Abstract
Based on field investigation of Pinus sylvestris var. mongolica in Qiqian,the community structure,distribution patterns and species diversity of Pinus sylvestris var. mongolica community have been analyzed. The results showed:( 1) The density of Pinus sylvestris var. mongolica forest are 830 stocks/hm2,780 stocks/hm2,580stocks/hm2. The diameter distribution is in unimodal and multimodal distribution,the height distribution is in unimodal mountain and multi- peak shape distribution.( 2) The distribution patterns of three sample plots in Qiqian are aggregated distribution.( 3) The richness index of Pinus sylvestris var. mongolica community is herb layer arbor layer shrub layer,the diversity index of Pinus sylvestris var. mongolica community is herb layer shrub layer arbor layer,and the law of evenness index isn't obvious.
