With the well-developed theory and methodology of landscape security pattern, and by the analysis of natural, biological, and cultural processes, it's possible to judge and plan the landscape security pattern of definite ecological process, i. e., to maintain the minimum ecological land use of this ecological process both in pattern and in area, which is of strategic significance. From the aspects of land coverage and spatial quality, this paper defined the ecological land use as the ecosystem (land unit) and its spatial position that have important significance in safeguarding critical ecological processes and providing critical ecosystem services. Taking three towns in eastern Beijing as an example, the ecological land use based on storm water management and biological conservation was analyzed. In the study area, the ecological land use at low, medium, and high security levels occupied 20.4%, 31.1%, and 48.6% of the total, respectively, indicating that the landscape security pattern approach based on critical ecological processes was an effective tool in the quantitative study of ecological land use, having important reference value for urban and land planning.
随着景观安全格局理论与方法的不断完善，通过对自然、生物和文化过程的分析，能够判断和规划特定生态过程的景观安全格局，即在格局和面积上维持该生态过程的最小生态用地，这具有重要的战略意义。本文从土地覆盖和空间质量方面，将生态用地定义为对维护关键生态过程和提供关键生态系统服务具有重要意义的生态系统（土地单元）及其空间位置。以北京东部三个城镇为例，分析了基于雨水管理和生物保护的生态用地。在研究区域内，低、中、高安全水平的生态用地分别占总面积的20.4%、31.1%和48.6%，表明基于关键生态过程的景观安全格局方法是生态用地定量研究的有效工具，对城市和土地规划具有重要参考价值。
