- Abstract:
-
Studying on land use/cover change and its impact on ecosystem services value in Changwu County can realize the influence of human activity on regional environment. For local government, it is helpful for making reasonable land use policies to improve the local ecological environment. Years of 1990, 2000, 2005, 2010 and 2015 were selected as five time points in Changwu County during past thirty years. The land use/cover data in these years were used to analyze the trend of land use/cover types change, the rate of land use/cover types change, the transition of land use/cover types and the land using degree. Based on above analysis, the changes of ecosystem services were investigated by considering actual condition in Changwu County. The results showed that cultivated land, forestland, orchard and grassland were the main land use/cover types in Changwu County; during the study periods, cultivated land and grassland expressed a decreasing trend, while forestland, orchard, industrial land, mining land, residential land showed an increasing trend. The comprehensive utilization index decreased, which means the land use was in a state of adjustment. The land use/cover change resulted in substantial change in ecosystem services, such as, forest ecosystem service increased 62.33%, orchard ecosystem service increased nearly 8.5 times than before, and cultivated land service decreased 53.67%. In summary, the ecosystem was improved in Changwu county with the respect to increasing services in gas regulation, water conservation, biodiversity, etc.
