Abstract

Urban water network landscape and hydrological stability are directly related to the healthy development of urban landscape patterns and ecosystems. In this paper, major rivers within the fourth Ring road of Shenyang City are selected as the research object. Based on the high-resolution remote sensing image data of Landsat8 in 2013 and Sentinel-2 in 2021 and the elevation data of DEM in 2021, the landscape and hydrological changes of the water network in Shenyang City are analyzed with the technical support of geographic information system (GIS). The results show : the landscape structure of the Shenyang urban water network is not reasonable, and the water network has low linear connection characteristics and ring connection characteristics. The actual hydrological data of Shenyang changed greatly compared with the hydrological extraction results of DEM: a large number of natural river channels in the lower reaches of Hunhe River were artificially reconstructed, Puhe River received natural reconstruction many times, and the number of artificial ditches in Tiexi District was quite large. Based on the above analysis, combined with the current situation of the Shenyang water network, this paper puts forward reasonable optimization suggestions and corresponding protection and management remedies, to provide guarantee for the sustainable development of Shenyang city, in order provide reference for the planning and construction of water network in other cities.
