为区域可持续发展提供科学依据。[方法
]
利用2014年2月25日上午9时和3月23日9时来自国家环保部的PM
2.5
时均浓度值
以GIS为平台利用双三次B样条方法
以中国陆疆国界为内插区域
模拟两个时相PM
2.5
浓度的空间分布
并在此基础上对比分析了中国和美国PM

浓度标准的差异
进一步分析荒漠化、降水、风速和经济增长水平对PM
2.5
浓度空间分异的影响。[结果
]
模拟结果表明
京、津为中心的华北地区是中国PM
2.5
污染严重的区域
珠三角是另一个污染较严重的区域
西藏、新疆和贵州等西部省区是中国PM

浓度与区域经济发展水平表现出显著的相关性。
[Objective] The characteristics of spatial distribution of PM2.5 in China and the influence factors were studied to provide scientific basis for environment monitoring. [Methods] This paper collected hourly concentrations of PM2.5 pollutant at 9:00 on February 25 th and 9:00 on March 23 th
2014. Consequentially
the countrywide spatial distribution of PM2.5 concentration was simulated within national boundaries using bicubic B-spline method in GIS. The concentration distribution was compared with that of USA spatially atdifferent standard. [Results] The most serious polluted region is Beijing and Tianjin-centered north China
and another is Pearl River Delta. The western provinces
including Tibet
Xinjiang and Guizhou area are good-air regions with low concentration. [Conclusion] There is a stable relationship between economic growth and PM2.5 concentration.
