落葉松落葉松Larix；larch松科落葉松屬植物的通稱。樹皮多呈厚片狀或長片狀剝裂。枝分長枝和短枝。葉螺旋狀散生于長枝，簇生于短枝，線形，扁平，柔軟，淡綠色，表面平或中脈隆起，背面中脈隆起，兩側有氣孔線。雌雄同株，花單性，單生于短枝上；雄球花黃色；雌球花近球形，苞鱗顯著，綠紫色或紅色，春季與葉同時開放。球果當年成熟，近球形，或圓柱形，苞鱗露出或不露出。種子形小，具膜質長翅，當年成熟時散落。喜光不耐頂部庇蔭。耐寒性強。需要濕潤而通氣良好的土壤。全屬約18種；分布于亞洲、歐洲和北美洲的溫帶高山與寒溫帶、寒帶地區。中國約有10種，分布于黑龍江、吉林、遼寧、河北、山西、陜西、四川、云南、西藏、新疆等地，其主要樹種有興安落葉松、長白落葉松、華北落葉松、新疆落葉松、太白落葉松、紅杉。華北落葉松興安落葉松通常用植苗造林。主要病害有落葉松枯梢病、落葉松早期落葉病、落葉松癌瘤病、心材蜂窩白腐和落葉松苗期立枯病。落葉松毛蟲和舞毒蛾，是最嚴重的食葉害蟲。此外還有落葉松球蚜、落葉松紅腹葉蜂和落葉松腮扁葉蜂等。落葉松木材堅實，不易腐朽，抗壓、抗彎性強。可做枕木、橋梁和車輛等用材。興安落葉松樹皮含單寧8.6％～16％，新疆落葉松含單寧4.6％～12.5％，是提煉栲膠的重要原料。落葉松樹冠規整、美觀，針葉柔軟，春季呈淡綠色，夏季呈深綠色，秋季呈金黃色，為城鄉綠化的優良樹種。
