用来表示地球上水循环通常采用两种方法:一种是图解法;另一种是符号系列表解法。图解法就如高中地理课本《地球上的水》一章中所表示的“水循环示意图”那样。图解法形象直观地表示出手循环的基本特征:水循环的3个领域——海洋与陆地之间,陆地与陆地上空之间,陆地与海洋上空之间;水循环过程中的各个环节(降水、地表径流、入渗、地下径流、蒸发和植物蒸腾等)之间的关系。但图解法却不能提供用来研究水循环过程的合适结构,符号系列表解法可弥补这一缺
There are usually two methods used to represent the water cycle on Earth: one is a graphic method; the other is a symbol series representation. Graphical methods are like the “Schematic Water Cycle” in the chapter “Water on the Earth” in the high school geography textbook. The graphic image visually represents the basic characteristics of the hand cycle: the three areas of the water cycle - between the oceans and land, between the land and land, between the land and the oceans, and in the water cycle (rainfall, surface runoff The relationship between infiltration, underground runoff, evaporation and plant transpiration, etc.) However, the graphic method does not provide a suitable structure for studying the water cycle process. The symbol series solution can make up for this deficiency.
