An integrated GIS-based analysis system for water environment influence on the urban system around lake areas

Abstract

An integrated GIS-based analysis system for water environment influence on the urban system around lake areas was developed in this paper. The IGAS consists of the theoretical assumption, the theoretical model and the GIS-based application module. Lake effect hypothesis and urban spatial structure theory are used to put forward the theoretical assumption and the diffusion model by Bass is developed to explain the influence effects that water environment affects urban system around lake areas. Meanwhile, the buffer zone analysis, nonlinear regression, extreme equation and thematic mapping are used to construct the application module, respectively. A case study implementing the system was performed on the urban system around Poyang Lake areas, China, which is under significant water environment influence.
