AbstractThis study monitored thenegative ion concentrations in the Wudalianchi Scenic Area of Heilongjiang Province from 2018toO22 usinganegativeiondtector，anditsdiurnal，monthlyandseasonalvariatio paters were analyzed.Theresults indicatedthatthediurnalvariation of negative ion concentration in thestudy area followed a “U"-shapedpatern，withhigherlevelsinthe morningandafternoonandlowerlevelsatnoon.Interms ofmonthlyvariation， theconcentrationwas higherfromJulyto AugustandlowerinJanuary.Seasonaly，higherconcentrations wereobservedin summerandautumn，folowedbyspring，whilewintershowedrelativelylowernegativeionlevels.Thesefluctuations maybe related to environmental factorssuchas temperature，humidity，thunderstormactivity，andplant growthconditions.This study providesareferenceforthescientificutilizationofnegativeionandthedevelopmentofecotourismresources.
