Subsurface flow type constructed wetland ecosystem service value evaluation method and system and terminal

Abstract

The invention discloses a subsurface flow type constructed wetland ecosystem service value evaluation method and system and a terminal. The method comprises the steps of: carrying out the classification of the functionality of a subsurface flow type constructed wetland system according to collected subsurface flow type constructed wetland remote sensing data, and obtaining a plurality of functionality categories; calculating the environmental economic value quantity of each functionality category based on a K-Means clustering algorithm; calculating the total value of the subsurface flow type constructed wetland and the economic benefit of the constructed wetland according to a condition value evaluation method based on the environmental economic value quantity of the functionality categories; and determining the membership degree and the weight value of each functionality category, and obtaining a comprehensive value evaluation result of the subsurface flow type constructed wetland system based on the membership degree and the weight value of each functionality category. According to the method, the ecosystem service function value of the subsurface flow type constructed wetland system can be accurately reflected, and a more accurate result can be obtained, so that the ecosystem service function of the subsurface flow type constructed wetland system can be more accurately displayed, and the protection consciousness of human beings on a natural ecosystem can be stimulated.

Description

technical field [0001] The present invention relates to the field of ecological data processing, in particular to a method, system and terminal for assessing the service value of an underflow constructed wetland ecosystem. Background technique [0002] Constructed wetland is a ground similar to swampland that is artificially built and controlled. It is a comprehensive ecosystem. It applies the principles of species symbiosis, material recycling and regeneration, and the principle of structure and function coordination in the ecosystem to promote the benignity of pollutants in wastewater. Under the premise of recycling, fully develop the production potential of resources, prevent environmental re-pollution, and obtain the best benefits of sewage treatment and resource utilization. Plants in constructed wetlands can also transport oxygen to water bodies, increase the activity of water bodies, and degrade harmful substances; Wetland can be divided into free surface constructed ...
