APPLICATION OF GIS IN ANALYZING ECOSYSTEM'S RELATIVE SENSITIVITY TO ACID DEPOSITION

This paper decribo an application of GIS technology in estimating estem's relive sensitivity to acid despition.East China is selected as the research area.Four variable layers, which are ha rock, soil buffering ability, vegetation type and soil humidity, are used in the process.Five grades are separated in this research.The sensitivity mapping is also discussed in this paper.
