Development of an aquaculture suitability assessment system of sea areas based on plug-in technology

To scientifically and rationally evaluate the suitable area for mariculture and optimize the structure and layout of the sea for aquaculture, this paper combines GIS software (ArcGIS) and the extension matter-element model, writes the script file of the extension matter-element model for evaluating suitability of the sea for aquaculture based on Python language, uses the C# language and the ArcObjects component development platform to create the ArcGIS Desktop Add-in plug-in, develops a system of sea suitability evaluation for aquaculture, and applies it to the coastal area of Liaoning province. The research shows that: (i) The scheme proposed in this paper integrates the functional characteristics of the extension matter-element model, which is suitable for multi-index evaluation, and ArcGIS spatial analysis through the “platform/plug-in” system architecture. It can provide a way to evaluate the suitability of sea for aquaculture in a rapid and accurate manner. (ii) The system evaluation results are in good agreement with the status quo. The system has strong applicability and universality, and can provide a reference for the selection of aquaculture sea area and the suitability evaluation in other fields.
