- Abstract:
-
It is urgent to investigate the spatiotemporal variation of carbon storage in coastal zone ecosystem of Jiangsu Province since the reform and opening up in China with respect to harmonizing the environment with economic development. The remote sensing images which date from the year of 1975 to 2007 were acquired. The integrated valuation of environmental services and tradeoffs (InVEST) model was utilized to evaluate the amount of carbon storage in coastal zone of Jiangsu Province. Long time series of carbon storage data were built. The spatial analysis method was used to investigate the spatial correlation of the ecosystem services and to explore the pattern of spatiotemporal variation. Some basic conclusions can be drawn from the experimental results. The total amount of carbon storage increased while the amount of carbon storage per unit area decreased. The amount of carbon storage in this area presented highly spatial agglomeration and obvious relevance. Specifically, the amounts of carbon storage in Yuntaishan Mountain of Lianyungang City,floodplain of Xinyi River,coastal reeds of Yancheng City were high while those in cities and towns were low.
