【摘要】 由于城市的不断发展,人类生活水平的不断提高,对于城居环境的要求也在不断的发生变化,再者由于城市发展的迅速,然而发展过程中又缺乏对于自然的保护,因此共同促成了如今对于绿色健康可持续发展的人居环境的追求。城市中高楼林立,充斥着太多的人工迹象明显的混凝土结构,人工改造与自然成分之间的比例严重不足,同时城市发展规划的不合理,使得自然斑块不足,岛屿化程度越演越烈,因此。作为改善城市环境,连接城市绿心等斑块景观结构的城市绿色廊道的建设成为重要的课题之一,但是建设中仍然还存在不少问题。本研究介绍了绿色廊道的相关概念,以及相关的景观生态学理论。同时,介绍了分析绿色廊道及网络的相关景观指标并提出了绿色廊道网络的规划目标,包括绿色廊道宽度的确定、走向以及总体布局。同时对于绿色廊道内部结构进行了分析与研究,包括廊道内部植物种类的选择以及配置形式的合理搭配。结合实际,分析与研究常德市绿色廊道网络景观结构。通过对常德市自然社会条件的调查与了解,以及结合影像资料提取该城市廊道的现状分布图形信息,通过各项指标的计算与分析,总结出常德市绿色廊道网络存在的不足：绿色廊道在总量上存在一定的不足；同时各类廊道宽度设置过窄,且廊道内部植被配置形式单一；而绿色廊道网络连通度低,环路不多,且廊道未能有机的串联起城市的各个绿心；绿色道路廊道中绿色分车带建设不足、行道树在树种选择上较为单一、且不注重乔灌草三者的合理搭配,立体效果不足。最后结合相关景观生态学理论,对常德市绿色廊道网络结构提出合理的规划建议。包括常德市绿色廊道宽度、走向的确认、绿色廊道内部植被配置形式,以及总体上的布局,以求发挥出绿色廊道对于城市环境保护以及生物多样性方面的生态效益,使得绿色廊道网络有助于城市景观改善以及城市的生态建设。更多还原

【Abstract】 With the development of the city, people need the better city environment. Due to the urban development is over rapid and lacking of the nature protection,people persuiting to the living environment that more sustainable,green and health.the building in the city filled with too much artificial obvious signs of concrete structure, the proportion of the artificial and natural is imbalance,and also the urban planning is not reasonable,it makes atural plaque is insufficient and the degree island getting worse, in conclusion,as a role that can improve the urban environment and link to the city green heart,Corridor construction is becoming one of the important issues.but,the processing of the corridor construction exist many problems.The research introduced the related concept of corridor and theory of landscape ecology.;Meanwhile,Introduced landscape index about analysising the green corridor and network, raised the green corridor network planning goals Including corridor width, orientation and overall layout; researched the corridor internal structure Including plant species choice of internal and reasonable collocation of configuration forms.Connect the reality, the paper analysised and researched green corridor network landscape structure of changde city. Through investigating the social and natural conditions of Changde city and thought combining with GPS graph extracting the present corridor situation of the city, calculating and analysising the indicators, Sumed up the corridor network’deficiency of Changde city:in total,Green corridor number is certain lack, corridor width is set too narrow, And internal vegetation of the corridor with a single form. The corridor network connectivity is low, and the loop circuit is absence.and the corridor failed to connect the city green heart, the tree species selection of street is relatively single.collocation of trees shrubs and cover is not reasonable, Lacking the stereo effect.Based on the related theory of landscape ecology,This paper put forward the reasonable planning advice of the corridor network structure of Changde city, Including corridor width and orientation of Changde city, and corridor internal vegetation configuration forms And the general layout. In order to make the corridor playing a role that benefits to the environmental protection and biological diversity for the city, Make green corridor network helps to improve the urban landscape and ecological construction of the city.更多还原
