- Abstract:
-
Landsat TM images of three periods containing years of 2005, 2010 and 2014 in the western mountainous area of Luanchuan county were used to extract the land use change data by using supervised classification and man-computer interactive interpretation method. Based on the scale of Chinese land ecosystem service value put forward by Xie Gaodi, in combination with the practical situation of Luanchuan County, we revised the equivalent table of ecosystem service values and calculated the effects of land use change of 14 towns in Luanchuan County on ecosystem service value sand the changes. The results showed that:(1) during the period of study, the changes of cultivated land, forest land and grassland areas of Luanchuan County were not significant, the construction land area showed the increasing trend, and water area increased first and then decreased; (2) the ecological service value of Luanchuan County increased dramatically from 2005 to 2010, it went back down to the level of 2005 in 2014; (3) every sensitivity coefficient of land ecological service value was less than 1; the sensitivity coefficient decreased in the order:forestland > water area > grassland > farmland, and the contribution of woodland to ecosystem service value was the highest, while the contribution rate of farmland was the lowest. Ecological service value was lack of elasticity to ecosystem service function indexes, and the results were credible.
