Abstract: Greenway is an opportunity for mitigating the planning issues in Maozhou valley, to connect, separate and buffer the  town space. By means of dividing the space into regular grid，the greenway intervenes grid in order to form ecological corridor connecting nature space and create buffering zone separating city space and nature piece, so that the space optimization strategy will be proposed. Finally, based on analyzing effect of greenway which have been built, it is clarified that future greenway construction should realize the connecting of different types greenway and form green traffic network to promote watershed town space optimization.

Key words: Greenway, Shenzhen Maozhou River watershed, space optimization, regular grid

摘要： 深圳茅洲河流域城镇用地布局不合理、自然空间建设不足，绿道在城镇空间中具有连接、隔离和缓冲作用，为城镇空间优化带来了契机。论文对流域进行规则式网格划分，将绿道介入网格形成生态廊道连接自然空间，通过绿道生成缓冲区隔离和缓冲城镇用地与自然斑块，并提出以网格为单元的空间优化策略。最后分析已建绿道在城镇空间中的作用，阐明未来绿道建设旨在实现不同类型绿道的无缝衔接，从而形成绿色交通网络来促进流域城镇空间的优化。
