To this end, we mapped the dynamics of land cover and the condition of vegetation as well as ecosystem services based on remote sensing data for the period of 1992–2020, to quantify these changes in Huangyan district, Taizhou, China. The results show a dramatic increase in urban area over the 28-year timeframe, i.e. 265% growth in Huangyan district. This rise was particularly evident in the period of 2015–2020. The huge expansion in urban area came at the cost of arable land. To compensate the resulting loss of farmland, large-scale natural ecosystems such as forests, grasslands and wetlands were continuously transformed into arable (as well as urbanized) land. Despite the dramatic reduction in green space as a result of urbanisation, we found a slight increase in the overall mean NDVI value for Huangyan, mainly due to the improved condition and density of remaining forest area in the western countryside. Further, we evaluated the provision of ecosystem services (ESS) by adapting an existing assessment methodology elaborated by Burkhard et al. (2012). The results show that ESS supply continually fell in Huangyan since 1992, reflecting a reduction of green space. The highest ecosystem capacity is seen in recreation and biodiversity due to the large proportion of forested area. Our findings serve as an important basis for further investigations in the region of Huangyan by framing the general issue of green space dynamics and highlighting specific developments of ecosystem distribution and change as well as ESS supply.
The members of the inter- and transdisciplinary funding priority »Sustainable Development of Urban Regions« publish their research results in various types of publication, that are appropriate for the respective research and implementation. In addition, the funding priority itself issues different formats of publication in which the international researchers of SURE publish their results.
