The structural imbalance in agricultural functions and the uneven regional distribution of functional services are typical features of the contrasting urban and rural development.The development and transformation of agricultural functional space is an effective strategy for filling up the gap between urban and rural development and advance agricultural modernization.This paper analyzes the evaluation and status of agricultural multifunctionality in Guangdong Province by constructing an agricultural multifunctionality evaluation system.Several methods(e.g.,the coupled coordination model and spatial autocorrelation),were applied to classify agricultural composite functional spaces and to identify the evolution of agricultural composite functional spaces.Results show that the index of agricultural multifunctionality in Guangdong Province had increased from 2010 to 2020,initially slowing down before accelerating a towards non-production-led agricultural multifunctionality.This trend mainly clusters towards the coastal areas.The indices for various agricultural functions have increased,with the production functions centralizing in the eastern and western Guangdong,and further extending to the northern Guangdong.Low indices values,particularly the concentration levels,are predominantly observed in the Pearl River Delta.While the social service function has a balanced distribution at a medium level in the region,the high agro-ecological service functions in northern Guangdong indicates the formation of an ecological barrier in the area.The leisure service function is mainly clustered in the Pearl River Delta region,showing the characteristics of high-high concentration and low-high concentration.Agricultural composite function space type has been transformed to ecological and leisure composite function space,forming a new pattern of production-ecological service,production-social service,production-leisure service,social-leisure service,social-ecological service types.In Guangdong Province,agricultural multifunctionality continues to integrate and diversify the types of composite functional space and as such there is regional disparities in the pattern of agricultural functions.Therefore,this paper proposes that the development and transformation of agricultural functional space should be planned in a holistic manner.Agricultural development should be balanced with ecological protection to support the coordinated development of agricultural functional space in accordance with local conditions.This research serves a theoretical basis for the optimization of the spatial pattern of agricultural functional space in Guangdong Province,promoting intensive and efficient use of agricultural space,and fostering integrated development of urban and rural areas.
