    Design and implementation of land and sea coordinated “double evaluation” decision support information system in coastal zone

    • The development of the coastal zone has caused a series of resource and environmental problems, the flexible and efficient “double evaluation” of the coastal zone has become an urgent need for government decision-making and professional research.This paper adheres to the evaluation principles of ecological priority, adapting measures to local conditions, and simplicity, based on multi-source heterogeneous data such as land resources, water resources, climate, environment, ecology, and disasters, adopts GDAL open source library and GIS information technology, according to the evaluation method in the Technical Guidelines for Evaluation of Resource and Environmental Carrying Capacity and Suitability Evaluation of Land Space Development, establishes a spatial analysis and calculation model, designs and implements a “double evaluation” system for coastal zones.The system uses the evaluation model to realize the superposition, calculation, evaluation, mapping of single-element and multi-element resource and environmental data, as well as the display of evaluation results at different scales.Taking the Tianjin-Hebei-Liaoning coastal zone as an example to carry out relevant evaluation, the results show that the evaluation results of the system are accurate, and the calculation efficiency is 3-5 times that of manual work.The system can provide technical support and scientific support for resource and environmental management and land space planning.
