摘  要:
选取74个甘肃省内各国家级气象地面站的观测结果(1981—2010年),采用空间自相关分析方法,选取纬度、经度、海拔、气温、降雨等要素,对各地面站点的全局空间自相关和局部空间自相关分布特征进行了分析。结果表明,甘肃省各气象站所选地理要素的空间自相关性显著程度从高到低依次为经度、纬度、降雨量、海拔和气温;异质性高的站点平均占比为22.2%,其余站点则表现出一定的聚集性;在气温和降雨2种要素中,HL型站点的平均占比为5.2%,而LH型站点的平均占比为19.4%。通过本研究,能够分析甘肃省内各国家级气象站观测数据之间的空间自相关性分布特征,对于省内气候条件现状及空间差异性规律分析具有重要意义,此外,还能够根据研究结果科学预判省内极端气候事件出现的类型,对于优化气象站布局和管理者科学决策具有一定的现实指导意义。

摘  要:
The observed results from 74 national meteorological stations in Gansu Province(1981—2010)were selected,and the spatial autocorrelation analysis method was used to analyze the global spatial autocorrelation and local spatial autocorrelation distribution characteristics of ground stations by selecting latitude,longitude,altitude,temperature,rainfall and other factors. The results showed that the significance of spatial autocorrelation from high to low was longitude,latitude,precipitation,altitude and air temperature,respectively. The average percentage of stations with high heterogeneity was 22.2%,the rest stations performed as the clustering. Among the air temperature and precipitation,the stations with HL type accounts for 5.2%,while the stations with LH type accounts for19.4%. Based on the research,the spatial distribution of data from the meteorological station in Gansu Province can be analyzed,which contributes to the research of climate condition and spatial difference in Gansu Province and can forecast the appearance of extreme climate event. This paper can provide the scientific basis for the layout of meteorological stations and decision of the administrators.
