Abstract

The coral reef ecosystem plays an important role as a provider of ecosystem services and has various economic benefits to the coastal community. However, the coral reefs ecosystem continues to degrade by 19% globally. This degradation caused some coastal and archipelagic countries have developed methods of calculating coral reef health index, including Indonesia. However, some literature shows that there is no common standard method for coral reef health index as the analysis depends on the data availability and the purpose of the study. Remote sensing technology that currently provides much open-source data is a potential method /tool to calculate the health index of coral reefs if the required parameters are met. This article review aims to identify remote sensing data used in the existing coral health indexes and then analyze the integration of all spatial data for coral reef health index calculation. Reference searches are sourced from the SCOPUS database combined with search engines Harzing and Mendeley. There are five coral reef health index calculation models from 25 references consisting of 19 publications and six reports out of 209 filtered references using keywords of Coral Reef Health Index. As a result, coral reef cover and algae are commonly used data obtained from remote sensing imagery. However, remote sensing technology cannot estimate other important parameters such as fish biomass. In addition, physical information of the waters, such as sea surface temperature (SST) and water clarity indicators (turbidity and diffused attenuation coefficient), are parameters contained in the five indexes that can be obtained from remote sensing data. In general, the literature review shows that coral reef health indicators (e.g. index or individual benthic cover) are significantly related to the various parameters affecting coral reef degradation such as algae cover, rubble cover, SST and river plump either as an individual or multivariate factors.

基于遥感数据的珊瑚礁健康指数计算综述

珊瑚礁生态系统作为生态系统服务的提供者发挥着重要作用，对沿海社区具有各种经济效益。然而，全球珊瑚礁生态系统继续退化19%。这种退化导致一些沿海和群岛国家开发了计算珊瑚礁健康指数的方法，包括印度尼西亚。然而，一些文献表明，由于分析取决于数据的可用性和研究的目的，珊瑚礁健康指数没有统一的标准方法。目前提供大量开源数据的遥感技术，如果满足所需参数，是计算珊瑚礁健康指数的潜在方法/工具。本文旨在识别现有珊瑚健康指数中使用的遥感数据，然后分析所有空间数据的整合，以计算珊瑚礁健康指数。参考搜索来自SCOPUS数据库，结合搜索引擎Harzing和Mendeley。使用珊瑚礁健康指数关键词的25篇参考文献包括19篇出版物和209篇过滤文献中的6篇报告，共得到5个珊瑚礁健康指数计算模型。因此，珊瑚礁覆盖和藻类是常用的遥感影像数据。然而，遥感技术无法估计鱼类生物量等其他重要参数。此外，海水的物理信息，如海表温度(SST)和水体的清澈度指标(浊度和扩散衰减系数)，是可以从遥感数据中获得的五个指标中包含的参数。总的来说，文献综述表明，珊瑚礁健康指标(如指数或个体底栖生物覆盖)与影响珊瑚礁退化的各种参数(如藻类覆盖、碎石覆盖、海温和河流丰度)无论是作为个体因素还是多因素，都具有显著的相关性。
