Abstract

In this paper, we obtained the changing curves of the meteorological elements (temperature, the percentage of sunshine, monthly precipitation) and NDVI of post-fire in Heilongjiang in 1987. Then through the light use efficiency model, we calculated NPP of post-fire in the recovery period by the data of remote sensing satellite and meteorological elements. Finally, we had summarized that the recovery cycle of the vegetation was long after fire based on the analysis of NDVI and NPP. It needed a few years or decades to recover. Specifically, NDVI and NPP significantly increased in the first few years after fire, since then became stable and showed a slow rise tendency.
