摘要
本文采用以“冰川覆盖率”为首要指标的多指标综合分析,讨论了中国冰川的规模及分布。作为分析方法,又提出“有效冰川作用正差”概念,并对其特征及应用进行了尝试性探讨。上述研究表明,“有效冰川作用正差”与“冰川覆盖率”呈良好的指数相关,反应了冰川发育规模及分布的自然规律。
Glacier area in China reaches 58700km^2, which makes up about 16%
of world' s alpine glacier and 47% of asia' s. In western China, glaciers
unevenly distribute in mountain ranges. This paper introduces a few im-
portant indices to all- sidedly describe the glacier dimension and distribu-
tion in China, such as 'percentage of national glacier area', 'average area
of a glacier', and 'glacial coverage proportion'.
Another concept, 'positive difference of valid glaciation' (He), has
been advanced to quantitatively analyze distribution laws of glaciers. It
has exponential relationship with 'glacial coverage proportion' (Cg) :
Cg=0.0021e^(0.0019^He)
