摘要
在中国，确定山脉边界的标准有两种。一个是中国的国内标准(DC);二是国际标准(IC)。根据DC，有4 000 265平方公里的山区;而根据国际生态系统，山区面积为4 426 130平方公里。山脉分为6类:C1.300~1 000 m, C2.1 000~1 500 m, C3.1 500~2 500 m, C4.2 500~3 500 m, C5.3 500~4 500 m, C6。≥4 500m。在3 500 m以上的两个标准中，山的面积相等(C5和C6)。除DC中C1面积大于国际标准(324 508 km2)外，IC中C2、C3和C4面积均大于DC(分别为2 273 km2、336 186 km2和133 432 km2)。
The quantification of mountains in China Based on Geographic Information System
Two criteria are chosen to determine the boundaries of mountains in China. One is the domestic criterion (DC) in China; the other is an international criterion (IC). According to the DC, there are 4 000 265 km2 mountain areas; while according to the IC, there are 4 426 130 km2 mountain areas. The mountains are classified into six categories: C1.300～1 000 m;C2.1 000～1 500 m;C3.1 500～2 500 m;C4.2 500～3 500 m;C5.3 500～4 500 m;C6.≥4 500 m. The areas of mountains in the two criteria over 3 500 m are equal (C5 & C6). Except the area of C1 in DC is larger than international criterion (the value is 324 508 km2), the areas of C2, C3 and C4 in IC are larger than DC (the values are 2 273 km2, 336 186 km2 and 133 432 km2, separately).
