无序扩张和环境质量恶化是城市发展所面临的重要挑战，研究城市绿地系统规划有助于提高城市生活品质，维持城市生态系统的稳定、健康发展。利用城市化水平较高的杭州湾滨海城市慈溪市为研究对象，并运用绿色基础设施理论及GIS技术，分析了城市绿地现状及其空间分布所存在的问题。提出优先保护城市生态的目标，规划了城市绿地连接通道，整合非线性绿地网络中心，全面提升了城市保障与生态环境维护的系统功能。

英文摘要：

Every city faces disordered expansion and environment worsening. Researching urban green land system planning will contribute to improve people＇ s living quality, and maintain the stability and healthy development of urban ecosystem. Taking Cixi city in Hangzhou bay area as an example, this paper analyzes problems of green land conditions and spatial distribution based on the green infrastructure theory and Geographic Information System （GIS） technique. The goal of preferentially protecting urban ecology is presented. The connection corridors of urban green land are planed. The nonlinear green land network centers are integrated. Therefore, the system function of city maintenance and ecological environment protection is completely improved.
