Urban Rivers: A Landscape Ecological Perspective

Abstract

Urban rivers are important physical elements and important ecological corridors. They not only play important ecological roles but also supply bases of stability, comfort, and sustainability in urban development. Due to the complex interaction between inner and outer elements of urban river landscapes, it is necessary to use the theory of landscape ecology to analyze the pattern, function, context, fragmentation and temporal change of urban river landscapes with appropriate scale. It will support the management and sustainable development of urban rivers. The main purpose of this paper is to analyze the urban river landscapes from landscape ecological perspective. This paper firstly reviews the relevant studies in urban river landscapes, and then it carries out the research on the pattern of river corridors and river networks and the service functions. Next, it probes into the river landscape dynamic change at pattern and function aspects and the scale of relative study. Specially, because urban rivers are widely influenced by human activities, so this paper analyzes the disturbance of urban rivers further. This paper has proposed a basal framework for the research on urban rivers by the use of fundamental topics including pattern, function and dynamic change and so on in landscape ecology. It will play a directive role to understand urban rivers, resolve the water environment problems and to realize the sustainable development of urban river resources.

Konservasi Menara Sleko Menuju Lansekap Kawasan Kota Kuno Semarang

“…Sungai juga berperan dalam memasok sumber daya air dan cara transportasi, meningkatkan keanekaragaman lanskap kota, memperkaya kehidupan warga kota dan berkontribusi pada stabilitas, kenyamanan, dan keberlanjutan dalam pembangunan perkotaan (Baschak & Brown, 1995). Sungai pada kawasan perkotaan terutama pada peran sungai sebagai jalur perdagangan menjadi salah satu daerah yang paling terpengaruh secara intensif dalam interaksi antara manusia dan proses alam (Yue, 2012).…”

Ecological Restoration Effectively Mitigated pCO2 and CO2 Evasions From Severely Polluted Urban Rivers

“…With over 56% of the world population residing in urban areas, urbanized catchment areas are being increasingly threatened by human activities including excessive pollution production and physical modifications (UN‐Habitat, 2022). Urban rivers refer to rivers flowing through urban areas with most or all of the basin surface covered by urban land use and other artificial facilities, encompassing both man‐made and natural channels (Yue, 2012). Most urban rivers experience water quality deterioration, harmful eutrophication, terrestrial infiltration reduction, hydromorphological condition alteration, and relevant carbon biogeochemical cycle changes as a result of intricate watershed human perturbations (Astaraie‐Imani et al., 2012; Williams et al., 2016).…”

The Impacts of Precipitation on Fluorescent Dissolved Organic Matter (FDOM) in an Urban River System

“…With the rapid development of urbanization, their ecosystem service functions have been gradually diversified [2,3]. Currently, the aggregated functions of urban rivers include the supply of water [4], shipping [5], landscape [6], the receipt of wastewater [3], irrigation [7], and micro-climate regulation [8]. Urban rivers also serve as spillways for flood discharge in cities with frequent rainstorms [9][10][11][12].…”
