落叶松属系统学研究概况

落叶松属系统学、分类学的研究在俄罗斯已有很长历史，基本可以划分为三个阶段，即１８￣１９世纪的落叶松属系统学研究的初始阶段。２０世纪初期落叶松属研究的发展阶段及现代落叶松属系统学的深入研究阶段。随着研究的深入，使落叶松系统学及这研究日趋完善，演化路线越见清晰，种及种下分类越趋合理。但由于研究者利用的研究手段不同。研究范围不同。所以还存在有一些有争议的地方，除此之外，这些争论也是由该种的生物学特性所决

A Survey on Systematics and Taxonomy of Genus Larix Mill.

It's very long history that the study of the systematics and taxonomy on genus larch (Larix Mill.) in Russia. Three stages of the study were divided including the initial stage of the study from 18 century to 19 century, the developing stage of the study in the early years of 20 century and the thorough study stage at present. With the deepening of the study. the systematics and the taxonomy of genus larch gradually tend to be perfected. the evolution line of larch tends to be cleared and the taxonomy of the species and subspecies tends to be reasonable. But the controversy about the systematics and taxonomy of larch is still present owing to the difference of the study method and the study range.using by different researchist. In addition. these controversies were caused by the biological characteristics of larch. because the insolating mechanism between species of larch is very less capable than other genera and many intermediate forms between species of larch were found. These intermediate forms brought difficulty to the systematic and taxonomic study of genus Larix.
