北京山区野生花卉调查分析

本文以百花山、雾灵山为代表,采用生态学系统布点的方法,对北京山区的野生花卉资源进行了详细调查,引用数理统计和气候资料统计法,对一些无气象观测数据的样地进行了推算,又用逐步回归筛选出影响各种野生花卉分布的主要因子,最后用模糊相似优先比方法确定了北京山区各种野生花卉引种到城里适应度的优化链,为丰富首都北京的绿化材料提供了可靠理论依据。

On Investigation and Analysis about Wild Flowers in Beijing Mountain Area

Taking the Baihuashan and Wulingshan mountains as examples, the authors investigated the Wild Flowers(WF)resources in Beijing mountainous area in detail with acological systematic sampling method. The meteorological data of the plots where no meteorological observation was made were reckoned theoretically using statistics. And then the main factors that influence the WF distribution were sifted out by the progressive regression analysis. Finally,the optimized chain of adaptability with which the WF will be introduced from mountain to urban area was datermined. In order to enrich the Beijing's afforestration materials, this paper offers a reliable basis in terms of theory.
