探讨景观生态学在城市绿地系统规划中的应用--以常州市新北区为例

景观生态学对城市绿地系统规划具有很重要的指导作用,它能够充分考虑到绿地系统景观和生态两种效应.常州市新北区濒临长江,位于其南岸.在新北区的绿地系统规划中,首先分析并指出了新北区的现状绿地存在的景观生态格局和过程缺乏连续性、绿地斑块的面积和数量偏少等一系列问题,进而以景观生态学为指导,确立了整体性与连续性、自然优先、地方精神等五条规划原则;然后确立本区域的绿地系统的空间布局结构.依据景观生态学中的尺度效应原理,根据研究需要,将新北区复杂的景观系统分成区域宏观尺度、分区中观尺度以及具体规划设计的微观尺度这三个尺度层次,利用景观生态学中相关原理分别进行研究,最终形成层次分明、在功能上相互补充、有机联系的绿地系统结构.

Exploring the Application of Landscape Ecology to Urban Green Space System Planning -- a Case Study of Changzhou Xinbei Region

Landscape Ecology is very important to the urban green space system planning and it can provide many good instructions.It can take the effect of the landscape and ecology into consideration fully.Changzhou Xinbei Region lies on the south of Yangtze River closely.In the process of making the green space system planning of Xinbei Region,firstly,the article analyzes the present situation of the green space and points out its problem,such as landscape ecological pattern and process lacking continuity,the lack of acreage and quantity of the green patch etc.Then based on the Landscape Ecology principles,it expounds five planning principles such as integrity and continuity,nature priority etc.Last,it explores the green space system composition structure of Xinbei Region.Benefiting from scale effect theory of Landscape Ecology and taking the practical situation into account,the article separates the complex landscape system of Xinbei Region into the three following scale levels: region macroscopical scale,subregion medium scale and microcosmic scale of the specific planning and design.In each scale level it uses the correlational theory of Landscape Ecology to study separately.At last it obtains the green space system structure that is very clear,supplemented in function and united organically.
