中国发展生物质能源的战略措施思考

能源连人类社会赖以生存和发展的重要资源。随着中国经济的持续发展，能源与环境对经济发展的制约作用逐渐得到显现．能源问题与环境问题已经成为国家发展的战略性问题。因此发展生物质能是解决中国能源紧张的重要突破口。发展生物质能的战略措施是建立生物质能源的产业体系。即相对于传统产业体系的第二产业体系。具体战略阶段是：2000—2010年实验探讨阶段（初级阶段）；2020—2030年推广应用阶段（发展阶段）：2030年一2050年优化提出阶段（提高阶段）。生物质能源的发展战略有助于“三农”问题的解决即农村小康社舍的建设；有助于减轻环境压力；有助于维护国家能源安全。     

Human adaptation to climate change: a review of three historical cases and some general perspectives

To study mitigation and adaptation to climate change, social scientists have drawn on different approaches, particularly sociological approaches to the future and comparative history of past societies. These two approaches frame the social and temporal boundaries of decision-making collectivities in different ways. A consideration of the responses to climate variability in three historical cases, the Classic Maya of Mexico and Central America, the Viking settlements in Greenland, and the US Dust Bowl, shows the value of integrating these two approaches.

HEAVY RAINFALL DISTRIBUTIONS BY SEASON IN LOUISIANA: SYNOPTIC INTERPRETATIONS AND QUANTILE ESTIMATES1

ABSTRACT: In most studies, quantile estimates of extreme 24-hour rainfall are given in annual probabilities. The probability of experiencing an excessive storm event, however, differs throughout the year. As a result, this paper explored the differences between heavy rainfall distributions by season in Louisiana. It was concluded by using the Kruskal-Wallis and Mann-Whitney tests that the distribution of heavy rainfall events differs significantly between particular seasons at the sites near the Gulf Coast. Furthermore, seasonal frequency curves varied dramatically at the four sites examined. Mixed distributions within these data were not found to be problematic, but the mechanisms that produced the events were found to change seasonally. Extreme heavy rainfall events in winter and spring were primarily generated by frontal weather systems, while summer and fall events had high proportions of events produced by tropical disturbances and airmass (free-convective) conditions.
