By the investigation of Pinus tabulaeformis f. shekannesis community in Fu County, Shaanxi, the community can be carried on cluster analysis and divided into four types with STATISTICA software: namely the P. tabulaeformis f. shekannesis forest of Lespedeza bicolor, P. tabulaeformis f. shekannesis forest of Cotoneaster multiflorus, P. tabulaeformis f. shekannesis forest of Indigofera bungeana , P. tabulaeformis f. shekannesis forest of Sophora davidii, and the age structure of characteristics increasing slowly, renewal under stand characteristics of seedlings high supplement but young trees high death rate, the law of adjacency effect taking place in young stand were analyzed. Meanwhile, a development trend of this stand towards stability was forecasted.
