图2 土壤湿度和蒸散发的相关系数（a）及耦合强度指数CSISM-ET（b,单位：mm·d-1）的多年平均值空间分布 [图2（b）中只给出图2（a）中相关系数为正且通过α=0.05显著性检验的格点的耦合强度的多年平均值]

Fig.2 The spatial distribution of annual average of correlation coefficient （a） and coupling strength index CSISM-ET（b, Unit： mm·d-1） between soil moisture and evapotranspiration （For each grid box, the coupling strength indexes in Fig.2（b） were shown only when the correlation coefficient between SM and ET in Fig.2（a） was positive and passed the test at the significance level of 0.05）
