| Abstract: | Based on Landsat data in 2018 with a resolution of 30 meters,meteorological data in 2001 and 2010,and forest resource monitoring data in 2018 in Huzhou,Zhejiang province,estimation was made on spatial distribution characteristics of net primary forest productivity(NPP)by CASA model.Results showed that the mean annual NPP in Huzhou was about 7.49 t/ha.The spatial distribution of NPP increased with altitude.The difference in geographic and ecological environment of the same forest type had deviation in NPP estimation.Because of small area of soft broad and shrubs,their inversion accuracy was low,and the estimation deviation was larger than that of other forest types.NPP estimation results of different forest types in Huzhou were similar to those in other cities. |
