Abstract: AbstractL: This paper aims to explore the dynamic protection and adaptive management strategy of agricultural heritage through the relationship between conception of nature and cultural expression. Based on revealing relationship between the Yi’s view of trees and cultural expressions, this paper studies the modern value of the Yi’s tree culture and its cultural heritage and development. The research shows that the Yi people’s concept of trees as the core of their culture reflects major concerns for their living environment; it affects the expression form of the Yi’s tree culture. Because the Yi’s tree culture has modern ecological and economic value, the sustainable development of the Yi regions needs to reconstruct the cultural expression with “tree” as characterization with modern element, based on the conception of nature. Making the traditional conception of nature play its role on the ecological environment provides not only the framework and thoughts for the overall protection of the agricultural heritage, but also the standard and principle which the agricultural heritage can follow to adapt to modern times.
