摘要:
以南方红壤丘陵区宝洞峪小流域作为实验样区，在地理信息系统技术空间分析和水文分析模块的支持下，采用不同分辨率的DEM为基本信息源，探讨了汇流阈值与汇流网络密度间的定量关系。研究结果表明：汇流阈值与汇流网络密度呈定量统计关系。经过对所得数据的回归分析，得出了汇流阈值与汇流网络密度的定量回归模型，其中系数b呈较明显的空间分异特征并随着DEM精度的变化而变化。还提出了一种基于栅格个数的汇流网络密度计算方法，通过在实际研究中的应用，表明该方法可以有效地应用到汇流网络结构研究中。
Abstract:
The Baodongyu catchment in red soil hilly region of Southern China was selected as the study site. Under the support of spatial analysis and hydrological analysis module of ArcGIS, the research discussed the quantitative relationship between conflux threshold value and densities of conflux network using DEM with different resolving power. The result showed that there is a quantitative relationship between conflux threshold value and densities of conflux network, which can be expressed by a formula. And the parameters b presented on a change trend with the precision of DEM. The research put forward a good approach of computing conflux network density based on raster number, which could be effectively used to determine drainage structure.
