Influence of meteorological factors on ecosystem services value: a case study of Beijing-Tianjin-Hebei region, China

Abstract

Meteorological factors are one of the natural factors, which affect ecosystem services value (ESV). Influence of meteorological factors was studied in Beijing-Tianjin-Hebei region using ordinary least square (OLS) with geographical weighted regression (GWR). The main aim of this study was to reveal the differences in the influence mechanism at the global and local levels. The main meteorological factors influencing ESV were temperature and precipitation, followed by humidity. Days with annual daily precipitation≥0.1mm, annual minimum precipitation and annual average relative humidity were three important meteorological factors. Annual temperature range, annual minimum precipitation, days with annual daily precipitation≥0.1mm, in particular, the last one had an obvious positive effect. The positive and negative effects of annual average relative humidity were coexisting, and the negative effect was the main. It was obvious that the spatial distribution characteristics of the local influence mechanism. The local model of GWR can better solve the spatial non-stationarity of the dependent and independent variables, thus it was better than the global model of OLS. The results also provide detailed field information on the different effects of meteorological factors at different locations.E3S Web of Conferences 158, 06003 (2020)

Assessment of the impact of the Three Gorges Project on the ecosystem service value

“…For instance, based on observations of global vegetation, researchers identify 15 instances of shifts in biomes since the 18th century, which were attributed to changes in temperature and precipitation. Simultaneously, the distribution of terrestrial ecosystems is signi cantly regulated by the variations in the climate (Guo et al, 2020;Yao et al, 2022;Zhu et al, 2020).…”
