Abstract

How to select and quantitate the corresponding factors is one of the important conten - ts to evaluate the waterfront resources of the Yangtze River.The factors in this study include riverbank stability,water-front depth,water-front breadth and water-behind land width.With the help of GIS,overlapping and grid technique are used to quantitate and analyze the water-front depth,water-front breadth and the water-behind land width.And the paper discusses the process on how to acquire all the above - mentioned parameters by applying the correlative technique in detail.In order to find out and quantitate the factors affecting the bank stability,the fractal theory is applied to compute the fractal dimensions of riverbank and islands of the Yangtze River,and on the basis of the mentioned above,multi-temporal satellite imageries and other factors are used to estimate the local bank stability.The integrative evaluation units are acquired from overlapping each of the mentioned evaluation units.Finally,the integrative evaluation is done on the basis of the evaluation units.
