Intensive sea use adjustment method and system for marine ranch

Abstract

The invention discloses an intensive sea use adjustment method and system for marine ranches. The method comprises the following steps: firstly, extracting principal components from an input index and an output index by adopting a principal component analysis method; secondly, performing standardization processing on the principal component value of the input index and the principal component value of the output index by using a maximum value standardization method to obtain a first parameter and a second parameter; based on the first parameter and the second parameter corresponding to each marine ranch, calculating an efficiency value of each marine ranch by adopting a DEA cross efficiency evaluation model; substituting the efficiency value of each marine ranch, a third parameter and a fourth parameter into a Tobit model, and performing estimation by adopting a maximum likelihood method to obtain a regression coefficient corresponding to each variable; and finally, based on the regression coefficient corresponding to each variable, adjusting the intensive sea usage level of each marine ranch, thereby improving the overall intensive performance of the sea usage of the marine ranches, and realizing reasonable planning and management of the sea usage of the marine industry construction.

Description

technical field [0001] The present invention relates to the technical field of sea management for marine industry construction, in particular to a method and system for adjusting sea for intensive sea use by marine pastures. Background technique [0002] In recent years, marine ranching has become a new growth point of the marine economy as a new form of business that has both fishery resource restoration and water ecological restoration. The Chinese government is actively promoting the rapid development of marine ranching. Regardless of the confirmed area of ​​a single ranch or the overall scale, marine ranching has become an important new type of sea use. Due to the large sea area and scale of marine ranching, the rapid development of marine ranching will inevitably "occupy" sea space, and blind construction will easily lead to extensive development of marine ranching, resulting in the occupation of sea use by other industries and waste of sea area resources. [0003] At ...

Problems solved by technology

In recent years, with the gradual improvement of the marine ranching monitoring system, the number of monitoring indicators has increased, and the monitoring data has become more and more complete and accurate. Sea, due to the increase in the number of indicators and the lack of scientific rationality due to the fact that the original method ignores the internal relationship between indicators, it is difficult to rationally plan and manage the sea used for marine industry construction.
