Information ecology is a new research area of modern ecology. Here describes the spatial distribution analysis methods of four sorts of climatic variables, i.e. temperature, precipitation, relative humidity and sunshine fraction in Northeast China. First, digital terrain models was built with large-scale maps and vector data. Then trend surface analysis and interpolation method were used to analyze the spatial distribution of these four kinds of climatic variables at three temporal scale: (1) monthly data; (2) mean monthly data of thirty years, and (3) mean annual data of thirty years. Ecological information system were used for graphics analysis on the spatial distribution of these climatic variables.
信息生态学是现代生态学的一个新的研究领域。这里描述了中国东北地区四种气候变量，即温度、降水、相对湿度和日照率的空间分布分析方法。首先，利用大比例尺地图和矢量数据构建数字地形模型。然后，采用趋势面分析和插值方法，在三个时间尺度上分析这四种气候变量的空间分布：（1）月数据；（2）三十年的月平均数据；（3）三十年的年平均数据。利用生态信息系统对这些气候变量的空间分布进行图形分析。
