We tested for fourteen trace elements in samples collected from the Ordovician strata in Datun coal field. The vertical concentration variation of these trace dements is reported. The relationship of the variation to the water-bearing capacity of the Ordovician strata is discussed. The minimum concentration of eleven （of 14 total） trace elements appears in the lower Majiagou formation. The maximum concentrations mainly appear in the Badou and Jiawang formations： eight maxima are located in Badou and four more are in Jiawang. The study of karst development and the water-bearing capacity of Ordovician strata shows that karst is well developed in the Majiagou formation and there is a consequent high water-bearing capacity in this formation： Badou and Jiawang formations are contrary to this situation. The results illustrate that the minimum concentrations of most trace elements within certain Ordovician formations can be taken as strong evidence for the existence of a well developed karst and a high water-bearing capacity.

The Ordovician karst groundwater in the Qiligou basin is an important water supply source. This groundwater has been seriously contaminated in recent years by Cfl4 from a pesticide plant located in the recharge area. The highest concentration of CCl4 in the groundwater is 3909.2μg/L. Large scale tracer experiments were carried out to study the conveying conduits for Cfl4 in the basin on May 1-6, 2005. Nontoxic, edible glucose was used as a tracer and it was detected by spectrophotometric techniques. Well area of the basin, was employed for injecting the tracer X-61, located near the pesticide plant in the southern recharge Ten wells widely located in the groundwater runoff area were used as observing and sampling wells. The results show that the migration of the pollutants is controlled by the water hydrodynamic field and by the development of karst conduits. The tracer did not enter the up-drainage wells, X-49 and X-47, near the injection point because the water levels at these wells are higher than at the injection point. The adjacent well X-62 is close to the injection site, but the tracer reached the well after eleven hours. Wells X-43, X-59, X-58, YY-1 and X-57, located in the syncline axis runoff area, are respectively 2.5, 3.5, 4.33, 4.38 and 5.44 kilometers from the in- jection site. The time for initial appearance of tracer was 4, 4, 2, 6 and 4 hours, respectively. The maximum runoff velocity （well X-58） is over two kilometers per hour, indicating that the karst conduits are well developed along the syncline basin axis. These conduits are the main conveying conduits for groundwater and Cfl4. Closer wells were not necessarily the first to receive tracer. This shows the inhomogeneity in karst development which causes complex runoff, and pollutant migration, patterns.

To reveal additional effects of aquatic macrophytes on biogeochemical properties of onshore lake phosphorus and to investigate the ecological response of reed communities to this phosphorus,sediments from the Meiliangwan onshore reed area of Lake Taihu were sampled by using a columnar sampler (D=8 cm) on September 18,October 17 and December 3,2003. The samples were compared with those from macrophyte-free areas. The collected samples were dried naturally at room temperature,ground and screened with a 100 mesh sieve. The HClO4-H2SO4 digesting and H2SO4-H2O2 heating digesting methods were used to analyze the total amount of phosphorus (TP) contained in sedi-ments of the reed area and in tissues of reed roots and stems. The result shows: 1) the level of TP,from both the reed area sediment and the reference samples,is highest during the vigorous growing stage and lowest during the slow growing stage. The difference between the two levels is statistically significant (p rhizome > stem. All are smaller in the level of phosphorous than that in rhizosphere sediments (0-2 cm).

Xuzhou City is located in the most northwestern portion of Jiangsu Province, P. R. China. Karst groundwater in the Ordovician and Cambrian Limestone aquifers is the main source of water supply. There are 527 wells in urban areas to exploit the karst groundwater, yielding up to 35 000 m^3 per day. After 1978, urbanization and industrialization of Xuzhou City have continued at a greatly accelerated pace; the population increased from 670 700 （1978） to 1 645 500 （2002）, its GDP from 0.71 × 10^9 $ to 42.7× 10^9 $ and the urban area from 184 km^2 to 1,038 km^2 （built-up city area from 41.3 km^2 to 81.9 km^2）. The volume of karst groundwater withdrawal increased yearly before the operation of a supply plant of surface water in 1992, from 3.85x 10^7 m^3（1978） to 1.34× 10^8 m^3 （1991） and now maintained at 0.1× 10^9 m^3 （2002）. Intensive overexploitation of karst groundwater has caused a continuous descending of the piezometric level and the area of the depression cone increases year after year. These changes have increased the vulnerability of the karst groundwater system and have induced environmental problems such as depletion of water resources, water quality deterioration, groundwater contamination and karst collapse. The largest buried depth of karst groundwater is up to 100 m in the dry season in some areas, while 66 exhausted wells have been abandoned. A change in the thickness of the unsaturated zone due to the drawdown of the piezometric level has caused a change of the chemical environment which has an impact on the physical state and major chemical compositions in groundwater. The contents of Ca^2＋, Mg^2＋, NO3^-, SO4^2- and C1^- in karst groundwater has increased significantly, total hardness （CaCO3 content） rises annually in most pumping wells and exceeds the Standard of Drinking Water of P.R. China. Point source pollution and belt-like pollution along the rivers has caused water quality deterioration. The sudden loss of buoyant support due to rapid drawdown of

More effective environmental pollution control and management are needed due to the increasing environ-mental impacts from a range of human activities and the growing public demands for a better living environment. Urban air pollution is a serious environmental issue that poses adverse impacts on the health of people and the environment in most metropolitan areas. In this paper,we propose a geoinformatics augmented framework of environmental modelling and information sharing for supporting effective urban air pollution control and management. This framework is out-lined in terms of its key components and processes including: 1) an integrated,adaptive network of sensors for envi-ronmental monitoring; 2) a set of distributed,interoperable databases for data management; 3) a set of intelligent,robust algorithms and models for environmental modelling; 4) a set of flexible,efficient user interfaces for data access and in-formation sharing; and 5) a reliable,high capacity,high performance computing and communication infrastructure for integrating and supporting other framework components and processes.

以渣油为原料在200mL反应装置上进行加氢脱残炭试验,同时依据渣油残炭的结构组成以及加氢脱残炭的反应历程,对试验结果进行了分析,在此基础上提出渣油加氢脱残炭的三集总反应动力学模型,并与一集总和二集总加氢脱残炭反应动力学模型进行比较。结果表明,一集总动力学模型不能用来描述渣油加氢脱残炭过程,从二、三集总动力学模型的预测数据与试验值误差来分析,将沥青质与胶质做为一个集总或渣油原料的沥青质含量较少时所建立的动力学模型,两者误差精度相当。用三集总的一级反应动力学模型预测渣油加氢脱残炭过程时,与试验值相比,加氢脱残炭转化率的平均绝对误差为0 0056,加氢渣油残炭值的平均相对误差为1 01%。

采用现场采样及室内高效液相色谱分析测试的方法,探讨了微山湖表层沉积物中多环芳烃(PAHs)的分布,并进行了风险评价。结果表明,微山湖表层沉积物中16种优控PAHs的总量范围在324.93～1576.65ng.g-(1干重)之间,平均值为699.01ng.g-1,属中等污染水平,沉积物中的多环芳烃主要来源于煤炭、木材及石油的不完全燃烧。利用沉积物质量基准法(SQGs)、沉积物质量标准法分别对微山湖沉积物中多环芳烃的风险评价表明,严重的多环芳烃生态风险在微山湖沉积物中不存在,负面生物毒性效应则会偶尔发生,风险主要来源于低环的多环芳烃,以芴(Flu)和苊(Ace)为主。
