新疆地区降水量与气温、海拔的空间关系分析

Spatial Relationship Analysis on Temperature,Altitude and Precipitation in Xinjiang Region

利用空间展开模型,以新疆地区年降水量、年均气温以及海拔高度为指标,选取1970s、1980s、1990s、2000s年53个气象观测站的数据,对新疆地区年降水量、年均气温和海拔高度的空间关系进行分析。通过模型中气温及海拔高度对降水量的影响系数分析,能够充分反映新疆地区气温及海拔高度与降水量之间关系的空间变化特征。结果表明:新疆地区气温、海拔对降水量的影响强度随着地理空间位置的变化而变化,关系呈现出显著的空间非平稳性。

Based on the annual precipitation, annual mean temperature and altitude in Xinjiang, the spatial relationships of annual precipitation, annual mean temperature and altitude were analyzed by using the data of 53 meteorological stations in 1970s, 1980s, 1990s and 2000s. Spatial distribution model is used to replace the spatial position of each observation point by the geography position function of each observation station, which can solve the spatial heterogeneity caused by the geographical characteristics of each site. The influence of temperature and altitude on the precipitation is analyzed, which can reflect the spatial variation of the relationship between the temperature, elevation and precipitation in Xinjiang. The results show that the intensity of the influence of temperature and elevation on the precipitation in Xinjiang varies with the change of geography spatial position, and the relationship shows significant spatial non-stationaritv.
