基于景观生态学的城市绿地空间格局优化——以合肥市为例

城市绿地是城市生态系统的重要组成部分，发挥着不可替代的生态功能。而其生态服务功能的强弱取决于绿地空间规划的科学性、合理性。运用景观生态学理论，以合肥市为例，在分析城市绿地现状的基础上，对城市绿地景观格局优化进行了探讨。基于景观生态规划最优化原则，立足于斑块-廊道-基质的景观基本构型，提出保护城市生态用地、建设绿色廊道网络和增加绿地斑块的景观格局优化途径。文章旨在探讨合肥这一园林绿化质量层次较高的城市，如何在城市快速发展进程中，更好地发挥城市绿地的生态效益，实现城市生态环境的可持续发展。

Optimized Layout of Urban Green Space Based on the Theory of Landscape Ecology: A Case Study of Hefei

Urban green space is the main part of urban landscape with important ecological functions. The ecological function of the system depends on science and rationality of its planning. Green space of Hefei city has been planned as a case study based on theory of landscape ecology in this paper. By the analyzing the existing problems of the green space of the city, a series of strategies about urban green space optimization have been put forward. This paper aims to study how to realize sustainable development of Hefei city by exerting ecologic function of urban green space against the background of rapid urbanization.
