摘　　要：为更好地促进全国油茶产量提升,推动油茶产业高质量发展,保障国家粮油安全,利用LMDI模型对油茶产量公式进行分解,从全国和分区域两个角度,定量测算单产和种植面积在2010-2021年“十一连增”期间对油茶增产的贡献,并全面探讨我国油茶增产的地域格局及贡献因素。研究结果表明:从全国而言,我国油茶产量“十一连增”是由单产提升主导的;分区域来看,核心发展区的油茶增产主要源于单产水平的提高,增产幅度达到“超速增产”水平,而积极发展区和一般发展区油茶增产则主要得益于种植面积的扩大,增产幅度分别为“滞后增产”和“同步增产”水平。其中,单产提高对油茶增产贡献更大的有6个省(区、市),而种植面积扩大对油茶增产贡献更大的有8个省(区、市);增产超过20万吨的省(区、市)是油茶生产核心区的湖南、江西、广西,增产占全国油茶增产总量的75.6%;增产层次达到“超速增产”水平的有安徽、湖南、海南、重庆、四川和贵州等6省(区、市)。最后,对油茶增产显性贡献因素的背后成因进行挖掘,对制约油茶产业发展的因素进行总结,并提出针对性意见建议。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 decompose 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 national 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 improvement of per unit yield with super-high speed,while the production increase in the active production area and general production area is mainly due to the expansion of plantation area,resulting in"lagging increase"and"synchronized 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,municipalities under the State Council)show higher contribution from expanded planting area.Hunan,Jiangxi,and Guangxi,which have increased production by over 200000 tons each,constitute the core areas of C.oleifera production,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.
