突发性环境污染事故应急监测的措施分析

突发性环境污染事故会对环境造成较大的伤害,如果不能及时采取措施,就会使污染进一步扩大,不仅带来经济的损失,而且会破坏到生态的平衡。因此,要建立起突发环境污染事故的应急监测,这样才能尽可能的减少突发性环境污染事件的影响。基于此,本文从突发性环境污染事故的特征入手,首先分析其应急监测的意义,然后探究具体的措施,希望可以借此给突发性环境污染应急监测的相关研究提供一定的参考意见。

How developing countries can engage in GHG reduction: a case study for China

It has been clearly recognized that future global climate change will limit the possibilities for sustainable development in China. To minimize these negative effects, as a practical strategy, we suggest that the Chinese government engage in international cooperation as a key contributor in the prevention of global warming. This suggestion results from numerical estimations of China’s greenhouse gas (GHG) emission trends accompanied with economic growth up to 2100. The results show that China’s gross domestic product (GDP), measured in terms of purchasing power parity (PPP), may overtake the sum of the GDPs of the United States and Canada in 2020. It is predicted that GDP per capita may reach US$20,000 and $80,000 in 2050 and 2100, respectively; meanwhile, CO₂ emissions in China will increase from 6.6 billion tons (in carbon equivalent units) in 1990 to 54.6 billion tons in 2100. This means that the global peak concentration of GHG cannot be practically reduced without significant contributions from China. For international cooperation in mitigating global climate change, we introduce a new option, “per-capita emission restricted by assigned amount,” as an accounting rule for GHG reduction. This baseline classifies global CO₂ reduction actions into three categories: compulsory reduction, self-imposed reduction, and voluntary reduction. We suggest that China contribute to world CO₂ reduction according to the following timetable: voluntary reduction until 2012, self-imposed reduction until 2020, and compulsory reduction from 2020. The simulation results also indicate that China can benefit from this strategy in terms of improvements in its domestic economy and environment, for instance, by reducing fossil fuel consumption and the emission of pollutants.

浑河沈阳段“十一五”水环境建设技术对策的探讨

浑河是沈阳市水系的水脉,也是沈阳市建设与发展的命脉。“十一五”期间,沈阳市对浑河实施的大规模综合整治,实现了浑河水环境由“厌氧型严重污染水体”向“好氧型轻度污染水体”的转变。对于“十一五”浑河水环境的建设,则应以水质升级达标和生态环境建设为目标,重在“污染控制与水质改善”“水资源保护与开发利用”和“生态环境保护与建设”三个方面取得新突破和新成果。
