媒介生态学研究的新视野——媒介作为绿色生态的研究

媒介生态学(Media ecology),是指用生态学的观点和方法来探索和揭示人与媒介、社会、自然四者之间的相互关系及其发展变化的本质和规律的科学.生态学的人文转向,是人类学术史上"世界观转化工程"和"第三次真正的革命".媒介生态学是人类处理"人-媒介-社会-自然系统"相互关系的生态智慧的结晶.建立科学的符合中国国情、结合中国实际、告别西方研究范式的绿色媒介生态理论体系,探索和揭示媒介生态发展与变化的本质和规律,以"循环式食物链"代替"单程式食物链",以"绿色生态链"和"蓝色生态链"替代"灰色生态链"和"黑色生态链",以"媒介生态城堡"取代"媒介智能大楼",是中国媒介生态学的使命和责任.自觉遵循媒介生态系统的信息、物质、能量流动规律和整体优化、互动共进、差异多样、平衡和谐、良性循环、适度调控等原则,是媒介作为绿色生态研究的题中之义.媒介不是一种僵死的封闭的物质实体,媒介生态更是一种具有"生命"特征的开放系统.媒介生态学以其原理与方法、历史与现状、观念与规律、传者生态、信息生态、符号生态、受众生态、报刊生态、影视生态、网络生态等为主要研究内容.     

寒区河道不同模式生态护坡抗水流冲刷试验研究

为改善和提高寒区河道护坡的生态功能,设计了5种生态护坡模式并进行现场试验区建设.通过流速为1.0～5.0 m·s-1有压恒定流连续冲刷试验,采集吸水性、水土流失率、糙率、破坏程度等试验监测数据,分析不同护坡模式抵抗水流侵蚀的能力.结果表明,生态护坡抗冲性能由强至弱依次为:环保草毯混种护坡、植生毯混种护坡、原土射干护坡、...

She also is a representative of all those country girls flooded into cities, a symbol and a sacrifice of the urbanization of America in a time countryside was overcome by cities.
