Method for evaluating coral reef biodiversity assets

Abstract

The invention discloses a method for evaluating coral reef biodiversity assets, which belongs to the field of coral reef ecological asset accounting. The method comprises the following steps of: selecting an investigation area, carrying out reef area biodiversity investigation, calculating the biodiversity index of coral and the health state of coral reef biocenosis, evaluating the biodiversity assets of coral reefs, and analyzing the dynamic change of the coral reef biodiversity assets. The evaluation method based on ecosystem attributes is provided for coral reef biodiversity assets withoutstock capital of the market, quantitative association between ecological parameters of coral communities and biodiversity asset changes is established, and technical support is provided for more accurately knowing the current situation of coral reef biodiversity assets.

Description

technical field [0001] The invention relates to the field of coral reef ecological asset accounting, in particular to a method for evaluating coral reef biological diversity assets. Background technique [0002] Coral reefs are one of the most biologically diverse and productive ecosystems on earth, providing important ecological services such as fisheries and coastal protection for millions of people living in tropical regions around the world. According to a 2009 estimate by the United Nations Environment Program (UNEP), the total value of ecological services provided by coral reefs worldwide is more than $100 billion per year. Coral reef biodiversity plays an important role in maintaining ecosystem services. Various organisms form specific functional groups by participating in different ecological processes, and jointly complete important ecological functions. For example, in the coral reef biome: reef-building stony corals provide complex and diverse habitats for other ...

Problems solved by technology

However, this valuation method is not always justified because inshore coral reefs generally have lower biodiversity than distant coral reefs, which are more likely to provide more ecological services and products from the perspective of ecosystem attributes

It can be seen that it is difficult to reflect the natural attributes of biodiversity assets by only considering the market value, and there are certain deviations in the evaluation results
