Based on the two physical properties lake perimeter and area, Baoan Lake and 30 other lakes in the Jianghan plain were studied, applying the shoreline development index (SDI), the box-dimension, the equation for shoreline length-area and it's transform. The shoreline box-dimension (SBD) was applied to each lake, while equation for shoreline perimeter-area (SPA_N) and its transform (SPA_T) treated 31 lakes altogether. We also used Korcak's Law to all the lakes in Hubei Province. The results showed that the a...
