One of the main objectives of landscape ecology is to orient land-use planning by providing indications of optimal ecosystem patterning to support nature conservation. A frequent limitation to the practical use of the findings of landscape ecological studies is that they tend to focus on the identification and computation of indicators rather than on their interpretation and assessment. This paper presents and discusses the use of a methodology to formalise expert opinion through the elicitation of multi-attribute value functions. In particular, the value functions aim at assessing spatial indicators so as to provide an overall judgment of the viability of different ecosystem patches. The result consisted of the ranking of the ecosystems according to their degree of viability and therefore their suitability for nature conservation. The method of formalising expert opinion and knowledge complements traditional analyses based on the measurement of spatial ecological indicators.
景观生态学的主要目标之一是通过提供最佳生态系统格局的指示来指导土地利用规划，以支持自然保护。景观生态研究结果在实际应用中经常受到的一个限制是，它们往往侧重于指标的识别和计算，而不是对其进行解释和评估。本文介绍并讨论了一种通过引出多属性价值函数来形式化专家意见的方法的应用。特别是，价值函数旨在评估空间指标，以便对不同生态系统斑块的生存能力提供总体判断。结果是根据生态系统的生存能力程度对其进行排名，从而得出它们对自然保护的适宜性。形式化专家意见和知识的方法补充了基于空间生态指标测量的传统分析。
