Abstract:The spatio-temporal changes of ecosystem service value (ESV) and the determination of its driving factors are the basis of ecosystem service management and decision-making. Based on the remote sensing monitoring data of land use/land cover in six periods of 2013, 2015, 2017, 2019, 2021 and 2023, the remote sensing ecological index and ESV of the Beijing-Tianjin-Hebei region were calculated, and their spatio-temporal evolution, profit and loss situations and driving factors were analyzed. The research finds that during the research period, a large amount of cultivated land in the Beijing-Tianjin-Hebei region was transformed into other land use types, among which the area of cultivated land that could not penetrate water surfaces and grasslands was the largest. The overall change of ESV shows a trend of first decreasing and then increasing. The spatial distribution of ESV shows that it is higher in mountainous areas than in plain areas, and higher in coastal areas than in inland areas. From 2013 to 2023, the ESV change index in the Beijing-Tianjin-Hebei region generally showed a trend of first decreasing and then increasing. Especially during the period from 2017 to 2023, the most gain was obtained within the study area. The analysis of the profit and loss situation of ESV indicates that the changes in ESV in the Beijing-Tianjin-Hebei region present a trend of first loss, then gain, and then stabilization. Compared with natural factors, socio-economic factors have a stronger impact on ESV, especially per capita GDP and night light intensity play a key driving role in it. Meanwhile, the HAI value generally shows an upward trend. In regions with strong economic vitality such as Beijing and Tianjin, the intensity of human activities is relatively high, and they reached peaks of 0.7466 and 0.6801 respectively in 2023. The results of the interactive detection show that the effects of each factor on the ecosystem service value of the study area present two-factor enhancement and nonlinear enhancement, indicating that the ESV in the Beijing-Tianjin-Hebei region is not only affected by each driving factor alone, but also by the superposition of driving factors. The research results have provided a reference basis for the coordinated development of the ecological environment and regional economy in the Beijing-Tianjin-Hebei region.
