The eco-environmental frangibility is studied by choosing the factors of land use class change and vegetation cover rate,and the equation of eco-environmental frangibility and its evaluation system are established based on remote sensing(RS) and geographic information system technology(GIS) . Four dif-ferent years of TM images are selected to calculate land use change grads and vegetation cover rate,and the relationship be-tween the two factors and eco-environment frangibility index are build,taking Fuzhou as an example. The character of times change and space distribution of eco-environment frangibility are de-scribed. The result indicates the area of eco-environment frangibil-ity increased 2.6% in Fuzhou during twelve years,and expands from the region between infield and forest land to forest land in space distribution.
