南海珊瑚礁经济价值评估
Economic Valuation of the Coral Reefs in South China Sea
摘要
Abstract
Based on the basic data, foreign literature and field data, the economic values (including fishery, coastal protection, tourism and biodiversity) and economic losses (from overfishing, destructive fishing and sedimentation) of the coral reefs in South China Sea are calculated in this paper with the effect of production method and numerical transferring method. The results show that the potential sustainable annual economic value of the coral reefs in South China Sea is RMB 156.5×108 Yuan. Among them, the fishery value attributes 90 percent, which is RMB 140.4×108 Yuan. The coastal protection value is 8.7×108 Yuan, accounting for 5.5 percent of the total. And tourism and biodiversity values are lower, respectively, 5.3×108 Yuan and 2.1×108 Yuan. If we assume that the coral reefs could keep the condition in next 20 years in future with a discount rate of 10 percent per year, the total economic value of the region would be 1 370×108 Yuan. As the most prevalent threat to coral reefs in South China Sea is unreasonable use by human beings, the total economic loss in the next 20 years would be 258.8×108 Yuan. Destructive fishing is the activities bringing the most financially detrimental to coral reefs in South China Sea and resulting in massive economic and societal losses, which are estimated to be 249.6×108 Yuan, about 96.4 percent of the whole value loss. Economic damage from overfishing and sedimentation in reefs would be 3.3×108 Yuan and 5.9×108 Yuan, respectively. The overexploitation and overuse of reefs in South China Sea make economic losses sharply, which would reach about 18.98 percent of the total sustainable economic value in the future 20 years.关键词
