Abstract

The invention discloses a method for comprehensively evaluating an ecosystem service of an artificial wetland. The method comprises the following steps of: A, establishing a target, evaluation criteria and an evaluation index of each criterion; B, establishing a scoring questionnaire of a step analysis judgment matrix for the comprehensive evaluation of the ecosystem service of the artificial wetland to form a criterion layer and an index layer; C, calculating a relative importance weight of the criterion layer relative to a target layer and a relative importance weight of the index layer relative to the criterion layer; D, calculating importance weights of a lowest layer and a highest layer and inspecting a calculation result; E, tracking and monitoring the characteristic of each index of the index layer and evaluating an original numerical value of each index; and F, multiplying the importance weight of general ranking in the step D by the fuzzy membership of the index obtained by the step E to obtain the comprehensive evaluation index situation of the ecosystem service of the artificial wetland. The method can conveniently, deeply and fully analyze all values of the ecosystem service of the artificial wetland. Guidance and basis are provided for design, optimization, construction, operation and management.

Description

technical field [0001] The invention belongs to the technical field of comprehensive evaluation of ecosystem services of constructed wetlands, and more specifically relates to a method for comprehensive evaluation of ecosystem services of constructed wetlands, which is applicable to the comprehensive evaluation of ecosystem services of most constructed wetlands. Background technique [0002] Humans have always depended on ecosystems for benefits such as clean water, food, suitable climate, fertile soil, nutrient cycling, and waste disposal. In the past, they have had many different definitions, but more recently they have been called "Ecosystem Services (ES)" and have gained worldwide attention. Access to these ecosystem services has also been taken for granted because they are often free, despite their vital role and significant economic value to humans. In fact, as the world's population explodes, ecosystem services are being degraded, and ecosystems have even collapsed i...
