天津市区景观生态及物种多样性

天津市区的景观生态系统,由于受地域、气候等因素的限制,品种比较单一,春、夏、秋三季缺乏彩色,冬季缺乏绿色。为了改变这种现状,可以结合春季干旱、夏季炎热、冬季寒冷、降水量少且不均匀的气候特点,根据乔灌草混合立体栽种的绿化美化原则,因地制宜地引进一些适合本地环境和气候条件的具有"彩色"、"长绿"和"香味"特点的美化绿化树种,和本地的传统树种搭配种植,达到优化城市生态系统、丰富植物种群和提高观赏效果的目的。根据各种植物对光的补偿点不同的原理,最大限度地创造绿量,让城市生态环境向良性循环的方向发展。

Tianjin Urban Landscape Ecosystem and Species Variety

Restricted by terrain, climate and so on, varieties of the landscape ecosystem of the Tianjin urban system is comparatively simple, less color in spring, summer and autumn,and lack of greeness in winter. According to the virescence and beautification principle of the three-dimensional afforestation, some colorful, evergreen and fragrant virescence trees were introduced which can adapt to the local environment and climate which is drought in spring,torridity in summer, cold in winter, fewer rainfall and lack of symmetry, and plant with the original trees to improve the condition of single variety, enrich the plant population and increase the ornamental result to change the present situation. According to the principle of various kinds of plant with the different compensation point to light,the virescence was enlarged to the maximum extent and the urban ecological environment was developed in the direction of bengin cycle.
