Vegetation cover change and driving factors in Fujian Province between 1975 and 2014

Abstract

Aims Fujian Province has been one of the most severe soil erosion regions since Ming and Qing Dynasty in China. Recently, several ecological restoration projects have been implemented and they have significantly changed vegetation cover in this region. Methods We analyzed the four-decade vegetation cover change in Fujian Province using seven time-series data of Landsat Multispectral Scanner (MSS), Thematic Mapper (TM), and Operational Land Imager (OLI) between 1975 and 2014. We further explored the possible drivers on vegetation cover change by incorporating statistical data of plantation, cropland and urbanized area. Important findings Vegetation coverage in Fujian Province has increased from 69.0% to 77.8% between 1975 and 2014. However, a slight decrease was observed between 1995 and 2005. Spatially, forest was the primary vegetation type in the northwest, where croplands and human settlements were scattered along rivers or oceans. Shrubs and bare lands were also scattered across the northwest. In southwest, the areas of bare land, shrub land and cropland decreased, while areas of forest and human settlements expanded. The vegetation coverage and urbanized area increased at the cost of cropland and bare land.
