Spatio-temporal characteristics of NPP of forest vegetation in Fujian Province in the past 20 years
The spatio-temporal characteristics of net primary productivity(NPP)of vegetation data in Fujian Province from 2000 to 2019 were analyzed based on NPP vegetation data from moderate resolution imaging spectroradiometer(MODIS),climate data and land use data,and by using the trend analyzing,GIS analyzing and statistical analyzing methods.The results showed that:(a)In terms of time trend,both the annual average NPP and the annual total NPP in Fujian Province were relativelly stable from 2000 to 2019.(b)In terms of spatial distribution,NPP of forest vegetation in Fujian Province was heterogeneity from 2000 to 2019,among which the annual average NPP of Xiamen City was the largest,and those of the Sanming City and Nanping City were the smallest.(c)In terms of spatial trend,the NPP of 63.26%of the area in Fujian Province showed no significant change,while 12.89%of the area in southern part of Fujian Province showed significant increase and 23.85%of the area in the middle of the Province showed significant decrease,respectively from 2000 to 2019.(d)The impacts of temperature and pre-cipitation on NPP of forest vegetation showed obvious spatial differentiation in the mentioned Province.
