【摘要】 网络社会是以网民为活动主体,以计算机和通信等现代信息技术为基础环境,两方面共同作用所形成的新社会形态。在这个新社会形态中,存在着各种各样的网站、论坛和社区。由于其数量之多,范围之广,所以在运营上他们本身会出现如网站经营效率不好,论坛或社区人气不高等一些现实问题。因此,如何来认识这些问题,分析网络社会群落中表现出来的生态稳定性,也就成为了当前需要研究的重点。本文基于网络社会群落与生物群落在生态稳定性上存在一定的相似性,我们借助于系统科学、数学生态学、社会学等知识,首先将生态学的基本理论引入网络社会,界定了网络社会物种、种群、群落的含义;然后对网络社会群落的类型多样性进行分析,提出运用多样性测度方法来分析网站、论坛及社区内部构成的多样性;系统的分析了网络社会群落复杂结构分布,同时提出运用营养网络结构和符号有向图的方法对网络社会群落的结构进行设计;在对类型与结构进行分析的基础上,建立了分析网络社会群落生态稳定性的动力系统概念模型;然后由一般到具体,进行深入研究,以天涯社区应用分阶段种群结构生态稳定性模型为例进行验证,进行算例求解得出需要的生态稳定性平衡点,并对其结果进行了分析;最后,对本文研究内容进行了总结,同时对进一步研究方向作出了展望。更多还原

【Abstract】 Network society is the main activities of Internet users, and based on environment with the other modern information technology of computer and communication, by the interaction both formed of the new social pattern. In the new social form, there are all kinds of sites, forums and communities. Because of the number and broad scope of them, so, in their own operations on the site will appear some practical problems such as poor operational efficiency, community forums or popularity is not higher. Therefore, how to understand these issues, analysis the ecological stability demonstrated by the network society community, will become the current needs of the focus of the study.Based on that there are certain similarities on the ecological stability between the network society communities and biological communities, we borrow knowledge of system in science, mathematics ecology, sociology. First of all, the basic theory of ecology will be the introduction of the network society, defined the meaning of the network society species, Stocks, communities. Then analysis the diversity of the types of the network society community, and use of methods to measure diversity of sites, forums and community; and analysis the complex structure of network society communities, at the same time put Nutrition network structure and the use of symbols is to design structure of the network society communities; On the basis of the structure and the type of analysis, we establish of a dynamic system concept model which use of analysis the ecological stability of the network society community; And then from the general to Concrete, in-depth study, take Tianya community to verify population structure in stages of the ecological stability model as an example, and that for example the need to balance point of ecological stability, and analysis the results; Finally, the paper Research carried out a summary, and the direction for further research to the future.更多还原
