中文摘要：

传统城市总体规划偏重城市物质空间规划而较少重视城市生态规划，在人类生存环境压力日益增大的时代背景下，城市总体规划应当有所突破。陕西省定边县城市总体规划引入景观生态学理论，将景观生态学思想贯穿于城市总体规划始终。规划将城乡物质空间规划与城市景观安全格局规划统一考虑，对宏观景观格局进行分析，并制定中观层次景观格局规划导则，同时，对中观景观体系（斑块-廊道-基质）中各元素进行规划前后相关数据的’比较，为探索景观生态规划在小城市总体规划中的运用提供可资借鉴的案例。

英文摘要：

Typical city master plans prioritize physical planning above ecological planning. These master plans must address environmental deterioration. Concepts of landscape ecology are included in the Dingbian master plan to integrate physical planning with an ecologically appropriate landscape layout. The plan analyzes the macro landscape layout of the city and provides guidelines for an intermediate landscape layout. The comparison of the current and planned （patch- corridor-matrix） layouts provide a good example for ecological master planning in other small cities.
