气候变化对秦皇岛地区降水量影响分析

以秦皇岛市为例,研究了气候变暖对地表降水量的影响.通过对51年来秦皇岛市气候、降水材料的分析得出结论:秦皇岛市近年来明显变暖,年平均气温上升约2℃,同时气候变干,降水量减少18.3%;气候变化会引起水循环的变化及水资源在时空上的重新分布以及水资源总量的改变,对流域内的水资源量影响十分显著.     

China, the United States and technology cooperation on climate control

The U.S. and China are the world's largest and second largest CO₂ emitters, respectively, and to what extent the U.S. and China get involved in combating global climate change is extremely important both for lowering compliance costs of climate mitigation and adaptation and for moving international climate negotiations forward. While it is unavoidable that China will take on commitments at some specific point of time in the future, this paper has argued that the proposal for joint accession by the U.S. and China is not a way forward. For various reasons, such a proposal is in the U.S. interest, but is not in the interest of China. Given the U.S. political reality and institutional settings on the one hand and China's over-riding concern about economic growth and poverty reduction on the other, the two countries are unlikely to take on emissions caps under an international regime, at least for the time being. Therefore, we need to explore the area where cooperation between the two countries to address climate change seems best. The research, development and deployment of clean technology is the area that is in the best interests of the two countries. The U.S. has adopted a technology-oriented approach to climate issues, and has launched the four multilateral initiatives on technology cooperation and the Asia Pacific Partnership for Clean Development and Climate (APP). China has participated in all these U.S.-led initiatives, and is a partner to the APP. Strengthened technology cooperation between the two countries through these initiatives and the APP has led some tangible benefits. However, it should be pointed out that while technology is a critical ingredient in a climate policy package, efforts such as the APP can only be part of the solution. They alone cannot ensure that best available technologies are always deployed in the marketplace, and that new technologies will roll out at the pace and on the scale that we need. In order to have such technology-oriented approach to play a full role, we do need a coordinated policy framework agreed via the Kyoto Protocol or a follow-up regime or the parent United Nations Framework Convention.

Simulation of Combined Best Management Practices and Low Impact Development for Sustainable Stormwater Management1

Damodaram, Chandana, Marcio H. Giacomoni, C. Prakash Khedun, Hillary Holmes, Andrea Ryan, William Saour, and Emily M. Zechman, 2010. Simulation of Combined Best Management Practices and Low Impact Development for Sustainable Stormwater Management. Journal of the American Water Resources Association (JAWRA) 1-12. DOI: 10.1111/j.1752-1688.2010.00462.x Abstract: Urbanization causes increased stormwater runoff volumes, leading to erosion, flooding, and the degradation of instream ecosystem health. Although Best Management Practices (BMPs) are used widely as a means for controlling flood runoff events, Low Impact Development (LID) options have been proposed as an alternative approach to better mimic the natural flow regime by using decentralized designs to control stormwater runoff at the source, rather than at a centralized location in the watershed. For highly urbanized areas, LID practices such as rainwater harvesting, green roofs, and permeable pavements can be used to retrofit existing infrastructure and reduce runoff volumes and peak flows. This paper describes a modeling approach to incorporate these LID practices in an existing hydrologic model to estimate the effects of LID choices on streamflow. The modeling approach has been applied to a watershed located on the campus of Texas A&M University in College Station, Texas, to predict the stormwater reductions resulting from retrofitting existing infrastructure with LID technologies. Results demonstrate that use of these LID practices yield significant stormwater control for small events and less control for flood events. A combined BMP-LID approach is tested for runoff control for both flood and frequent rainfall events.
