中国对流层二氧化硫光化学氧化过程的数值研究

利用一个三维非静力区域大气化学输送模式与中尺度气象模式MM5相连接构成一个数值模拟系统，模拟了中国地区对流层臭氧与其前体物的分布以及二氧化硫转化为硫酸盐的过程，模式扬地面源排放、大气输送和扩散、干沉积、气相化学反应和云雨过程。结果表明：日间，O3浓度主要由NOx和NMHC的源排放和光化学反应过程支配，大气辐射是光化学反应强弱的决定因子，其强度可使SO2、O3和SO4^2-的生成浓度呈现不同的日变化和季节变化，结果表明高浓度的O3对二氧化硫转化为硫酸盐的化学过程有很大的促进作用，然而，这种作用受NMHC浓度的影响很大，较高浓度的NMHC使O3浓度上升，但同时增加了对OH等自由基的消耗，使SO2的转化率降低。     

城市人居环境的协调发展度研究——以上海市青浦区为例

城市人居环境的可持续发展体系是一个由人口、社会、资源、环境与经济5个子系统构成的开放巨系统。通过提出综合衡量系统“协调性”和“发展水平”的“协调发展度”模型，研究人居环境复合系统内5个子系统之间协调发展度情况。并运用灰色预测理论构建GM（1，N）动态模型，预测未来几年各子系统之间协调发展的状况。

杭州市大气NOx来源及控制对策研究

采用定常高斯模式和Thlong程序建立NOx污染源强与大气NOx浓度间定量响应数值模型,计算了点源、面源和流动源等各类污染源对杭州市区各关心点NOx的平均贡献率,分别约为17%,17%和66%,其中市区机动车尾气贡献率高达50%左右,是首先要控制的污染源.同时提出NOx排放削减方案及实施后大气NOx质量改善状况,为环保管理部门削减NOx污染源提出供决策参考.     

The modern theory of biological evolution: an expanded synthesis

In 1858, two naturalists, Charles Darwin and Alfred Russel Wallace, independently proposed natural selection as the basic mechanism responsible for the origin of new phenotypic variants and, ultimately, new species. A large body of evidence for this hypothesis was published in Darwins Origin of Species one year later, the appearance of which provoked other leading scientists like August Weismann to adopt and amplify Darwins perspective. Weismanns neo-Darwinian theory of evolution was further elaborated, most notably in a series of books by Theodosius Dobzhansky, Ernst Mayr, Julian Huxley and others. In this article we first summarize the history of life on Earth and provide recent evidence demonstrating that Darwins dilemma (the apparent missing Precambrian record of life) has been resolved. Next, the historical development and structure of the modern synthesis is described within the context of the following topics: paleobiology and rates of evolution, mass extinctions and species selection, macroevolution and punctuated equilibrium, sexual reproduction and recombination, sexual selection and altruism, endosymbiosis and eukaryotic cell evolution, evolutionary developmental biology, phenotypic plasticity, epigenetic inheritance and molecular evolution, experimental bacterial evolution, and computer simulations (in silico evolution of digital organisms). In addition, we discuss the expansion of the modern synthesis, embracing all branches of scientific disciplines. It is concluded that the basic tenets of the synthetic theory have survived, but in modified form. These sub-theories require continued elaboration, particularly in light of molecular biology, to answer open-ended questions concerning the mechanisms of evolution in all five kingdoms of life.Dedicated to Prof. Dr. Dr. hc mult. Ernst Mayr on the occasion of his 100th birthdayThis revised version was published online in March 2004, with corrections to the caption of Figure 6.     

美国《濒危物种法》介评

一般而言,对濒危物种实施法律保护是世界各国生物多样性保护法律的核心.从世界范围看,美国的濒危物种保护法律制度是极有特色和卓有成效的,其立法规定和司法实践较为完善和成熟.对其进行研究对我国的濒危物种保护立法有较大的借鉴意义.鉴于此,本文对美国濒危物种保护制度的核心--联邦《濒危物种法》（the Endange red Species Act）的主要内容进行研究,以期为我国的物种保护法制建设服务.
