A fragment constant QSAR model for evaluating the EC50 values of organic chemicals to Daphnia magna.

The quantitative relationship between the median effective concentration (EC50) of organic chemicals to Daphnia magna and the number of molecular fragments was investigated based on experimental EC50 values for 217 chemicals derived from the literature. A fragment constant model was developed based on a multivariate linear regression between the number of fragments and the logarithmically transformed reciprocal values of EC50. Functional correction factors were introduced into the model. The model was verified using an independent set of randomly selected data. The mean residual of the final model was 0.4 log-units. The robustness of the model was discussed based on the results of three jackknife tests.     

南宁城市大气污染对人体健康的危害及治理对策

南宁市大气属煤烟型污染 ,大气的主要污染物为SO2 、NOx、TSP、降尘 ,虽然随着环境管理和污染治理工作的加强 ,污染物浓度逐年下降 ,但是工业区大气污染仍然较重。污染物流行病学调查显示 :工业区癌症和呼吸系统疾病死亡率均高于全市平均水平 2倍左右 ,城区又高于郊区 2倍 ,大气污染综合指数与呼吸内科门诊就诊人数呈正相关。用邓聚龙的灰色系统理论分析得知污染物对癌症和呼吸系统疾病死亡率有关联 ,关联度从大到小排序为 :TSP >降尘 >SO2 >NOx ,最后提出了大气污染治理的对策。     

生态社区综合评价指标体系的初步探讨

生态社区的出现和发展一直广受关注，建立生态社区综合评价指标体系对于生态社区的实践和发展具有重要的意义。本文通过对社区可持续发展理论，生态平衡理论以及生态社区本身系统特点的探讨，尝试建立一个综合评价指标体系，同时对评价指标体系应体现的功能，以及评价指标体系构建的原则做了初步探讨。

对低影响开发与海绵城市的再认识

海绵城市建设是在继承我国古代先贤智慧和参考国外经验,系统总结我国雨洪管理领域长期研究和实践经验的基础上,结合我国城市水系统实际问题提出的城市发展方式,其核心是构建基于绿灰结合的现代城市雨洪控制系统,通过"渗、滞、蓄、净、用、排"综合措施,实现"治涝"与"治黑"等多重目标。低影响开发是海绵城市建设的重要指导思想,也是海绵城市核心技术体系的重要组成部分。正确认识低影响开发与海绵城市的内涵与联系,对于进一步在全国范围内落实低影响开发建设模式,科学推进海绵城市建设具有重要意义。
