公共场所水源中军团菌的研究进展

军团菌是一种条件致病菌,存活在各种水环境中。当感染的气溶胶被吸入到体内,可能会导致严重的肺炎,称之为军团病。近年来各种公共场所水源中嗜肺军团菌的污染情况逐年增加,对人类的健康造成严重威胁,本文从军团菌的生物学特性、生境环境、流行病学、检测方法等几个方面对军团菌研究进展做以综述。

邯郸市生态水网建设水源优化配置模型研究

面对日益凸显的缺水局面和生态环境恶化,邯郸市政府开发建设了邯郸生态水网工程,通过区域性调水,改善了区域严重缺水的现状。面对多种水源的调水选择,采用经济效益、社会效益和环境效益三大目标函数建立了水源优化配制模型。并对传统“环境效益”函数进行了改进,凸显了“水质质量”指标在选取调水水源中的作用,这一改进对区域水环境修复起到至关重要的作用。

从农村基层自治角度理解自治理论——以G村为例

以统治视角出发的官僚制，在其合理性和合法性上有着先天性的缺陷。而任何一种对官僚制超越的途径——无论是从宪政的角度还是从伦理的角度，都难以回避民主行政的这一道路。尽管在政治学的理论中，民主并不一定是最好的制度设计，但是就目前的现状来看，民主仍然是决策较好的方式。本文试图通过对农村基层民主治理的角度来深入了解自治理论，进而探索出农村基层公共物品的使用和分配方式，并为我国的民主建设提供借鉴。

Urban Water Supply Industry Marketization of China in View of Public Water Service and Water Resource Management

Started with the discussions on the value orientation of urban water supply industry marketization,the article points out that the current urban water supply industry marketization reform is inconsistent with the goal of public water service equalization to some extent.The article also analyzes the problems emerged in urban water supply industry marketization reform and various rea-sons in view of efficiency and fairness.An efficiency and fairness oriented management model is built in this article to illustrate how the government should conciliate interests of various communities involved in the process of marketization reform of the urban water supply industry so as to actualize the coordination of efficiency and fairness.At the end,an assumption on urban water price is put forward to help achieve the public water service equalization.
