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)
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 odinary least square (OLS) with geographical weighted regression (GWR).

The Olympic Games are not only a grand event in the field of sports but also involve the display and competition of a country's comprehensive strength and image on the international stage. Therefore, every Olympic Games has become more like a "battlefield" for the media of all countries. Due to the increasing number of media outlets participating in reporting, different styles of reports have followed. The reasons behind these reports have covered political, economic, and cultural fields and have had a huge impact. This paper will study the framework construction, direction, and concept of mainstream media coverage of the 2022 Beijing Winter Olympic Games in China and the United States and analyze the reasons for their formation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
