| 摘要: |
| 生态系统功能是指生态系统维持自身或其他生态系统健康，并直接或间接为人类提供产品和服务的能力。客观评价珊瑚礁生态系统功能对实现珊瑚礁资源有效保护和可持续利用有重要意义。本研究梳理归纳了生态系统功能的概念内涵，分析了珊瑚礁生态系统功能的产生机制；初步构建了基于珊瑚礁生态系统功能指数(coral reef ecosystem function index，CREFI)的珊瑚礁生态系统功能评价方法；并以徐闻国家级珊瑚礁自然保护区为例，利用2006年和2016年调查数据对珊瑚礁生态系统功能进行定量评价。结果显示，徐闻国家级珊瑚礁自然保护区2016年的CREFI高于2006年，主要是由于珊瑚礁的死亡率有所降低和食草性鱼类种数明显增加；CREFI具有清晰的应用目标和理论框架，评价结果能清晰地反映珊瑚礁生态系统功能的时空差异，较好地评价珊瑚礁生态系统的功能稳定性和健康状况，可作为一种珊瑚礁生态系统功能定量评价模型，为珊瑚礁生态系统管理和决策提供参考。 |

| Abstract: |
| Ecosystem function refers to the ability of an ecosystem to maintain its own or other ecosystem health and to provide products and services directly or indirectly for human beings. The objective evaluation of coral reef ecosystem function is significantly important to realize the effective protection and sustainable utilization of resources. This paper analyzes the generation mechanism of coral reef ecosystem function based on the concept and connotation of ecosystem function. It provides a quantitative overall evaluation on the health and function of coral reef ecosystem integrity of Xuwen National Coral Reef Nature Reserve in 2006 and 2016 survey data using the coral reef ecosystem function evaluation method based on the coral reef ecosystem function index (CREFI). The results showed that the CREFI in Xuwen National Coral Reef Nature Reserve in 2016 was higher than that in 2006, which was mainly due to the decrease in the mortality rate of coral reefs and the obvious increase in the species of herbivorous fish. The evaluation results of CREFI with clear goals and theoretical framework of application, available and scientific evaluation data can clearly reflect the temporal and spatial variations, the healthy status and function stability of the coral reef ecosystem function. It also provides a reference for coral reef ecosystem management and decision-making as a quantitative evaluation model of coral reef ecosystem function. |
