摘要:
 以林芝市7个功能区为研究对象，采用单因素方差和皮尔逊相关系数对空气负离子浓度状况进行研究，以期为市政规划提供参考，促进旅游业的发展。结果表明：1）除商业街外，其他生态功能区空气负离子浓度均为上午＜下午；水体、湿地日变化均为三峰型，空旷地、游憩绿地、商业街日动态呈双峰“M”型，林地、绿地日动态表现为单峰型。2）林芝各生态功能区浓度大小为水体（1 423个·cm-3）＞绿地（1 056个·cm-3）＞空旷地（1 039个·cm-3）＞林地（973个·cm-3）＞湿地（812个·cm-3）＞游憩绿地（723个·cm-3）＞商业街（717个·cm-3），平均浓度为943个·cm-3，水体旁空气负离子浓度是商业街的1.78倍。水体与其他6种生态功能区差异显著（P＜0.05），绿地、空旷地与湿地、游憩绿地、商业街差异显著（P＜0.05），其他功能区之间差异不显著（P＞0.05）。3）林芝各生态功能区空气质量指数（CI）大小为水体（1.143）＞绿地（1.133）＞林地（0.935）＞湿地（0.921）＞游憩绿地（0.891）＞空旷地（0.845）＞商业街（0.797）。4）空气负离子浓度与温度正相关而不显著（P＞0.05），与相对湿度负相关而不显著（P＞0.05）。林芝市空气负离子浓度较高、空气质量较好。
Abstract:
Taking the seven ecological functional areas in Linzhi as the research objects,the negative air ion concentrations (NAIC) were studied by one-way variance and Pearson correlation coefficient to provide reference for municipal planning and to promote the development of local tourism.The results showed that:1) except for the commercial area,NAICs of other ecological functional areas were all higher in the afternoon than in the morning; the daily variation of NAICs in water body and wetland presented 3-peak-pattern,and “M-tpye-pattern” in the areas of open space,recreational green space and commercial area.2) The order of NAIC in seven ecological functional areas was water body (1 423)>green space (1 056)>open space (1 039)>forest land (973)>wetland (812)> recreational green space (723)>commercial area (717 ions·cm-1),with an average concentration of 943 ions·cm-1,and NAIC near the water was 1.78 times higher than in the commercial area.The differences between the water body and the other six ecological functional areas were significant (P＜0.05).The differences between green space,open space and wetland,recreational green space and commercial street were significant (P＜0.05),and the differences between other ecological functional areas were not significant (P＞0.05).3) The order of air quality index (CI) of seven ecological functional areas was water body (1.143) >green space (1.133)>forest land (0.935)>wetland (0.921)>recreational green space (0.891)>open space (0.845)> commercial area (0.797).4) NAIC was positively correlated with temperature but not significant (P＞0.05),and negatively correlated with relative humidity but not significant (P＞0.05).It was concluded that the concentration of negative air ions in Linzhi City was higher,the air quality was better.
