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.

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.     

兰州市城市生活垃圾处理研究

城市生活垃圾是指在城市日常生活中或者为城市日常生活提供服务的活动中产生的固体废物以及法律、行政规定视为城市生活垃圾的固体废弃物.随着中国城市化进程的加快和人民生活水平的提高,城市生活垃圾也在以每年8%～10%的速度增长,若垃圾问题得不到妥善解决,就会制约兰州市的发展.在对兰州市城市生活垃圾处理现状及存在问题分析的基础上,根据兰州市生活垃圾的特性,提出兰州市城市生活垃圾的处理办法:兰州市城市生活垃圾应当推行分类收集制度,由目前单一的卫生填埋处理走向资源化综合处理.     

黄河口及邻近海域溶解态无机磷、有机磷、总磷的分布研究

于2003年8月下旬对黄河口及邻近海域进行了十船连续同步27h采样调查,分析了调查区域的溶解态无机磷、有机磷、总磷的平面分布、断面分布、时间分布特征.结果表明,在调查区域内,溶解态无机磷浓度很低,而溶解态有机磷浓度较高(占溶解态总磷的85%以上),是溶解态总磷的主要组成部分.各形态磷的平面分布、断面分布均呈现出由河口向邻近海域降低的趋势,溶解态总磷、溶解态有机磷梯度变化较溶解态无机磷更为明显;潮汐对河口浅水区的各形态磷浓度影响较大,对邻近调查海域的影响不明显.
