据我国基础地理信息中心专家介绍,珠峰8848.13米受到国外质疑主要有三大原因。一是起算面也就是海拔原点的选择不同。据介绍,地球海平面也存在高低差别,以我国珠峰高程起算面黄海平面与印度洋海平面为例比较,两者就存在20厘米左右的差距。第二个原因是珠峰冰雪层的变化。据悉,目前珠峰高度均为珠峰冰雪层高。但随着季节变化,珠峰顶部的冰雪层厚度也会有1至2米的变化。这也意味着不同季节测量,所得的数据也会不同。第三个原因是测量精度。据介绍,目前已知的不同的测量方法,精度差别可达50厘米左右。
According to China’s basic geographic information center experts, Everest 8848.13 meters questioned by foreign countries there are three main reasons. First, the starting surface is the origin of altitude choice is different. According to reports, the earth’s sea level there is also high and low differences, with China’s Mount Everest elevation from the surface of the Yellow Sea and the Indian Ocean sea level as an example, the two exist about 20 cm gap. The second reason is the change of ice and snow in Mount Everest. It is reported that the current height of Mount Everest Everest snow layers. However, as the seasons change, the thickness of the ice sheet at the top of Mount Everest will vary by 1 to 2 meters. This also means that the measurements taken in different seasons, the data obtained will be different. The third reason is the measurement accuracy. According to reports, currently known different measurement methods, the accuracy of up to about 50 cm.
