Community structures and species diversity in natural and man-made Pinus yunnanensis forests in central Yunnan were investigated. The results showed that, fewer interferential natural Pinus yunnanensis forest had the most stable and reasonable community structures, populations of the dominant species of tree stratum had the strongest ability in naturally regenerating and succession potential, and also the species diversity and habitat diversity were the most abundant. The features of fewer interferential natural forest described above were all superior to that of the more interferential natural Pinus yunnanensis forest; and more interferential natural forest preceded forest plantation. The more the interference (both natural and artificial) increased during the originating process of the forests, the more the community stability, biodiversity, harmonious and balanced capacity and renewing capacity declined. However, the distribution range and quantum of the invasive species Ageratina adenophora increased in a
