Abstract: In our research,uniform angle index and neighborhood comparison were applied to different densities of Mongolian pine plantation to analyze their stand structure characteristics.The results showed that (1) Evenness distribution was the main spatial characteristics for the most of stands,and number of trees in the core area decreases with the density increasing.(2) The neighborhood comparison measured by branch angle was a visibly higher,thus,it is possible to evaluate the ranch angle index to achieve its predominance status among individuals competition and to enhance its effect on desertification.The conclusions of this study can provide important support for afforestation and forest management in this region.

Key words: Pinus sylvesiris var.mongolica, artificial forest, uniform angle index, neighborhood comparison
