Analysis on the pattern and contributing factors of increasing Camellia oleifera production in China
摘要
Abstract
In order to facilitate the increase in national Camellia oleifera production,promote the high-quality development of the C.oleifera industry,and ensure national grain and oil security.Using the LMDI model to decom-pose the yield formula of C.oleifera,quantitatively calculate the contribution of unit yield and planting area to the production increase of C.oleifera during the"11th consecutive increase"period from 2010 to 2021,both at a nation-al and from regional perspectives,and comprehensively explore the regional pattern and contributing factors of C.oleifera production increase in China.The results are as follows:Nationally,the production increase is dominated by the improvement of per unit yield;Regionally,the increase in the core production area is mainly due to the improve-ment of per unit yield with super-high speed,while the production increase in the active production area and gener-al production area is mainly due to the expansion of plantation area,resulting in"lagging increase"and"synchro-nized increase"levels respectively.Among them,6 provinces(autonomous regions,municipalities under the State Council)demonstrate higher contribution from increased per unit yield,while 8 provinces(autonomous regions,mu-nicipalities under the State Council)show higher contribution from expanded planting area.Hunan,Jiangxi,and Guangxi,which have increased production by over 200 000 tons each,constitute the core areas of C.oleifera produc-tion,accounting for 75.6%of the total increase nationwide.6 provinces(autonomous regions,municipalities under the State Council),including Anhui,Hunan,Hainan,Chongqing,Sichuan,and Guizhou,have reached the level of super-high speed in terms of production increase.To conclude,the underlying causes of the explicit contributing factors to the production increase of C.oleifera were explored,the factors that constrain the development of the C.oleifera industry were summarized,and targeted suggestions were proposed.关键词
