【摘要】:為獲取漓江流域水系的空間分布和水系形態(tài)特征,以Google Earth影像為數(shù)據(jù)源,采用人機(jī)交互目視解譯法提取了流域內(nèi)的水系形態(tài)特征信息,編制了漓江流域水系分布圖。通過對(duì)水系的等級(jí)、密度、分支比、各級(jí)水道長(zhǎng)度以及交匯角等特征信息進(jìn)行統(tǒng)計(jì),定量化地展示了漓江流域水系的形態(tài)特征;在此基礎(chǔ)上進(jìn)行水系形態(tài)特征的控制因素分析,認(rèn)為地層與斷裂構(gòu)造是控制漓江流域形態(tài)的重要因素,人類活動(dòng)對(duì)漓江流域水系形態(tài)的影響正在日漸增強(qiáng)。該研究成果為漓江流域的綜合治理提供了科學(xué)依據(jù),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.
