【摘要】：目的比較不同的數(shù)據(jù)處理方法對于石河谷空氣質量定量評價結果以及森林環(huán)境條件下空氣質量等級劃分的影響,為后續(xù)研究提供最佳數(shù)據(jù)處理選擇方案。方法利用Origin9.0軟件,采用整體平均法和降維法分別對石河谷森林環(huán)境空氣離子濃度觀測結果進行統(tǒng)計分析,并對分析結果進行比較。結果整體平均法、時序降維法和降序降維法FCI計算結果非常接近,而且空氣質量清潔度和空氣質量分級結果是一致的。但是,升序降維法FCI計算結果普遍偏低,與其它3種數(shù)據(jù)處理方法相比較,13個觀測地點的FCI平均值,有12個與整體平均法、降序降維法和時序降維法對于空氣質量分級結果是一致的,僅有1個出現(xiàn)差異,即差異率為7.7%。而且方差分析結果顯示,4種不同的數(shù)據(jù)處理方法,對于森林環(huán)境下空氣質量評價指標FCI值的影響,不存在顯著差異。結論降序降維法和時序降維法都可以作為比較理想的森林環(huán)境下空氣正負離子濃度測定結果的處理方法,依據(jù)FCI平均值來定量評價森林環(huán)境的空氣質量;而且與整體平均法相比較,因為變量少,更便于進行統(tǒng)計分析。
[Abstract]:Objective to compare the effects of different data processing methods on the quantitative evaluation results of air quality and the classification of air quality in forest environment. To provide the best data processing options for further research. Methods Origin9.0 software was used. The global average method and dimensionality reduction method were used to analyze the observed results of air ion concentration in the forest environment of the stone valley, and the results were compared. The results of sequential dimensionality reduction method and reduced order dimension reduction method FCI are very close, and the results of air quality cleanliness are consistent with those of air quality classification. However, the results of ascending descending dimension method FCI are generally low. Compared with the other three data processing methods, 12 of the FCI mean values of the 13 observation sites are consistent with the global average method, the reduced dimension reduction method and the sequential dimensionality reduction method for air quality classification. There was only one difference, that is, the difference rate was 7.7. The results of variance analysis showed that four different data processing methods had an effect on the FCI value of air quality evaluation index in forest environment. Conclusion both sequential and sequential dimensionality reduction methods can be used to deal with the determination results of positive and negative air ion concentration in forest environment. The air quality of forest environment was evaluated quantitatively according to the average value of FCI. And compared with the global average method, because the variables are less, it is more convenient for statistical analysis.
