The Influences of Various Factors and Interest Demands on Linpan Landscape Evolution in the Chengdu Plain: A Qualitative Study based on Oral Histories

Traditional rural homegarden agroforestry systems in the Chengdu Plain of China are often referred to as “Linpan” in Chinese, which integrates the landscape of ecological functions and human production activities. In recent years, due to the influences of urbanization and the aging population, the Linpan landscape has changed dramatically. Clarifying the factors which influence Linpan landscape evolution is a critical way to improve rural landscape renovation. Through oral history interviews, the deep-seated factors driving the evolution of the Linpan landscape form from 1949 to 2020 are explored using the grounded theory. The results show that in the process of Linpan landscape evolution, beneficiary groups, the material basis, and cultural characteristics are the prerequisites for changing the Linpan settlement landscape. The demand of production and life and government-led behavior are the two main influencing factors, and landscape change is the final result. The demand of production and life from the residents is the primary internal driving force of landscape change, while government-led behavior is the main external driving force of settlement development and evolution. The nature of the main driving forces behind the evolution of the Linpan landscape in the Chengdu Plain can be divided into three stages. (1) From 1949 to 1980, it was characterized as a balancing of government forces and social forces. (2) From 1981 to 1993, it was characterized by social forces suppressing government forces. (3) From 1994 to 2020, it was characterized as a stalemate between the government and social forces. From the perspective of the evolution of the Linpan settlement landscape, the traditional Linpan form and settlement layout have been unable to meet the new requirements of the rural social and economic transition period. They are facing the challenges of rural reconstruction and rural revitalization. In the future, village and town planning and the design of new settlements need to comprehensively consider the demands of different interest groups.
