Impact of Land Use Change on Ecosystem Services in Urban Forest Park
The characteristics of land use change in Shanghai Bay National Forest Park from 2000 to 2018 were quantitatively analyzed by using the land dynamics and landscape pattern analysis,and the e-cosystem service value equivalent method.The evolution of the landscape pattern and the ecosystem serv-ice value were evaluated,and the correlation between land use change,landscape pattern and ecosystem service value was discussed.The results showed that the land use types in the study area changed rapidly from 2000 to 2018,with significant fluctuations in the area of vegetation,roads,and farmland.Forest land and roads increased rapidly,while farmland decreased rapidly,showing a trend of"two more and one less".The dominant landscape matrix shifted from farmland patch type to forest patch type.The landscape types gradually developed from fragmented and uneven state to balanced state.The total ESV increased from 86.595 1 million yuan in 2000 to 13.412 42 million yuan in 2018,with an increase of 54.89%.Water bodies and vegetation were the main land types providing ecosystem service value,and the value of regulating service value was at a significantly higher level compared with the other three serv-ice types.The increasing number of patches,the increasing area of dominant landscape types such as for-est land and water body,the diversification and equalization of landscape types made the value of ecosys-tem services in the study area increase continuously.There was a strong positive correlation between the intensity of changes in ecosystem service value and the intensity of land use.
