The surface heating fields over QXP die down when sunspot cycle length(SCL) become long(the sun activity die down).

太阳黑子周期长度（SCL）变长（太阳活动减弱）时，青藏高原地面加热场强度减弱。

So, the Chinese civilization is related not only with the Yangtze River and Yellow River, but also closely with the rapid uplift of the QXP.

因此，中华文明的形成不仅与长江、黄河等流域有关，而且与青藏高原的剧烈隆起有密切关系。

Through the primary analyzing, we think that the sun activity is to cause the one of the important reasons of surface heating field change over QXP.

通过初步分析认为，太阳活动是引起青藏高原地面加热场强度变化的重要原因之一。
