摘要
城市景观生态网络空间模式研究是生态城市和景观规划设计现今研究的重要领域之一,目的在于依据景观生态网络模式的应用建立起生态城市规划建设的基本框架和技术途径。在探讨城市景观生态系统特征和城市景观生态网络结构的基础上,总结景观生态网络空间模式并重点分析了水景树的空间生态模式、森林-道路-住宅复合网络模式、平原城市农田-灌木丛-河流交叉网络模式、岛屿城市的绿地-道路生态网络模式4种城市景观生态网络典型模式的图示特征及其生态意义。依此为理论指导基础,以都江堰为例,在继承都江堰大地景观格局并结合都江堰市灾后重建需求的前提下,研究都江堰市城市景观生态格局和生态过程,探讨在不同尺度和不同维度上运用4种网络图示进行都江堰城市景观生态网络优化调整的空间模式和对策。(1)依据"水景树图式"优化调整纵向维度景观生态格局;(2)依据"森林-道路-住宅"和"农田-灌木丛-河流"网络调整横向维度景观生态格局;(3)依据岛屿城市的"绿地-道路"景观生态网络调整城市组团景观生态格局。
Urban landscape ecological network research is one of important fields of eco-city and landscape planning researches. It aims to set a, framework and technical ways to eco-city planning and constructions according to applications of landscape eco-network spatial models. In this paper,based on the discussions of characteristics of urban landscape ecosystem and the structure of urban landscape eco-network, four typical models of urban landscape eco-network which are water-scape tree model, the mosaic of forest-road-houses, the mosaic of farmland-forest-river and greenland-road eco-network of island were chose,and the pattern, ecological functions and applications of four typical models of urban landscape eco-network were analyzed. Under the condition of earth-scape conservation and development after earthquake disaster, combined with Dujiangyan City reconstructions after earthquake disaster, as a practical study we discussed the new landscape patterns and eco-networks of Dujiangyan City with the applications of four typical models at different level and at different scale. As results,some corresponding countermeasures of the landscape eco- network planning are as following. (1)optimizing and adjusting the landscape ecological pattern at dimension of river system according to the model of water-scape tree; (2)optimizing and adjusting the landscape ecological pattern at vertical dimension with the river system according to the model of forest-road-houses mosaic and the model of farmland-forest-river mosaic; (3)optimizing and adjusting the landscape ecological pattern at the dimension of neighbor of city according to the model of greenland-road eco-network of island.
