摘要: 生态系统可持续性是指生态系统持久地维持或支持其内在组份、组织结构和功能动态健康及其进化发展的潜在和显在能动性的总和.它是由生态整合性、自维持活力、自调节力和自组织力所构成的1个四元能力体系.生态系统持续性是由系统自身的组份、结构和功能动态来体现的.因此,对系统组份、结构和功能动态的辨识和评估是测度生态系统持续性的方法论基础.本文提出了1个由12项测度内容和30多类测度变量组成的生态系统可持续性的指标度量框架,反映了生态系统持续性的基本特点.从测度方法上看,基于指标的测度方法是生态系统持续性的基本测度方法,但它需要和整合测度方法相结合,以便提供一个完整的测度途径.

Abstract: Ecosystem sustainability is defined as the capacity of ecosystem in sustaining or maintaining the health and evolution of its components, structures and functions which consists of the capacities of ecological integrity, self maintenance, self regulating and self organization. As ecosystem sustainability is emerged by its components, structures and functions, a methodological basis of measurement should be established by their identification and assessment. In this paper, an indicator based framework of measurement with 12 items and more than 30 variables is presented to indicate the essential dynamic attributes of sustainable ecosystem. Although such an indicator based approach is very necessary for the measurement of ecosystem sustainability, it needs to be combined with integrated methods of measurement to establish a complete system for measuring ecosystems of sustainability.
