- Abstract:
- Using the NAI (negative air ions) data from monitoring stations of Heilongjiang Province in 2016,the spatial distribution characteristics of NAI concentration in different feature types of Sanjiang Plain and the relationship with climatic factors were analyzed comparatively,and try to monitor and analyze the NAI concentration in medium and large scales.The results showed that there were significant differences in the distribution of NAI concentration among four feature types in Sanjiang Plain,NAI concentration were gradually diminishing from the natural environment to the artificial environment in overall performance,waters>forest,cultivated land>residential area concretely.There was a highly significant positive correlation between NAI concentration and fluidity of waters:fountains,waterfalls>rivers and other flowing waters>lakes and other still waters;community structure complexity was the key factor of NAI concentration in forest area;NAI concentration in paddy field was higher than that in cornfield;the concentration in sparsely populated area was higher than that in densely populated area,there was a gradual increase from the center of cities to the villages.There was a significant positive correlation between NAI concentration and relative humidity in Sanjiang Plain;and negative correlation with the temperature,but the sole significant was the concentration in waters;there was only a significant negative correlation between NAI concentration and altitude in residential area.And the results could be used as a reference for resource development and ecological assessment in Heilongjiang Province,monitoring and evaluation of regional agricultural environmental quality,the prediction and control of air pollution.
