Problems solved by technology

However, the existing methods have the following problems: 1) They are all based on survey, observation or research data, and are static evaluations of the value of ecological services
It cannot reflect the spatial heterogeneity of ecosystem wealth, and cannot reflect the impact of large-scale small-scale changes (such as climate change) and small-scale large-scale changes (such as large-scale deforestation in the region, drainage of natural wetlands in the region, etc.) influence of wealth
2) The existing methods have inconsistent understanding of the value of terrestrial ecological wealth, mainly because of the lack of price

Embodiment Construction

[0020] The technical solutions of the present invention will be further described in detail below in conjunction with specific embodiments.

[0021] see Figure 1-3 , an algorithm for assessing terrestrial ecological wealth, including the following steps:

[0022] 1) Calculation of direct ecological wealth EWD i ; direct ecological wealth EWD i The calculation is the product provided by the terrestrial ecosystem, that is, the economic value of food and raw materials for human direct or indirect use;

[0023] 2) Calculation of indirect ecological wealth EWI i ; indirect ecological wealth EWI i It is the economic value provided by the supporting services, regulating services and cultural services of the ecosystem, including gas regulation, climate regulation, water conservation, soil formation and protection, waste treatment, biodiversity maintenance and entertainment culture of the ecosystem, a total of 7 services the value of;

[0024] 3) Terrestrial ecological wealth ca...

Abstract

The invention discloses an algorithm for evaluating land ecological wealth. The algorithm comprises the following steps: 1) direct ecological wealth EWDi is calculated, wherein the direct ecological wealth EWDi calculates a product provided by a land ecological system; 2) indirect ecological wealth EWIi is calculated, wherein indirect ecological wealth EWIi is an economic value provided by supportservice, regulation service and culture service of an ecological system; and 3) the land ecological wealth calculates benefits directly and indirectly obtained from the ecosystem function by human beings, and the indirect ecological wealth EWIi and the direct ecological wealth EWDi are added to obtain the total wealth EWi of the ecosystem. The invention provides a quantifiable evaluation index ofthe service value of the land ecosystem, and provides an important tool for ecological benefit evaluation of natural resource and ecological environment auditing, ecological restoration, ecological engineering and major decisions.

Description

technical field [0001] The invention relates to the field of evaluating ecological wealth, in particular to an algorithm for evaluating terrestrial ecological wealth. Background technique [0002] Terrestrial ecological wealth refers to the total value of ecosystem materials and services provided by terrestrial ecosystems and their ecological processes, and is a monetized quantitative evaluation of the value of ecosystem services. In 1981, Ehrlich et al formally defined the impact and effectiveness of ecosystems on human society as "ecosystem services". Costanza (1997) and Daily (1997) successively further clarified the definition and connotation of ecosystem services, pointing out that ecosystem services represent the benefits that humans obtain directly or indirectly from ecosystem functions, including the products and services provided by ecosystems. The implementation of the "Millennium Ecological Assessment (MA)" project divides ecosystem services into four categories....
