Abstract：The conceptual model which could well illustrate the fluctuations of riverine ecosystem is still to
be developed. The hydraulic，water environmental，and biological characteristics of the inshore area of a riv⁃
er are distinctly different from those in main stream. The variations of position and size of the inshore belt
are relatively obvious compared with those of the main stream，thus the fluctuation of the inshore belt can
depict the ecological effects of hydrological process and the variation of the water area better. In this pa⁃
per， the definition of inshore belt was generalized， and a conceptual model illustrating the mapping rela⁃
tion between the size of inshore belt and the variation of water level was presented， which seems applica⁃
ble to different channel types such as straight / slightly sinuous， sinuous and braided type. There are two
size peaks with the inshore belt on the curve depicting the mapping relation. In the viewpoint of riverine
landscape，inshore belt can be regarded as a ribbon-like matrix of water area of a river，with perfect conti⁃
nuity both in time and space span； the main stream belt can be treated as a type of structure emerging
from the inshore belt matrix，when the discharge surpasses a critical value. The upper Yangtze River reach
from the Nanxi Town to the Jiangan Town was employed as an example to examine the conceptual model，
and how to define the inshore belt together with its application in the classification of ecological hydrologic
components was discussed finally.
Keywords：inshore belt；mapping relation between inshore belt size and hydrologic condition；riverine land⁃
scape；matrix；upper reaches of the Yangtze River
