Abstract Taking 128 administrative villages in Wannian County, Jiangxi Province as the research object, from 2010 to 2018 as the research time point, this paper constructs multi-functional evaluation index system of rural areas from three dimensions — production function, living function and ecological function, quantitatively measures the functional intensity of rural areas, and systematically analyzes and depicts the temporal variation and spatial differentiation process of the functional intensity of rural areas in Wannian County by the methods of trend surface analysis, spatial autocorrelation and cold hot spot analysis. The results show that from 2010 to 2018 the time difference and spatial differentiation characteristics of various functions index in rural areas of Wannian County were obvious and the local agglomeration effect was significant, but the overall regional differences narrowed. In the future, it is important to classify development of regional villages and enhance their leading function so as to achieve sustainable rural development.

乡村是一个地域的概念, 指城市以外的一切地域[1]。乡村地域系统是在人文、资源、经济与环境等要素的交互作用下形成的具有一定结构和功能的特定空间体系[2], 通过与外界发生能量、物质和信息的交换来实现自身的发展、停滞、衰退或消亡。随着乡村经济的发展和转型, 乡村正在由静态的地域空间向复杂动态的地域空间演化[3], 其功能属性

从最初的农业生产和居住承载演变到如今兼具生产、生活、生态和文化等多重属性[4]。乡村地域功能指乡村地域系统在特定社会发展阶段, 通过与外界的交互作用表现出利于自然界或人类可持续发展的综合特性[5–6], 多功能性是其本质特征。《乡村振兴战略规划(2018—2022年)》指出, 要遵循乡村发展规律, 科学地把握乡村差异和发展走势分化特
