Embodiment Construction
[0048] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0049] 1) Based on the Northwest Pacific squid fishery point and CPUE data from 2004 to 2013, from the recorded fishing data, the date, latitude and longitude, catch (CPUE), and puncture were taken as the research data. Calculate the CPUE by year of the obtained data, and draw the spatial distribution of CPUE as shown in figure 2 ;
[0050] 2) For the analysis of hot and cold spots in the fish catch (CPUE), calculate the Getis-OrdGi* statistics for each element in the data set, and calculate the z-score.
[0051] 3) Based on the z-score and SST, CHL-a data, establish a geographically weighted regression model, derive the GWR parameters C1 and C2 data related to the marine environment, and draw the contour maps of C1 and C2;
[0052] First obtain a properly specified OLS model, then run GWR with the same explanatory variables. Build the GW...
