【摘要】：本文以天津市海河滨河景观为研究对象，采用实地调查法对海河两岸9个桥段18个样地进行调查，调查的内容主要包括滨河区的驳岸形式、植物种类科属、频度、生活型、观赏特性等，并分析海河两岸滨河景观的现状和存在的问题。 调查表明： （1）18个样地的护岸在(断面)形式上分，包含4种形式，最多的是矩形断面有8个样地，其次是矩形双层断面有6个样地，第三就是组合双层断面有4个样地，自然形断面只有1个样地，比例为8:6:4:1。 （2）18个样地主要观赏植物共有82种，属于34个科60个属，而乔、灌、草分别为40、20、22，比例为2:1:1.1。82种观赏植物在观赏特性上分，观花植物44种，观叶植物34种，观形植物18种，观果植物17种，观枝植物仅有9种，其植物景观的应用特点是：以落叶阔叶树为主，伴以常绿落叶型的自然式与规则式相结合的外貌。 （3）对18个样地中乔、灌、草频度进行分析，发现乔木类出现频度较高的有国槐、银杏、白蜡、石榴、紫叶碧桃、金银木、红叶李7种，灌木类有连翘、金叶女贞、大叶黄杨、紫叶小檗4种，草本类有早熟禾、狗尾巴草、萱草3种，，而只出现过1次的植物有35种。可以看出最常用的观赏植物主要集中在14种，有利于植物种类多样性的形成，并形成丰富优美的植物景观。 （4）通过对天津市海河两岸滨河植物景观进行分析，发现滨河植物景观类型分为密林式植物滨河景观带、模纹花坛滨河景观带、疏林草地型植物滨河景观带三个类型。
[Abstract]:In this paper, the waterfront landscape of Haihe River in Tianjin is studied, and the 18 plots of 9 bridge sections on both sides of the Haihe River are investigated by field investigation method. The contents of the investigation mainly include the forms of barge, plant species, genera, frequency, life type in the riverside area. Viewing characteristics, and analyzing the current situation and existing problems of riverfront landscape on both sides of Haihe River. The survey showed that:. (1) the revetment of 18 sample plots is divided into four forms, the most common being the rectangular section with 8 sample plots, followed by the rectangular double-deck section with 6 sample plots, and the third with the combined double-deck section with four sample plots. The natural section has only one plot, with a ratio of 8: 6: 4: 1. (2) there are 82 species of ornamental plants in 18 plots, belonging to 34 families and 60 genera, while trees, shrubs and grasses are 40 / 20 / 22 respectively. The proportion of ornamental plants is 2: 1: 1.1.82. There are 44 species of flowering plants, 34 species of foliage plants and 18 species of ornamental plants. There are 17 species of fruit-watching plants and only 9 species of branch-watching plants. The application characteristics of the plant landscape are as follows: deciduous broad-leaved trees, accompanied by the appearance of natural and regular patterns of evergreen and deciduous trees. (3) by analyzing the frequency of Arbor, shrub and grass in 18 plots, it was found that there were 7 species of Arbor, such as Sophora japonica, Ginkgo biloba, white wax, pomegranate, purple leaf and green peach, honeysuckle, red leaf plum, and shrubs, such as Forsythia suspensa, goldleaf privet, large leaf yellow poplar. There are 4 species of purple leaf berberis, 3 species of bluegrass, 3 species of dogtail grass and 3 species of hemerocallis, while 35 species of plants have only appeared once. It can be seen that the most commonly used ornamental plants are mainly concentrated in 14 species, which is conducive to the formation of plant species diversity. And form a rich and beautiful plant landscape. 4) through the analysis of the riverside plant landscape on both sides of the Haihe River in Tianjin, it is found that there are three types of the waterfront plant landscape types: the dense forest plant riverside landscape, the model flower bed riverside landscape and the sparse forest grassland plant riverside landscape.
