通州运河森林公园植物景观季相 风貌研究

：以通州运河森林公园作为研究对象，通过卫星影像 结合现场调查收集数据，并构建采用相应指数进行季相景观风 貌分析，结果表明：1)公园中植物种类共117种，以群落为 主的空间形态分布；2)春季以花景为主，红花景、黄花景、 白花景分别由碧桃、连翘、白蜡主要表征，垂柳表征芽景； 红花景与芽景分散分布，黄、白花景相对聚集分布；3)夏季 以花景为主，红花景、黄花景、白花景分别由木槿、国槐、 红瑞木主要表征，红花景与白花景聚集分布，黄花景相对分 散分布；4)秋季以叶景为主，由栾树主要表征，金银忍冬主 要表征果景，叶景在秋季相对分散分布；果景相对聚集分布； 5)冬季以叶景为主，主要由油松表征叶景，花景相对分散分 布。果景、枝景相对聚集分布；6)基于季相景观可从路径调 整与游线建议两方面优化提升路径系统。

Study on Seasonal Appearance of Plant Landscape in Tongzhou Canal Forest Park

Taking Tongzhou Canal Forest Park as the research object, the data were collected by satellite imaging combined with field investigation, and the corresponding index was constructed to analyze the seasonal landscape features. The results showed that: 1)117 species of plants in the park distribute in a community-based spatial form; 2) Flowers dominate in spring. Red flower, yellow flower and white flower landscape are mainly characterized by Amygdalus persica , Forsythia suspensa and Fraxinus chinensis , while the bud scenic spot is characterized by Salix babylonica; the red flower and bud landscapes are dispersed, the yellow flower and white flower landscapes are relatively aggregated; 3) Flowers dominate in summer, and the red flower, yellow flower and white flower landscape are mainly characterized by Hibiscus syriacus , Sophora japonica and Swida alba , respectively. The red flower and white flower landscape are aggregated, while the distribution of yellow flower landscape is relatively dispersed; 4) Leaf landscape is dominant in autumn, which is mainly characterized by Koelreuteria paniculata and Lonicera maackii mainly characterizing fruit landscape. Leaf landscape is relatively dispersed in autumn, while fruit landscape is relatively aggregated; 5) Leaf landscape is dominant in winter, which is mainly characterized by Pinus tabuliformis, and leaf landscape and flower landscape are relatively dispersed. Fruit and branch landscape is in relative aggregation distribution; 6) Based on seasonal landscape, upgrading path system can be optimized from two aspects of path adjustment and route suggestion.
