Effects of land-use change on ecosystem service values in Xiong’an New Area from 1995 to 2019

In the study of sustainable development of urbanization, the spatiotemporal study of urban ecosystem service values (ESV) is of great significance. Taking Xiong’an New Area as an example, based on four remote sensing images from 1995 to 2019, the land use dynamics and the ESV of Xiong’an New Area were analyzed by using land dynamic degree and value equivalent factor. The results showed that: the cultivated land and construction land in Xiong’an New Area changed greatly from 1995 to 2019, and their proportions changed from 70.55% and 10.29% in 1995 to 62.80% and 20.30% in 2019, respectively; the proportion of woodland, waters and grassland was relatively small, but the range of changing was more dramatic. From 1995 to 2015, the ESV in the study area showed a decreasing trend, with a decrease of 1.917 billion yuan, and an increasing trend from 2015 to 2019. Spatially, the area of wetland ecosystems with higher ESV in Xiong’an New Area showed a trend of decreasing first and then gradually increasing, which was consistent with the ESV trend of Xiong’an New Area. In general, the main driving factor for the changing of ESV in Xiong’an New Area was water area. In the future urbanization process, Xiong’an New Area should pay more attention to the protection of Baiyangdian Lake and promote the coordinated and sustainable development of ecology-economic-society.
