【摘要】：为获取漓江流域水系的空间分布和水系形态特征,以Google Earth影像为数据源,采用人机交互目视解译法提取了流域内的水系形态特征信息,编制了漓江流域水系分布图。通过对水系的等级、密度、分支比、各级水道长度以及交汇角等特征信息进行统计,定量化地展示了漓江流域水系的形态特征;在此基础上进行水系形态特征的控制因素分析,认为地层与断裂构造是控制漓江流域形态的重要因素,人类活动对漓江流域水系形态的影响正在日渐增强。该研究成果为漓江流域的综合治理提供了科学依据,深化了漓江流域的地貌研究。
[Abstract]:In order to obtain the spatial distribution and the characteristics of the river system in the Lijiang River Basin, Google Earth image was used as the data source to extract the characteristics of the river system by human-computer interactive visual interpretation. The distribution map of Lijiang river drainage system is compiled. The characteristics of Lijiang river system are quantitatively displayed by statistics of the grade, density, branch ratio, length and intersection angle of each level of watercourse. On the basis of the analysis of the controlling factors of the characteristics of the river system, it is considered that the strata and the fault structure are the important factors controlling the shape of the Lijiang River basin. The influence of human activities on the form of water system in Lijiang River basin is increasing day by day, which provides scientific basis for comprehensive management of Lijiang River basin and deepens the geomorphological study of Lijiang River basin.
