Cumulative effect of highway networks on ecological functions of wetlands in the Longitudinal Range-Gorge region
公路网对湿地生态功能的累积效应研究——以云南纵向岭谷区为例

The cumulative effect of highway networks on the ecological functions of wetlands in the Longitudinal Range-Gorge Region was studied by using remote sensing interpretation and GIS. Since long-term ecological data was not available, we developed a simple method to estimate the accumulated ecological effect of highway networks on wetlands. Firstly, we analyzed the changes of wetland areas within the road-effect zone from 1980 to 2005 using GIS. Secondly, the changes of the ecological functions of wetlands cau...
