摘要
根据中国暖温带森林植物习性，修订了Ｒａｕｎｋｉｅａｒ的生活型分类系统。通过对暖温带森林植物生活型谱的分析，证明暖温带森林群落植物生活型谱以地面芽为主，其次是地下芽。受水、热不足和人为活动频繁等条件的限制，暖温带地区缺乏或极少有高于２５ｍ的大高位芽植物；中高位芽、小高位芽和矮高位芽植物所占的比重与地面芽植物近似，其中落叶阔叶高位芽植物占有绝对的优势。主要由上述生活型所构成的暖温带森林植物生活型谱，基本反映了我国暖温带森林区夏季温暖多雨、冬季寒冷干旱的中纬度气候特征。
The Raunkiear's plant lifeform system was revised, according to the features of the forest plants in the warmtemperate zone of China, and based on the revised system, the lifeform spectrum analysis has shown that the hemicryptophytes are the dominant lifeform, accounted for 33.9% of all the forest vascular plants, followed by the geocryptophytes, which cover 19.7%, and all of the phanerophytes make up 27.5%. There are only few macrophanerophytes, being higher than 25 m, because of human activties as well as the inadequate water and temperature supply in this area. The general spectrum of the warmtemperate zone of China could basically represent the characteristics of middle latitude climate that is rainy and warm in summer, and frigid and dry in winter.
