Abstract

Environmental Change, climate changing and land used changing will affect NPP in Jiangxi
Province from 2000 to 2018 based on GLO-PEM model and meteorological data, the special
distribution, change and influencing factors of vegetation NPP in Jiangxi Province were
analyzed, according to Meteorological and Satellite Remote Sensing Monitoring, since 2000,
the ecological quality of vegetation in Jiangxi has been continuously improved. In 2018, the
vegetation coverage in Jiangxi province increased by 18.4% compared with 2000, the highest
since 2000; the Vegetation Index (NDVI) was the second highest in nearly 20 years; and the
NPP (NPP) increased by 14.7%, the best since 2000. Based on GLO-PEM model, the following
measures should be taken to maintain the superiority of ecological civilization construction in
Jiangxi Province: (1) continue to increase the coverage of vegetation in Jiangxi Province; (2)
improve the quality of forest vegetation and enhance the productivity of vegetation; (3) to
promote green ecological agriculture and fruit industry, enhance the carbon sink function of
agriculture and fruit industry, take measures to reduce the use of chemical fertilizers and
pesticides, and reduce soil and water loss in farmland and orchards; (4) scientifically dealing
with the impacts of extreme weather and climate events and meteorological disasters on the
vegetation ecosystem.
