This paper introduces the method of remote sensing model for ecologicalchange monitoring and evaluation after forest fire.According to the investigation of regeneration and ecological change of Yunnan Pinus fire slashes by remote sensing inPanxi

it analyses spatial distribution and change regular of ecofactors and determinesmajor ecofactors and its evaluation criteria. Basing on remote sensing information andthe result of fuzzy synthetical evaluation to eight factors or topography soil

stand anddegree of deforestation and the years after forest fire

creats remote semsing model forecological change monitoring and evaluation after forest fire.This model makes usachieve expected purpose.For forest ecological dynamic monitoring system by remotesensing

it’s discussed that the data of monitoring factors and vegetation index areabtained.
