人们越来越担心河流流域的养分和沉积物径流增加是珊瑚礁退化的潜在根源。珊瑚礁的退化可能会影响参观珊瑚礁的游客数量，从而影响依赖健康珊瑚礁创收的经济部门。本研究以澳大利亚大堡礁为案例研究，采用偶然行为方法来估计珊瑚礁退化对休闲潜水和浮潜旅行需求的影响。负二项式随机效应面板模型的结果显示，当前珊瑚礁游客从潜水或浮潜旅行中获得的消费者剩余约为每次旅行 185 澳元。此外，结果表明，鉴于珊瑚和鱼类生物多样性的假设减少，潜水员和浮潜者的珊瑚礁之旅可能会减少多达 80%。这相当于潜水员和浮潜者在大堡礁海洋公园凯恩斯管理区全日珊瑚礁旅行的旅游支出每年减少约 1.03 亿澳元。
There is a growing concern that increased nutrient and sediment runoff from river catchments are a potential source of coral reef degradation. Degradation of reefs may affect the number of tourists visiting the reef and, consequently, the economic sectors that rely on healthy reefs for their income generation. This study uses a contingent behaviour approach to estimate the effect of reef degradation on demand for recreational dive and snorkel trips, for a case study of the Great Barrier Reef in Australia. Results from a negative binomial random effects panel model show that the consumer surplus current reef visitors derive from a diving or snorkelling trip is approximately A$185 per trip. Furthermore, results indicate that reef trips by divers and snorkellers could go down by as much as 80 per cent given a hypothetical decrease in coral and fish biodiversity. This corresponds to a decrease in tourism expenditure by divers and snorkellers on full-day reef trips in the Cairns management area of the Great Barrier Reef Marine Park of about A$103 million per year.
