AI Technical Summary

Technical Problem

Existing methods for investigating the terrestrial ecology of nuclear power plants cannot meet the requirements of the "Technical Guidelines for Environmental Impact Assessment: Environmental Impact Reports for Nuclear Power Plants," and the scope and content of the investigations are insufficient.

Method used

A field survey method for investigating terrestrial vegetation in nuclear power plants is provided, including surveying the site topography, setting up vegetation survey transects, surveying the terrestrial vegetation on site, processing data and estimating productivity. The method follows the principles of ecologically sensitive targets, prevailing wind direction, denser vegetation in the vicinity and sparser vegetation in the distance, and topography. Different quadrat sizes are used to survey grassland, shrubland and forest communities, and biomass is estimated using formulas.

Benefits of technology

It achieved the survey requirements of the "Technical Guidelines for Environmental Impact Assessment", provided basic data for the construction and operation of nuclear power plants, and clarified the survey methods for terrestrial ecological vegetation around nuclear power plants.
