| 1 | 中国太湖1950年以来主要环境的变化和迅速富营养化的开始显示文摘太湖是我国第三大淡水湖,面积2350km2,位于长江三角洲(面积35000km2)的中部,自6000年前太湖形成以来,湖泊经历了几个主要变化。1950年以前,太湖最明显的变化发生在海侵和湖盆大小。海侵是太湖形成的主要原因。太湖形成后,在不同的干燥和湿润时期,湖盆经历了由一系列的小湖或统一湖盆之间的波动。但一般来说,近2000年以来,湖盆的大小在增大。然而1950年以后,为适应人口的增长,许多浅水地带被改造成农田和鱼塘。50年代以来,对湖盆和流域的进一步利用导致湖泊发生了一些变化。在这个阶段太湖的主要变化是:1)对排水流域、湖泊生态和营养状况具有重大影响的堤坝的修筑和湖岸的改造;2)始于1983/1984年湖泊的迅速富营养化。湖泊迅速富营养化的主要原因是由于工业、农业和城市化的迅速增长,导致未经处理的废水排入湖盆。每年这些营养物大量排入,对湖泊的营养状况影响甚重,在低水位时尤其如此。 | William Y.B.Chang(Center for Great Lakes and Aquatic Sciences and School of Natural Resources and Environment,the University of Michigan,Ann Arbor,Michigan 48109,U.S.A.andDivision of International Programs National Science Foundation,Foundation,Arlington, | 1996 | 古生物学报1996，35，2： | 8 |

| 3 | Polyphyly of the fern family Tectariaceae sensu Ching:Insights from cpDNA sequence data显示文摘Tectariaceae are a pantropical fern family of about 20 genera, among which 8 are distributed in China. The morphological distinctiveness of the family is widely recognized, yet relatively little systematic research has been conducted on members of Tectariaceae. Phylogenetic analyses of chloroplast DNA sequence data (rbcL and atpB) from 15 species representing all 8 genera in China were carried out under parsimony criteria and Bayesian inference. The phylogenetic reconstructions indicated that the fern family Tectariaceae as traditionally circumscribed are polyphyletic. Ctenitis, Dryopsis, Lastreopsis clustered with and should be included within the newly-defined Dryopteridaceae, and Pleocnemia is also tentatively assigned to it. A narrowly monophyletic Tectariaceae is identified, which includes Ctenitopsis, Hemigramma, Pteridrys, Quercifilix, and Tectaria. In the single rbcL analysis, Arthropteris clustered with the above-mentioned monophyletic Tectariaceae. Although further investigations are still needed to identify infrafamilial relationships within the monophyletic Tectariaceae and to redefine several problematic genera, we propose a working concept here that better reflects the inferred evolu- tionary history of this group. | LIU HongMei1,2, ZHANG XianChun1, CHEN ZhiDuan1, DONG ShiYong3 & QIU YinLong4 1 State Key Laboratory of Systematic and Evolutionary Botany, Institute of Botany, Chinese Academy of Sciences, Beijing 100093, China 2 Graduate University of Chinese Academy of Sciences, Beijing 100039, China 3 South China Botanical Garden, Chinese Academy of Sciences, Guangzhou 510650, China 4 Department of Ecology and Evolutionary Biology, University of Michigan, Ann Arbor, MI 48109-1048, USA | 2007 | Science China(Life Sciences)2007，50，6： | 5 |

| 9 | Analysis of Changes in Energy Consumption and Demand Trend in China's Agricultural Production显示文摘China's energy consumption for agricultural production has relied on petroleum and coal with relatively low input from power and other types of energy for a long time.Projections indicate that as China's existing development trend leads to substantial growth of energy demand for agricultural production,such a long term irrational energy consumption pattern would unlikely be able to meet the needs of the country's developing agricultural sector.As such,it is recommended that China's agricultural sector should follow the national energy development strategy guideline by gradually increasing the use of wind power,solar energy,biomass and other new energy sources while advancing technological innovations on traditional energy sources.Meanwhile,as the consumption structure of three major energy sources(i.e.petroleum,coal,and power)is optimized,development and application of biomass from agriculture as raw materials for alternative energy should be enhanced.Lastly,the development and application of wind power,solar energy,and hydropower in agricultural production should be increased in areas where appropriate. | ZHU Li-zhi1,LIU Jing1,XU Ran2,XIANG Meng1 1.Institute of Agricultural Economics and Development,Chinese Academy of Agricultural Sciences(CAAS),Beijing 100081,China 2.University of Michigan,Ann Arbor,MI(48104),USA | 2011 | Asian Agricultural Research2011，3，3： | 1 |
