基于STRM-3数据的阜康市土地利用垂直分异研究

Study on Height Differentiation of Land Use of Fukang City Based on SRTM-3 Data

土地利用的垂直分异规律是土地利用空间分异研究的一个重要部分。本文采用SRTM-3数据,在对SRTM-3数据空值区域填补的基础上结合阜康市2004年7月LandsatETM+遥感影像,利用ArcGIS空间分析功能,以高程差50 m为单位对阜康市土地利用结构、土地利用程度进行垂直分异的定量研究,得到各高程带的土地利用数据和分析结论。

land use vertical differentiation is an important part of land use spatial differentiation research. This paper used SRTM -3 data to extractbd terrain information. Based on the viod region filled of SRTM -3 data, with the Landsa- tETM Remote Sense images of Fukang in July 2004, and used of ArcGIS spatial analysis functions, quantitative height dif- ferentiation of land use degree and land use composition of FuKang were analyzed at each 50m height zone. After the each height zone analysis of the land use data which derived from SRTM - 3 data and land use classification map, and acquired some results.
