Furthermore, based on Two-term local quadrat variance algorithm, a scale decomposing method is pointed out. This thesis also evaluates the question that whether we can apply scale decomposing results into gully ordering results for getting gully ordering system keeping the same scale characteristics results.The primary works and contributions of this thesis are summarized as follows:1. Three term local strip lacuanrity algorithm (3TLSL)This thesis shows that the gliding algorithm of Lacunarity has several shortcomings, such as it can only focus on the current analysis window, and is easily influenced by some local irregular values.

更多。本文进行的主要研究工作如下：1、流域沟谷网络多尺度分析模式与算法研究首先，为解决空隙度的滑动框算法只考虑当前窗口、易受局部异常值影响的缺陷，本文提出了顾及邻域空间关系的3阶局部条形窗口空隙度(Three-term Local Strip Lacuanrity，3TLSL)算法，并以模拟沟谷网络为例，对比分析了3TLSL算法与滑动框算法的结果，研究结果显示，3TLSL算法在分析结果的精确性、可靠性、有效性等方面均有明显的提高。
