Abstract:
【Objective/Meaning】Through the analysis of the characteristics of NDVI in Fujian Province from 2000 to 2017, the changing trends of vegetation coverage in Fujian were studied from the macro perspective.【Methods/Procedures】Using ArcGIS and Excel software, the MOD13Q1 NDVI data set, NDVI of three main land types and DEM data of Fujian Province from 2000 to 2017 were processed and analyzed by trend line, stability and superposition analysis.【Results/Conclusions】The annual and seasonal NDVI of Fujian showed steady growth from 2000 to 2017, and the area of vegetation slightly or significantly improved was over 70.00% of the total area; The NDVI of grassland, cultivated land and forest land in Fujian Province were improved in the interannual variation in the past 18 years. Among them, the improved area of forest land and grassland exceeded 70.00% of the corresponding land type area with significant increasing trend; The vegetation area with NDVI variation coefficient less than 5.00% in Fujian Province was 59.09% in recent 18 years, indicating high stability; The NDVI of Fujian increased with the elevation, and the growth rate increased firstly and then slowed down with the increase of elevation.
