Guiding Knowledge2： About Tree Planting Day How does it come into being?(中国植树节的由来) -----孙中山先生，中华民国、国民党的创始人，被尊称为国父。他生前十分重视林业建设，1915年7月，在孙中山先生的倡议下，当时的北洋政府规定每年清明节为植树节，自此我国有了植树节。  1925年3月12日，孙中山先生逝世，为了纪念孙中山先生，把每年的3月12日定为植树节。 -----由于我国幅员辽阔，气候条件差异较大，所以各地适合植树的时间也不一致，许多省市便规定了自己的植树日。 美国植树节 Arbor Day （美）04：04 diary n. 日记keep a diary 记日记 Tree Planting Day 植树节3.12 hole n. 洞，孔；洞穴，穴；突
