Centennial Change and Source–Sink Interaction Process of Traditional Agricultural Landscape: Case from Xin’an Traditional Cherry Cultivation System (1920–2020)

Abstract

In contrast to modern agriculture, long-standing traditional agricultural practices such as agricultural heritage systems (AHS) are important inspirations for promoting harmonious human–land relations. However, some AHS have been in danger as their traditional agricultural landscapes (TALs) were changed by rapid modernization and urbanization. Thus, how do we figure out the change processes? What conservation measures can be taken? Taking the Xin’an Traditional Cherry Cultivation System in the loess hilly areas of Henan Province as a case, this study introduced the source–sink landscape theory to analyze the structure and process of the TAL during 1920–2020. Results show that, during 1920–1950, the traditional rural landscape (TRL) and the agricultural (natural) ecological landscape (ANEL) in the TAL were relatively balanced because they were source and sink to each other. Since 1985, the source expansion and sink resistance of both TRL and ANEL have been greatly hindered by the sink growth of modern village landscapes (MVL). As the core source landscape, TRL needs salvage protection for inheriting local characteristics by effective measures. TAL conservation should highlight rurality preservation through expanding the protection scope of TRL, endowing the MVL with more indigenous cultural features, etc. All these may contribute to rural vitalization and sustainable development.
