农村环境连片整治工作自2010年开展以来,连云港市取得了显著的成效,但对农村环境连片整治工作的监控工作仍停留在《全国农村环境监测工作指导意见》(环办[2009]150号)和《江苏省农村地表水环境质量监测实施方案》(苏环然[2007]25号)的要求上,即对连片整治示范区内的农村地表水环境、乡镇和村庄生活污水处理设施进行例行监测,对连片整治示范工程进行验收监测和例行监测工作的层面上。为了加强农村环境连片整治工作的监控,保护农村生态环境,从农村环境连片整治系统架构入手,深入细致地研究了基于WEBGIS的数字监控系统,提出系统所要达到的功能要求。 相似文献

Total suspended particle samples and gas phase samples were collected at three representative sampling sites in the southeastern suburb of Beijing from March 2005 to January 2006. The samples were analyzed for 16 US EPA priority PAHs using GC/MS. Concentrations of Sigma PAHs in particle and gas phases were 0.21-1.18 x 10(3) ng m(-3) and 9.5 x 10(2) ng-1.03 x 10(5) ng m(-3), respectively. PAH concentrations displayed seasonal variation in the order of winter>spring>autumn>summer for particle phase, and winter>autumn>summer>spring for gas phase. Partial correlation analysis indicates that PAH concentrations in particle phase are negatively correlated with temperature and positively correlated with air pollution index of SO(2). No significant correlation is observed between gas phase PAHs and the auxiliary parameters. Sources of PAH are identified through principal component analysis, and source contributions are estimated through multiple linear regression. Major sources of atmospheric PAHs in the study area include coal combustion, coke industry, vehicular emission and natural gas combustion. 相似文献
