1Leaf morphology correlates with water and light availability:What consequences for simple and compound leaves?显示文摘叶子是对在进化的过程的环境变化敏感的机关并且可以作为对不能生活的应力的回答展出 phenotypic 粘性。然而,叶的肯定在不同环境的词法粘性和它的规定仍然是不清楚的。我们执行了一个模仿的实验在水和轻可获得性的不同坡度学习叶形态学的变化。就叶子和脉络的不同类型而言,当学习反对,我们选择了 Quercus acutissima 的羽状静脉的简单叶子和 Robinia 假相思树的复合叶子。我们调查了的词法参数包括能容易在这个领域里被测量的叶尺寸,形状和脉络模式。重要变化由于环境或异速生长的效果发生在许多参数。为叶有广泛地一致的趋势沿着坡度的词法变化。叶尺寸与资源的短供应变得更小。薄板区域的叶延伸和部分改变了提高资源获得和保存。在在支持和功能的结构的投资之间的交易优化了主要、次要的静脉的脉络模式。传单部分起了象叶牙齿那样的一个作用因为他们是复合的叶的不仅单个单位,而且部分。我们差不多建议那在词法变化的一样的趋势可以是重要解释让共存的种类适应类似的产地并且形成壁龛区别。Fei Xu Weihua Guo Weihong Xu Yinghua Wei Renqing Wang 2009Progress in Natural Science:Materials International2009,19,12:22

4Characterization of contamination, source and degradation of petroleum between upland and paddy fields based on geochemical characteristics and phospholipid fatty acids显示文摘To evaluate contamination caused by petroleum, surface soil samples were collected from both upland and paddy fields along the irrigation canals in the Hunpu wastewater irrigation region in northeast China. N-alkanes, terpanes, steranes, and phospholipid fatty acids (PLFA) in the surface soil samples were analyzed. The aliphatic hydrocarbon concentration was highest in the samples obtained from the upland field near an operational oil well; it was lowest at I-3P where wastewater irrigation promoted the downward movement of hydrocarbons. The Hunpu region was found contaminated by heavy petroleum from oxic lacustrine fresh water or marine deltaic source rocks. Geochemical parameters also indicated significantly heavier contamination and degradation in the upland fields compared with the paddy fields. Principal component analysis based on PLFA showed various microbial communities between petroleum contaminated upland and paddy fields. Gram-negative bacteria indicated by 15:0, 3OH 12:0, and 16:1(9) were significantly higher in the paddy fields, whereas Gram-positive bacteria indicated by i16:0 and 18:1(9)c were significantly higher in the upland fields (p < 0.05). These PLFAs were related to petroleum contamination. Poly-unsaturated PLFA (18:2ω6, 9; indicative of hydrocarbon- degrading bacteria and fungi) was also significantly elevated in the upland fields. This paper recommends more sensitive indicators of contamination and degradation of petroleum in soil. The results also provide guidelines on soil pollution control and remediation in the Hunpu region and other similar regions.Juan Zhang Renqing Wang Xiaoming Du Fasheng Li Jiulan Dai 2012Journal of Environmental Sciences2012,24,11:3
5THE THEORETICAL STUDY OF ADSORPTION OF METAL IONS ON CHITOSAN显示文摘The interactions between metal ions such as Zn2+, Pb2+, Mn2+, Hg2+, Cd2+, Ni2+ and chitosan have been investigated using the model cluster model method and density functional method. Full optimization and frequency analysis of all cluster models have been performed employing B3LYP hybrid method at 3-21G basis set level except metal ions which were invoked to use effective core potential (ECP) method. The energy changes, and the main structural parameters have been obtained during the theoretical study of the adsorption of metal ions on the chitosan. The calculations showed that the coordination modes of metal ions with chitosan models were different, the geometries of Mn2+, Zn2+, Cd2+, Hg2+, Pb2+ ions coordinated with two nitrogen atoms and two oxygen atoms were distorted tetrahedral, while the square planar structure of Ni2+ coordinated two nitrogen atoms and two oxygen atoms was observed. The heat of reaction between six metal ions and chitosan models showed the order: Mn2+ >Ni2+ >Zn2+ >Pb2+ >Hg2+ >Cd2+, this suggested that the coordination strength of Mn2+ >Ni2+ >Zn2+ >Pb2+ >Hg2+ >Cd2+.LU Renqing ZHANG Hongyu QIU Guangmin LIU Chenguang 2005Chinese Journal of Reactive Polymers2005,14,1:3
6Eco-compensation of Wetlands in Yellow River Delta of Shandong Province,China显示文摘Wetlands play an important ecological role and provide many functions for people,yet wetlands are cur-rently decreasing and deteriorating.The ability to calculate an economic value for the loss of wetlands is becoming in-creasingly important for policy makers.In this study,remote sensing,field investigations,department visits,and other methods were used to survey wetland types,assess wetland area changes,and calculate wetland economic value.Mar-ket value loss and ecological function value loss,caused by reduction of wetland area and environmental pollution were calculated using commonly accepted methods of market valuation,ecological valuation,environmental protection investment cost analysis,and outcome parameters.According to market value loss and ecological function value loss,preliminarily fund allocation for wetland and ecological compensation was calculated.This will provide an important reference for future Yellow River Delta eco-compensation studies.HAN Mei CUI Jinlong HAO Zhen WANG Yi WANG Renqing 2012Chinese Geographical Science2012,22,1:3
