Abstract: From the perspective of the integration of cultural landscape constitution and cultural ecology and based on the integrity of cultural heritage proposed by Jukka Jokilehto, we introduced the conception of "cultural ecological integrity" according to organically evolved cultural landscape, which emphasizes the continuity and effectiveness in the work progress of natural environment and social environment to cultural landscape. We also listed 3 features and 4 manifestations on ecological integrity of cultural landscape. Further, we proposed and expounded the principles and standards, methods, index model for evaluating the integrity degree of cultural landscape, and described the definitions of indicators in the evaluation. Finally, we classified the ecological integrity of cultural landscape in five levels through the index system and evaluation method, providing theoretical basis and practical operation for the targeted classification protection and sustainable development of future cultural landscape.
