指标提供了有关感兴趣对象的状况或条件的简单快捷的信息，因此在决策中得到广泛使用。近年来，政策对脆弱性研究的兴趣有所增加，越来越多的研究旨在制定脆弱性指标。其中一些研究是在社会生态系统框架内进行的，同时考虑到社会脆弱性和生态脆弱性。然而，面临的一个特别挑战是如何纳入指标以反映后者，特别是因为生态学中适用的脆弱性概念相对较新，尚未得到充分探讨。本文通过回答以下问题来阐述这一问题：（1）目前人们对脆弱性以及生态脆弱性的概念是如何理解的？(2)在制定和使用生态脆弱性指标方面有哪些挑战？(3)目前为克服这些挑战作出了哪些努力？一种观点认为，由于自然系统的复杂性、非线性和动态多样性，可能无法制定足够普遍的生态脆弱性指标。相反，生态脆弱性评估及其指标的制定，无论是独立于人类系统还是在社会经济系统内进行，都应该在较小的规模上进行，而且必须针对具体情况。(C)2015爱思唯尔有限公司版权所有。
Indicators provide easy and quick information on the status or condition of an object of interest and are therefore widely used in policy-making. In recent years, policy interest in vulnerability research has increased and a growing number of studies have been aimed at developing vulnerability indicators. Some of these studies have been done within the social-ecological system (SES) framework, taking into account both social vulnerability and ecological vulnerability. A particular challenged faced, however, is with regard to the incorporation of indicators to capture the latter, especially as the concept of vulnerability as applied in ecology is relatively new and not yet well-explored. This paper expounds on this problem by answering the following questions: (1) How are the concept of vulnerability and thereby ecological vulnerability currently understood? (2) What are the challenges in the development and use of ecological vulnerability indicators? (3) What are the current efforts to overcome these challenges? One insight gathered is that due to the complexity, nonlinearity, and multiplicity of dynamics of natural systems, development of sufficiently general indicators of ecological vulnerability may not be realizable. Rather, ecological vulnerability assessment and the development of indicators thereof, whether done independent of the human system or within the SES, should be conducted at smaller scales and must be context-specific.
