The Ration RS Research Of Eco-environment Frangibility Based On Multi-source Data

The frangibility of eco-environment is the main research of Global environment change and Climate change. And also one of the focus problem in native and foreign research recently. How to understand the frangibility of eco-environment and how to evaluate it? To forestcast the infection of environment in future is the main research. Firstly, this article analyze the evolve of eco-environment research and problem it across in native and foreign countries recently. Secondly, building an equation of eco-environment and its evaluate system based on RS technology. The research emphasize on vegetation, strive to search the genetic mechanism of eco-environment frangibility through vegetation and distill useful information from RS image in order to evaluate and ration estimate the frangibility. Using ASTER and TM image data fusion technology to ration study the frangibility of eco-environment in this area, and bring forward the evaluate model of eco-frangibility. And throughout the study of vegetation change following with landform to open out the changing rule of eco-environment following with landform. Then to evaluate the frangibility of eco-environment in Fuzhou colligate based on evaluate model and the changing rule of eco-environment following with landform. To ration describe the interface distributing feature of eco-environment frangibility and its time change feature etc.
