| 摘 要： | 在前人物候季节划分研究的基础上，提出了划分自然景观季节的物候频率分布型法，并利用北京小西山山前一带物候历中的资料，将当地的物候季节划分为１２个季段。划分结果表明，每个季节阶段都具有典型的植物物候形态组成与色彩组合，独特的季相特征，并且与气温和降水的季节分配状况相吻合。本方法与以往的物候季节划分方法相比，具有划分指挥定量且综合，划分季段详细，季节的内涵丰富，适用区域范围广阔等特点。

| Abstract: | In this paper the authors advance a new method called Phenological Frequency Distribution Pattern for determining the seasonality of natural landscapes and divide the phenological season in the foot area of the West Hill of Beijing into 12 stages using the data of the local phenological calendar. The result shows that each season stage has the typical morphological and coloration combination of plant phenology and the unique seasonal aspect, and is coincident with the seasonal distribution of air temperature and precipitation. Comparing this method with former methods, the new one has several characteristics, such as using quantitative and integrative indexes, determining more detailed season stages, comprising substantial season contents and having extensive regional applicability. |
