基于能值分析的舟山市生态系统健康评估

Energy-Based Urban Ecosystem Health Assessment: A Case Study of Zhoushan

摘要: 一个健康的生态系统是稳定的和可持续的，在时间上能够维持它的组织结构和自治，也能够维持对胁迫的恢复力。能值理论为经济建设与自然环境建立了一个沟通的桥梁。本文用能值分析方法，建立了应用于对舟山市生态系统健康的评估指标，指出舟山作为旅游城市组织结构尚不完善，环境负荷大，生态系统承载力逐年降低，因此仍需从降低环境胁迫入手，逐步降低城市生态系统干扰，使其恢复力得以提高，增加系统反弹恢复的容量，使之恢复维持结构与格局的能力，实现城市健康和谐发展。

Abstract: A healthy ecosystem is stable and sustainable, can maintain organizational structure and autonomy and has resilience to stress by itself. The emergy theory builds a bridge of communication between economic development and natural environment. This paper uses the emergy analysis method to establish evaluation indicators of ecosystem health of Zhoushan, pointing out that zhoushan as a tourist city organization structure is not perfect, environmental load is heavy, and that ecosystem carrying capacity reduces year by year. That’s why we need to start with reduce environmental stress, gradually reducing the interference of urban ecological system, which greatly improves the restoring force, increases the capacity of system bounce back, restores one’s capacity to maintain structure and pattern, and realizes the healthy and harmonious development of the city.
