Based on the survey data of Juglans mandshurica and Larix principis-rupprechtⅡ mixed forest plot in Baihua Mountain Nature Reserve, and by using the uniform angle index, neighborhood comparison and mingling degree, this paper analyzed the spatial structural characteristics of J.mandshurica and Larix principis-rupprechtⅡ mixed forest in the reserve. The results showed that J.mandshurica had the obvious advantage in population density and basal area, being the dominant and constructive species of the tree layer. The average mingling degree of the forest was 0.382, suggesting the low mingling degree of stands. The dominant species was mainly none-or less-mixed, while the accompanying species were generally well-mixed. In the spatial structural units, J.mandshurica and Larix principis-rupprechtⅡ populations were mainly of dominant, sub-dominant, and intermediate trees respectively, while the advantages of other populations were not obvious. The spatial pattern of the stands was of aggregative distribution.
