【摘要】：近年來,長株潭城市群中城市區(qū)域化與區(qū)域城市化非常迅速,處于長沙、株洲、湘潭三市中心地帶的生態(tài)綠心地區(qū)生態(tài)環(huán)境受到嚴(yán)重的威脅。如何保護(hù)生態(tài)綠心的生態(tài)環(huán)境,阻擋城市空間蔓延,為城市群提供生態(tài)服務(wù),遏制區(qū)域城市化的趨勢,是目前長株潭城市群生態(tài)綠心地區(qū)發(fā)展的嚴(yán)峻挑戰(zhàn)。 本研究以長株潭城市群生態(tài)綠心地區(qū)為例,在城鄉(xiāng)規(guī)劃過程中構(gòu)建和諧的具有可持續(xù)特征的城市景觀生態(tài)網(wǎng)絡(luò)格局,促進(jìn)城市景觀生態(tài)系統(tǒng)功能、生態(tài)屏障功能的發(fā)揮,為城鄉(xiāng)規(guī)劃和城市發(fā)展提供不同維度和尺度空間上的可操作性依據(jù),主要從以下三個方面進(jìn)行研究。 1.對景觀生態(tài)學(xué)中斑塊一廊道一基質(zhì)和景觀連接度等理論以及國內(nèi)外城市景觀生態(tài)網(wǎng)絡(luò)的典型模式進(jìn)行了分析闡述,指出了城市景觀生態(tài)網(wǎng)絡(luò)應(yīng)用中存在的問題及發(fā)展新趨勢。 2.為構(gòu)建可持續(xù)的城市景觀生態(tài)網(wǎng)絡(luò)格局,促進(jìn)城市景觀生態(tài)系統(tǒng)功能的發(fā)揮,以長株潭生態(tài)綠心地區(qū)為例進(jìn)行了生態(tài)敏感性分析、生態(tài)服務(wù)功能重要性評價等生態(tài)分析,對其現(xiàn)狀景觀生態(tài)網(wǎng)絡(luò)進(jìn)行了分析。 3.運(yùn)用斑塊、基質(zhì)、廊道三大景觀空間要素,以及水景樹空間生態(tài)模式、“農(nóng)田-灌木叢-河流”交叉網(wǎng)絡(luò)模式,充分考慮點(diǎn)、線、面有機(jī)結(jié)合,構(gòu)建“一心多斑塊多廊道”的景觀生態(tài)網(wǎng)絡(luò)結(jié)構(gòu)。
[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".
