应用SPSS分析降水年际年内变化对泉水动态影响—以济南明水泉域百脉泉群为例

Analysis of Precipitation Interannual and Intraannual Variability Impact on Spring Dynamic by Using SPSS Software —A case from Baimai spring groups of Mingshui spring area in Jinan

摘要:

该文以济南明水泉域百脉泉群为例，运用SPSS软件，采用皮尔逊（pearson）相关系数法，分析了大气降水年际变化、年内变化对泉水流量及水位的影响。分析表明：前一年降水及前二年降水量与泉水流量呈强相关关系，当年降水对泉水流量影响相对较小，呈中等相关关系；当年降水与前一年降水与泉水水位为强相关关系，前二年降水影响略小，为中等相关关系；泉水月流量与前2、3个月降水有较强的相关性，泉水水位则与前2个月大气降水具有中等相关性。丰水年及平水年泉流量、水位高峰值在时间上较降水的高峰值推迟1～3个月，泉水水位最大日升幅一般滞后某一次大的降水过程之后1～2天。

Abstract:

The article analysed precipitation interannual and intraannual variability impact on spring dynamic using Pearson correlation coefficient method, and statistic analysis software spss. Anlysis showed that: precipitation of previous year and previous 2 years had strong correlation with spring flow, but precipitation of same year had moderate correlation with spring flow. The precipitation of same year and previous year had strong correlation with spring water level, but precipitation of previous 2 years had moderate correlation with spring water level. Monthly spring flow had strong correlating with precipitation of previous 2 and 3 month, while spring water level had moderate correlation with precipitation of previous 2 month. Spring flow and water level usually lag behind the precipitation peak about 1 to 3 month. The maximum daily increase of spring water level usually lag behind the precipitation peak about 1 to 2 days.
