- 摘要:
- 根据2016年黑龙江省空气负离子浓度监测数据，比较分析了三江平原不同地物类型下空气负离子浓度，并探讨了其浓度与气候条件关系，试图长期监测中大尺度空间负离子浓度水平。结果表明：三江平原4种地物类型空气负离子浓度分布差异显著，整体上从自然环境至人工环境逐渐递减，水域>林区、耕地>居民区。水域负离子浓度与流动性呈极显著正相关，喷泉、瀑布>江、河等流动水体>湖泊等静止水体；群落结构复杂度是林区空气负离子浓度关键因素；耕地内水田中空气负离子浓度高于旱田；居民区内人口稀疏区高于人口密集区，由城市中心向乡村逐渐增大。三江平原空气负离子浓度与相对湿度呈显著正相关；与气温呈负相关，仅水域内负离子浓度与气温相关性显著，其余地类相关性不显著；居民区空气负离子浓度与海拔呈极显著负相关，其余地类与海拔相关性不显著。研究结果可为黑龙江省资源开发、生态评估、农业环境质量监测评价以及大气污染预防控制等提供参考，为中大尺度负离子浓度研究提供借鉴。
- 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.
