栅格尺度对星丰流域坡度坡向的影响
he influence of size of grid on Topographic slope and aspect over XingFeng drainage area
坡度和坡向是进行地形特征分析和可视化的基本因子，结合其它因子，坡度和坡向可以在各个领域得到广泛应用。本文以星丰流域为例，基于DEM的基础上，通过改变栅格尺度定性定量的比较不同栅格尺度对坡度坡向的影响，确定一些敏感尺度，进而为以后的实际工作起到一定的指导作用。通过比较得出星丰流域的敏感尺度是125m，在实际中应尽量避免这些尺度。
opographic slope and aspect is the basic factors of analyzing and Visualizing Topographical features. Combined with other factors, slope and aspect can be widely applied in various fields. Take the basin of xingfeng for example, based on DEM, thought changing Grid Scale we analyze the influence that how Grid Scale impact topographic slope and aspect. From that we can identify some sensitive scales and what’s more use them to guide the future actual practice. Though contrasting, Grid Scale of 125m is the sensitive scales, and we should try to avoid these measures
