ClO2和碳水化合物水平对中国明对虾存活和生长的影响

研究了盐度为5条件下,ClO2和碳水化合物水平对中国明对虾(Fenneropenaeus chinensis)存活和生长的影响,共两个实验:实验1研究了ClO2(0、1、4、7、10、13、16、19和22 mg/L)对中国明对虾存活的影响,发现随ClO2浓度的升高,对虾存活率呈下降趋势;在24、48、72和96 h,LC50分别为21.04、13.32、10.91和8.26 mg/L,安全浓度为1.60 mg/L.实验2研究了ClO2(0.0、0.2、0.4和0.6 mg/L)和饲料中碳水化合物水平(13.89和41.76%)对中国明对虾存活和生长的影响,发现在两个碳水化合物水平,随ClO2浓度的升高,对虾存活率、特定生长率、摄食量和吸收效率均呈下降趋势,而饲料系数呈上升趋势;在四个ClO2水平,摄食13.89%碳水化合物对虾的特定生长率、摄食量和吸收效率均高于摄食41.76%碳水化合物的对虾,而摄食13.89%碳水化合物对虾的饲料系数低于摄食41.76%碳水化合物的对虾.     

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。

Occurrence and congeners specific of poiychlorinated biphenyls in agricultural soils from Southern Jiangsu, China

A total of 198 agricultural soil samples were collected from Zhangjiagang and Changshu in Southern Jiangsu for analysis of 13 polychlorinated biphenyls (PCBs) in order to assess the levels of pollution, sources, area distribution, and potential risk for the environment. All methods were rigorously tested and an adequate quality control was ensured. Only one site had no PCBs residues, and the highest total PCBs concentration in the surface soils was 32.83 ng/g. The average concentration in all the soil samples was 4.13 ng/g, signaling low-level pollution. Tetra-, penta-, and hexa-chlorinated biphenyls were dominant species in soil samples, accounting for more than 75% ofΣPCBs in the soil samples. PCB118 was the most abundant congener in all the samples. The PCB118 was about 20% ofΣPCBs. The soil organic matter content showed only a weak correlation with the levels of all PCB congeners, in which a better correlation was noted for the more volatile lighter PCB congeners than for the heavier homologues. To a certain extent, the sources and land use seemed to influence the levels of PCBs.

铜陵石炭纪威宁期沉积相及与黄铁矿矿床的关系

铜陵地区石炭纪威宁期存在潮坪相,泻湖相和浅海陆棚相。白云岩有两种,准同生白云岩分布于潮坪,成岩白云岩分布于泻湖内,本区以成岩白云岩为主。白云岩中赋存了层位稳定的黄铁矿矿床,黄铁矿在泻湖相最易富集,成岩作用是黄铁矿矿床形成的一个重要因素。
