Problems solved by technology

However, in practice, it is often found that although the biomass data of this species of fish increases, it may cause other related effects in the marine ranch, such as the length of the food chain or the reduction of diversity. are not ideal
It can be seen that it is incomplete and inaccurate to evaluate the effect of marine ranching based solely on the quantitative change of a certain indicator

Abstract

The invention relates to evaluation of marine ranching. At present, when the effect of the marine ranch is evaluated, the effect of the marine ranch is generally evaluated only based on the number change of a certain index, so that an incomplete and inaccurate evaluation result can be caused. A method, device and system are provided for evaluating a marine ranch based on a plurality of metrics. The method comprises: carrying out resource investigation on the marine ranch before and after construction; constructing a food web matrix according to species composition conditions; counting data ofa plurality of indexes of each nutrition level; counting the relative change rate of each index before and after construction of the marine ranch by referring to the comparison area; carrying out mathematical analysis on the relative change rate of each index, and screening out key factors; and evaluating the marine ranch based on the key factor.

Description

technical field [0001] The present invention relates to evaluating marine ranches, and more specifically, to a method, device and system for evaluating marine ranches based on multiple indicators. Background technique [0002] Marine ranch is an artificial fishery based on the principles of marine ecology, using modern engineering technology, making full use of natural productivity, creating a healthy ecosystem in a certain sea area, and scientifically conserving and managing biological resources. To carry out the construction of marine ranching, one is to increase the output of certain economic species or the fish output of the entire sea area, so as to ensure the stable and continuous growth of aquatic resources. The second is to focus on protecting marine ecosystems while using marine resources to achieve sustainable ecological fisheries. [0003] At present, when evaluating the effect of marine ranching, it is mainly based on the field survey of the sea environment and ...
