| 摘 要： | 应用理论拟合、聚集强度指数分析方法对不同封育时间蒙古栎林样地内的主要乔木种群进行研究，结果表明：蒙古栎、黄榆种群均为聚集型分布；蒙古栎和黄榆种群的聚集强度在不同封育时间内表现不同的变化．总体上看种群聚集强度均呈下降趋势．在封育初期，黄榆种群比蒙古栎种群的聚集强度更大，随着封育时间的延长，黄榆种群的聚集强度下降，呈扩散趋势． |

| Abstract: | s:The spatial patterns of main arbor populations in Q. mongolica forest with different times of forest conservation were modeled, all displaying aggregated distribution. Results showed that Q. mongolica and Ulmsis laciniata populations were aggregated distribution; they displayed different degrees of aggregation intensity during different times of forest conservation; aggregation intensity of populations inclined as a whole. During initial stages of forest conservation, the aggregation intensity of U. laciniata population indicated greater than that of Q. mongolica, and the aggregation intensity of U. laciniata population declined and diffused gradually with prolonged times of forest conservation. |
| Keywords: | forest conservation Q mongolica forest distribution pattern |
