| 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 ecosystem
service value equivalent method. The evolution of the landscape pattern and the ecosystem service
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 service
types. The increasing number of patches, the increasing area of dominant landscape types such as forest
land and water body, the diversification and equalization of landscape types made the value of ecosystem
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. |
