The result of the PCPP was validated by the method of remote sensing. The relationship between the PCPP and NDVI was significant at to 0.01 level. The estimated results of Thornthwaite-Memorial model was better than the Miami model.

• 用遥感方法对 2种模型的估算结果进行了验证 ,模型估算结果与北京山区植被指数 (NDVI)的相关性均达到了 0 0 1的显著性水平 ,且桑斯维特纪念模型的估算结果好于迈阿密模型。
