1 The framework design and empirical study of Chinas marine ecological-economic accounting
طرح چارچوب و مطالعه تجربی از حسابداری اقتصادی زیست محیطی دریایی چین-2021
In recent years, the Chinese government has attached greater importance to marine ecological protection. To contribute to scientific understanding of the importance of marine ecosystems to human well-being, this paper analyzes marine ecosystem service and its accounting, and introduces the concept of “quaternary industry” on the basis of current marine economic accounting framework. Marine ecosystem accounting, marine economic accounting and marine ecological-economic accounting of coastal areas in China during the time series of 2005–2017 are calculated. The results show that compared with Gross Ocean Product (GOP), the average annual growth rate of Gross Marine Ecological-Economic Product (GMEEP) stays stable. The proportion of the added value of quaternary industry in marine ecological economy is relatively large, which is between 46% and 51%. And the ratio of GMEEP and GOP is around 1.9, suggesting a quite close association between GMEEP and GOP.

2 Mapping the global value and distribution of coral reef tourism
نقشه برداری ارزش جهانی و توزیع گردشگری صخره مرجانی-2017
Global coral reef related tourism is one of the most significant examples of nature-based tourism from a single ecosystem. Coral reefs attract foreign and domestic visitors and generate revenues, including foreign exchange earnings, in over 100 countries and territories. Understanding the full value of coral reefs to tourism, and the spatial distribution of these values, provides an important incentive for sustainable reef management. In the current work, global data from multiple sources, including social media and crowd-sourced datasets, were used to estimate and map two distinct components of reef value. The first component is local “reef-adjacent” value, an overarching term used to capture a range of indirect benefits from coral reefs, including provision of sandy beaches, sheltered water, food, and attractive views. The second component is “on-reef” value, directly associated with in-water activities such diving and snorkelling. Tourism values were estimated as a proportion of the total visits and spending by coastal tourists within 30 km of reefs (excluding urban areas). Reef-adjacent values were set as a fixed proportion of 10% of this expenditure. On-reef values were based on the relative abundance of dive-shops and underwater photos in different countries and territories. Maps of value assigned to specific coral reef locations show considerable spatial variability across distances of just a few kilometres. Some 30% of the worlds reefs are of value in the tourism sector, with a total value estimated at nearly US$36 billion, or over 9% of all coastal tourism value in the worlds coral reef countries.
