Based on wetland resources evaluation theory, aiming at the characteristics and current situation of wetland in our country, this paper determined 9 indicators including the species abundance, species relative abundance, rare species, formation degrees, wetland type, protection land type, invasive species, vegetation damage, protection consciousness and management level, established wetland biodiversity evaluation system, also determined the scientific and accurate grading standard and weight. The results can provide reliable basis for the future evaluation, protection and restoration of wetland biodiversity in China.
