郑万钧先生与树木学

Professor Cheng Wan-chun and Dendrology

著名树木学家、林学家和林业教育家郑万钧(1904—1983),一生追求树木学科学与教育事业。作为树木学学习者,他勤奋好学,幸遇良师,治学有方;作为树木科学家,他专攻树木分类研究,主攻裸子植物分类研究,并从树木学拓展到森林地理学;作为树木学教育者,他主张立德树人,强调实践能力培养,注重科研反哺教学。郑万钧先生将林区看作最好的实验室,并亲临浙江西天目山、四川西部和湖北利川等林区实地考察,采集了包括模式标本在内的大量植物标本。郑万钧先生对树木学作出了许多贡献,发现并命名1个新科、5个新属和139个新种(含变种),其中最重要的贡献是发现并命名水杉(Metasequoia glyptostroboides Hu et W.C.Cheng)和建立裸子植物分类系统。

As a distinguished dendrologist,forester,and forestry educator,Professor Cheng Wan-chun(1904-1983)devoted his life to the pursuit of dendrology science and education.As a learner of dendrology,he was diligent and eager to learn,lucky to meet good tutors,and had a well-rounded approach to his studies.As a dendrologist,he specialized in tree classification,focusing on gymnosperms,and expanding his academic boundaries from dendrology to forest geography.As a teacher of dendrology,he advocated cultivating virtue and talent,emphasized the cultivation of practical abilities,and implemented the feedback of scientific research in teaching.Professor Cheng Wan-chun regarded forest areas as the best laboratory of dendrology and personally visited forest areas such as West Tianmu Mountain in Zhejiang,Western Sichuan,and Lichuan in Hubei,collecting a large number of plant specimens,including types.Professor Cheng Wan-chun made many contributions to dendrology,discovering and naming one new family,five new genera,and 139 new species(including varieties).The most important contribution was the discovery of Metasequoia and the proposal of a classification system for gymnosperms.
