| According to the data of the land cover types from the west of the Jilin Province in 1980,1995 and 2010,using the Chinese terrestrial ecosystems unit area ecological services value as scale to make a research about spatiotemporal dynamic changes of ecosystem services value of the west of Jilin Province for nearly 30 years.The results show that the ecosystem services value of the west of Jilin Province gradually reduce from 1980 to 2010, from RMB 50024.13 million to RMB 44 088.62 million , the change rate is -11.9%; from the 1980 high in the middle surrounded by low pattern gradually transformed into a pattern of high northern southern low; spatial pattern of ecosystem services toigh -value areas by the state led to a low -value gradually transformed into a state dominated area, high - high autocorrelation type showed a trend of decreased significantly, and low - low autocorrelation type showed a trend of increase, the global spatial autocorrelation index increased first and then decreased; the centroid value of ecosystem
services moved to the northeast 12.5 km in general.Artificial reclamation activity is dynamics in spatial and temporal change of ecosystem service value of the west Jilin Province. |
