生态健康、生态风险、生态安全概念辨析
Conceptual Distinction of Ecological Health, Ecological Risk and Ecological Security
-
摘要: 在人类活动影响下,生态系统退化的速度越来越快,作为衡量生态系统存在状态的生态健康、生态风险、生态安全评价日益受到重视。然而,目前对于3个概念的界定不够明晰,在评价过程中指标体系混淆混用,致使理论研究也固步不前,影响了对实践的指导意义。生态健康、生态风险、生态安全的联系体现在评价主体的一致性和生态安全评价需要以生态健康评价、生态风险评价为基础;而三者的区别体现在内涵、评价对象以及评价的指标体系3个方面。Abstract: With the impacts of various anthropogenic activities, the ecosystems are degraded remarkably in different areas, so ecological health, ecological risk and ecological security, which act as measurement to value the existence state of an ecosystem, are drawing increasing attention. However, there are still no clear boundaries between these concepts, and confusion and misuse of the indicator systems even exist in the evaluation process, leading to the delay in theoretical study and assessment practice guidance. The relationship between ecological health, ecological risk and ecological security manifests in consistency between the evaluation subjects and ecological security should be evaluated on the basis of ecological health and ecological risk. Differences among the three concepts present in connotation, evaluation object and indicator system.
