concluded in accordance to InVEST and other biophysical Our study revealed that the ESV of Wuhan increased
models that the ESV in China increased between 2000 from 119.32 billion yuan in 1996 to 220.30 billion yuan in
and 2010 (Ouyang et al., 2016). Therefore, on the national 2018, showing an overall upward trend. For the trend of
scale, although there were increases and decreases in change, the results in this study are consistent with some
the ESV in China according to the research by different related research results, such as those by Liu & Yang (2021)
scholars, the degree of change was relatively small. Many and Zhang et al. (2018). However, there are also a few
studies on the impact of land use change on ESV, which studies that are inconsistent with the results of the present
had been carried out in different areas and cities in China,
produced many research results. Some studies point out study (Chen et al., 2021), showing a decreasing trend in the
that land use change caused by the natural environment value of ecosystem services. The reasons for this difference
and human activities would lead to the loss of ESV, while are that the data used were different, and the research
others indicated an increase (Ye et al., 2018). This finding methods were also different. Most studies have shown that
indicated the existence of large spatial heterogeneity with the increase of forestry area and water area, the ESV
in ESV. in Wuhan had increased to varying degrees.
