城市生态系统研究中遥感技术的应用

Application of remote ensing in urban ecosystem research

本文提出并论证了城市生态系统研究与遥感的总体方案及主要研究方向和研究方法。可以认为,用遥感技术作为获取数据的手段,用动态大系统理论分析数据,并借助于专家系统和地理信息系统处理和管理数据,可以解决城市生态系统研究中全方位信息的收集和巨大信息量的处理两大难题;通过引入中间变量把非空间直接可测变量表述为空间直接可测量的函数,从而在专家系统和地理信息系统的支持下扩大遥感技术的应用领域。

In this paper, the integral programme of urban ecosystem research and remote sensing application, and its main research fields and methodology are put forward and discussed. The authors hold that it is possible to solve two difficult problems of collecting multidimensional data and handling a mass of informations by using remote sensing as a means gathering data, analysing data with the theory of large scale dynamic system, and handling and managing data in terms of expert system and geographic information system(GIS). The unmeasurable variables from space sensor are expressed as a function of measurable ones with the intermediate variables. The research field of remote sensing application is expanded with the aid of expert system and GIS.
