伏牛山自然保护区森林生态系统乔木层优势种种群动态

伏牛山国家级自然保护区是中国东部森林样带中的亚热带和暖温带的结合点，具有南北气候过渡带的典型特征，植被保护良好，优势种栓皮栎（Quercus variabilis）、短柄枹（Quercus glandulifera）、锐齿栎（Quercus acutidentata）和华山松（Pinus armandi）控制着山体的外貌和结构。各优势种种群多呈现为稳定型，中龄个体较多，幼、老龄个体较少，天然更新良好，种群维持着一定的后续资源；在高海拔地段，优势种种群表现为中老龄个体较多，幼龄个体较少，种群处于稳定阶段；在低海拔地段，优势种种群表现为中、幼龄个体较多，老龄个体较少，种群处于快速增长阶段。

Population Dynamics of Dominant Species in the Forest Ecosystem at Funiu Mountain National Nature Reserve

Funiu Mountain National Nature Reserve is located in the joint region of subtropical and warm-temperate zones of east China with typical north-south transition climatic. The vegetations in this nature reserve have been well protected. Four dominant tree species (Quercus variabilis, Q. glandulifera, Q. acutidentata, and Pinus armandi) were identified, which determined the appearance and structure of the mountain. The dominant populations presented stable type. More middle-age individuals were found than young and old individuals. Natural regeneration was good. At high-altitude location, more middle and old age dominant individuals were found than young individuals, populations were at stable stage. At low-altitude location, more middle, young age dominant individuals were found than old individuals, populations were at the rapid growth stage.
