文摘Over the past decade,biomass burning has emerged as one of the main polluting events in northern India.It is one of the major sources of brown carbon(Br C),the light-absorbing organic carbon component of PM_(2.5).Most studies on the impact of biomass burning in India are based on source locations or urban areas;very little is known about its effects on a regional background location.We examine the effect of biomass burning on regional air quality and co-occurring meteorological factors.Year-long PM_(2.5)levels and light absorption by carbonaceous aerosols at 880 nm and 370 nm were measured at Rohtak,a regional background location.Results showed that post-harvest biomass burning in the Punjab-Haryana region affects the regional air quality with a lead of one to two days.A comparison of dispersionnormalized concentrations showed that open-field biomass burning not only affects regional air quality in the post-monsoon season(kharif crops)but is also a dominant source of PM_(2.5)in the post-harvest summer season(rabi crop).A significant(p<0.05)difference is observed in PM_(2.5),b_(abs-880),and b_(abs-370)between biomass burning days and non-biomass burning days during the kharif and rabi harvest seasons.Regression analyses confirm that in summer,regional PM_(2.5)and light absorption by aerosols are influenced more strongly by post-harvest burning of rabi crops.However,adverse meteorology plays a more dominant role in the post-monsoon season than biomass burning.These findings underscore the need for better policy interventions to curb biomass burning and improve air quality during both harvest seasons.
文摘The“One Zone,Two Lands,One Park,and One Corridor”development strategy implemented in Guangxi,as a key component of China’s regional strategic deployment,provides opportunities and challenges for the development of local higher education.By comparing the strategic requirements,this paper uses the SWOT analysis method to conduct an in-depth analysis of the current status of higher education in Guangxi.The analysis results show that Guangxi’s higher education has certain advantages in geographical location but lacks educational resources.At the same time,the region’s higher education faces opportunities such as policy support and local industrial transformation and upgrading,but it also faces risks such as fierce external competition,mismatches between talent supply and demand,and financial constraints.Aiming at the above problems,this paper further proposes the Opportunity Capture Strategy,Adversity Breakthrough Strategy,Advantage Defense Strategy,and Disadvantage Resolution Strategy,aiming to solve the problems faced by regional higher education in serving the transformation of local development strategies.
