| 摘 要： | “空间性”是地理空间数据有别于其他数据的显著特征,因此地理空间数据研究过程中必须反映和遵从其地理空间特性。本文将集中于两个领域,即统计分析和遥感图像分析领域,来论述地理空间数据分析中必须加强对空间异质性、空间结构和尺度的探讨。

| Abstract: | "Spatial feature"is the geographical spatial data famous feature different from that of the other data, so in the process of researching geographical spatial data, it must be reflected and conformed to other geographical spatial feature. This paper focused on two fields, namely statistical analysis and remotely sensed imagery analysis, to discuss that in the spatial data analysis the exploration of spatial nonstationarity, spatial structure and scale must be intensified. |

| Keywords: | spatial data spatial nonstationarity spatial structure scale |
