River system changes due to urbanization in lower plain water network region of Taihu Lake

摘要：

　　Based on the remote sensing image information and relative socio-economic data conducted during the period from 1991 to 2006, the characteristic and structural changes of river system of lower plain water network region of Taihu Lake are discussed in this paper. The growth evolution of the river system including the river siltation and landfill as well as the changes in the production mode and lifestyle during the rapid urbanization are thoroughly studied in this area. The results show that the Horton theory still plays an important role to evaluate the river system evaluation and several statistical indicators, just as the density of river network, the complexity of river network, the complexity of river network, the average branching ratio, the average length ratio and dimension of river system etc., can be used to describe the river system development. Significant relations between these indicators and river structure are noticed, indicating that the self-similarity of river development lies in different river grades and the river system becomes simpler because of the human activities in this region.
