中文摘要: 目前,由城市蔓延所引起的乡村景观生态安全问题及两者的互动机制还缺乏足够关注。本项目结合多学科理论,运用社会调查、GIS和RS空间分析、多维指标分析和PSR模型分析等多种定性与定量方法,从动态、可视化的角度,对城市化发展迅速的广州近20年来城市蔓延的空间演变特征,及乡村景观生态安全空间演变特征进行分析,探寻城市蔓延对乡村景观生态安全的影响规律和导致的乡村景观空间分异特征;构建乡村景观生态适宜性评价指标体系,提出基于乡村景观生态适宜度评价的城市空间增长边界;进而分析城市空间发展与乡村景观生态安全的耦合类型和特征,提出相应的空间管治和景观保护措施,构建城市精明增长和乡村景观生态安全的良性互动机制。本项目为快速城市化阶段的城乡空间格局优化提供了科学依据,也为生态城市规划及乡村景观保护等提供新的方法。

英文摘要: The rural landscape ecological security and their interation mechanism caused by urban sprawl is lack of adequate attention at present. Based on the urban geography, landscape ecology, urban planning, coupling and coordination theory and other related studies, synthetically use a variety of qualitative and quantitative methods including social survey, geographical information system(GIS) and remote sensing(RS) spatial analysis, multi-dimensional index analysis and Pressure-State-Response(PSR) model analysis, the research will firstly analyze spatial evolution characteristics of urban sprawl and rural landscape ecological security of rapid development urbanization in Guangzhou city in the past 20 years from dynamic and visual angle, to explore the impact degree of urban spraw on ecological security and how these impact lead to different spatial characteristics of rural landscape, and then establish the rural landscape ecological evaluation system, to develop a rigid and flexible boundary of urban spatial growth within ecological suitability assessment of rural landscape. Ultimately the research will analyze the spatial coupling type and feature of urban spatial expansion and rural landscape eco-security, giving corresponding spacial governace and landscape protection measures, and build up a positive interaction
