menu design, selection of hardware and software environment were the main items of the system design.     

干旱与半干旱地区土地生产潜力的测定──以新疆阜康县为例

本文探讨了一个通过土壤有效水分含量来确定土地等级和土地生产力的方法。这个方法采用倍增参量形式来确定土壤有效水分。其变量包括潜水位、土层厚度、土壤质地、坡度和盐分。此项研究证明用这种方法获得的土地初级生产力与实测值比较一致。因此，我们可以在类似环境下用这种方法估测土地生产潜力。

Biogenic VOCs emission inventory development of temperate grassland vegetation in Xilin River basin, Inner Mongolia, China

Given the key role of biogenic volatile organic compounds(VOCs) to tropospheric chemistry and regional air quality, it is important to generate accurateVOCs emission inventories. However, only a less fraction of plant species, in temperate grassland of Inner Mongolia, has been characterized by quantitative measurements. A taxonomic methodology, which assigns VOCs measurements to unmeasured species, is an applicable and inexpensive alternation for extensive VOCs emission survey, although data are needed for additional plant families and genera to further validate the taxonomic approach in grassland vegetation. In this experiment, VOCs emission rates of 178 plant species were measured with a portable photoionization detector( PID). The results showed the most of genera and some families have consistent feature of their VOCs emission, especially for isoprene, and provide the basic premise of taxonomic methodology to develop VOCs emission inventories for temperate grassland. Then, the taxonomic methodology was introduced into assigning emission rate to other 96 species, which no measured emission rates available here. A systematical emission inventory of temperate grassland vegetation in Inner Mongolia was provided and further evidence that taxonomy relationship can serve as a useful guide for generalizing the emissions behavior of many, but not all, plant families and genera to grassland vegetation.
