结构性矛盾的加剧是转型期社会的一大特征,而矛盾的加剧或多或少会催生出社会个体的负面情绪。新媒体平台相对抹除了现实社会中的等级差别与地位差异,使得用户有机会通过点赞、转发、评论等媒介参与行为激发情感共鸣并建立新的价值认同... 结构性矛盾的加剧是转型期社会的一大特征,而矛盾的加剧或多或少会催生出社会个体的负面情绪。新媒体平台相对抹除了现实社会中的等级差别与地位差异,使得用户有机会通过点赞、转发、评论等媒介参与行为激发情感共鸣并建立新的价值认同与身份认同,由此产生的"同类感"促使用户在虚拟世界建立起新的社群以寻求情感的慰藉和自我价值的实现。但由受众"抱团取暖"搭建起来的虚拟社群难以维系其平等属性,在话语权力、身份认同、资本参与等诸多因素的综合影响下,虚拟社群实际上走向了新一轮的社会分层过程。 展开更多

[Objective]Study on carbon sink effects in Conversion of Farmland to Forest Project in Hongfenghu drainage basin in order to provide evidences for assessing carbon sink potential of conversion of farmland to forest in Guizhou Province.[Method]By investigating the implement of Conversion of Farmland to Forest Project in Hongfenghu drainage basin from 2000 to 2006,the carbon sink amount and effect of seven main tree species in the foreat region like Cunninghamia lanceolata,Cryptomeria fortunei,Amygdalus persica,Prunus salicina,Armeniaca vulgaris,Camptotheca acuminate and Catalpa bungei were calculated,based on which the amount of forest carbon sinks in Hongfenghu drainage basin in 2015 was estimated.[Result]Biomass storage and carbon sink amount in middle and young aged forests were increasing over time from 2000 to 2006,which reached 1.05×107 kg by 2006 and would engage more and more potential.Cunninghamia lanceolata has the superior carbon sink capacity in the seven tree species in the research region,of which the amount of carbon sink per unit area will be 106.51 t/hm2 by 2015,followed by Cryptomeria fortunei with the amount of carbon sink per unit area by 99.42 t/hm2.Armeniaca vulgaris has the weakest carbon sink capacity of all the seven species with the amount of 13.03 t/hm2.The total amount of carbon sink in seven tree species was 2.35×107 kg,while the average amount of carbon sink per unit area was 26.17 t/hm2,which could produced economic benefit of 7.17×106 yuan calculated on the price of 305.0 yuan/t or 5.91×106 yuan calculated on the price of 254.1 yuan/t.[Conclusion]Economic benefits of carbon sink effects of Conversion of Farmland to Forest Project in Hongfenghu drainage basin were great with huge appreciation potential. 展开更多
