Based on the research background of China 's important agricultural cultural heritage perspective (China-NIAHS), this paper takes the landscape of the ancient jujube forest in Lingbao City, Henan Province as the research object, and uses the landscape pattern index analysis method in landscape ecology to analyze spatial pattern characteristics of the ancient jujube forest in Lingbao City. The results show that: (1) Jujube forest accounts for the largest proportion of all landscape types. Jujube forest, as the dominant landscape type in the study area, plays a supporting role in the study of landscape pattern characteristics in the whole area. (2) The spatial distribution of jujube forest is closely related to the distribution of roads and settlements in the study area. The jujube forest accounts for a large proportion of the total landscape area in the study area. From the characteristics of the number of patches, it can be seen that the jujube forest has low fragmentation and the landscape distribution is concentrated. (3) From the landscape shape index, it can be seen that the complexity of jujube forest patches is low, the artificial effect is obvious, and the shape is regular; in addition, from the analysis of the spatial adjacency characteristics of the landscape, the correlation between the distribution of jujube forest landscape and other landscape elements can also be proved again. The research results have certain guiding and reference significance for the protection and development of agricultural cultural heritage, the development and utilization of agricultural landscape resources and rural revitalization.
