发布时间：2018-10-10 17:46
【摘要】：近年来,长株潭城市群中城市区域化与区域城市化非常迅速,处于长沙、株洲、湘潭三市中心地带的生态绿心地区生态环境受到严重的威胁。如何保护生态绿心的生态环境,阻挡城市空间蔓延,为城市群提供生态服务,遏制区域城市化的趋势,是目前长株潭城市群生态绿心地区发展的严峻挑战。 本研究以长株潭城市群生态绿心地区为例,在城乡规划过程中构建和谐的具有可持续特征的城市景观生态网络格局,促进城市景观生态系统功能、生态屏障功能的发挥,为城乡规划和城市发展提供不同维度和尺度空间上的可操作性依据,主要从以下三个方面进行研究。 1.对景观生态学中斑块一廊道一基质和景观连接度等理论以及国内外城市景观生态网络的典型模式进行了分析阐述,指出了城市景观生态网络应用中存在的问题及发展新趋势。 2.为构建可持续的城市景观生态网络格局,促进城市景观生态系统功能的发挥,以长株潭生态绿心地区为例进行了生态敏感性分析、生态服务功能重要性评价等生态分析,对其现状景观生态网络进行了分析。 3.运用斑块、基质、廊道三大景观空间要素,以及水景树空间生态模式、“农田-灌木丛-河流”交叉网络模式,充分考虑点、线、面有机结合,构建“一心多斑块多廊道”的景观生态网络结构。
[Abstract]:In recent years, the urban regionalization and regional urbanization in Changsha-Zhuzhou-Xiangtan urban agglomeration are very rapid, and the ecological environment in the ecological green heart of Changsha, Zhuzhou and Xiangtan is seriously threatened. How to protect the ecological environment of ecological green heart, prevent the spread of urban space, provide ecological services for urban agglomeration and curb the trend of regional urbanization are the severe challenges for the development of ecological green core area in Chang-Zhu-Tan urban agglomeration at present. Taking the ecological green heart region of Changsha-Zhuzhou-Xiangtan urban agglomeration as an example, a harmonious and sustainable urban landscape ecological network pattern is constructed in the process of urban and rural planning to promote the function of urban landscape ecosystem and ecological barrier. For urban and rural planning and urban development to provide different dimensions and dimensions of the operational basis of space, mainly from the following three aspects of research. 1. The theories of patch-corridor-matrix and landscape connectivity in landscape ecology and the typical models of urban landscape ecological network at home and abroad are analyzed and expounded. This paper points out the problems existing in the application of urban landscape ecological network and the new trend of development. 2. In order to construct a sustainable urban landscape ecological network pattern and promote the function of urban landscape ecosystem, ecological sensitivity analysis and ecological service function evaluation were carried out in Changsha-Zhuzhou-Xiangtan ecological green heart area. The present situation of landscape ecological network is analyzed. 3. Using the three landscape elements of patch, matrix and corridor, as well as the spatial ecological model of waterscape tree and the cross network model of "farmland, shrubbery and river", fully considering the organic combination of points, lines and surfaces, Construct the landscape ecological network structure of "multi-plaques and multi-corridors".
