信息生态理论与方法是在当前信息网络空间日趋复杂的背景下发展起来的。互联网在快速发展、取得巨大经济效益和社会效益的同时,也面临着信息污染、信息冗余、信息安全、信用缺失等一系列问题。互联网的进一步发展,既要重视即时效率和效益,更要关注其发展的协调性和可持续性。运用信息生态理论研究网络信息生态系统的结构、信息运行规律、用户行为模式、信息环境评价、系统进化与整体优化等问题具有独特优势。网络信息生态系统是一个复杂的人工系统,对其构成要素、运行和进化规律等进行研究的最终目的, The theory and method of information ecology have developed under the background of the increasingly complex information network space. Along with the rapid development and great economic and social benefits, the Internet is also facing a series of problems such as information pollution, information redundancy, information security and lack of credit. The further development of the Internet should attach importance to immediate efficiency and effectiveness, and pay more attention to the coordination and sustainability of its development. Using information ecology theory to study the structure of network information ecosystem, information operation rules, user behavior patterns, information environment evaluation, system evolution and overall optimization have unique advantages. Network information ecosystem is a complex artificial system, the ultimate goal of its constituent elements, operation and evolution rules,
