摘　　要：云南松杉类植物的种质优势居诸省(区)域之首,本土产6科25属96种为“植物王国”的丰富多样添彩,与云南的地理位置特殊、地质地貌变化多样相关联。重点研究该种质的地理分布:1)以生态地理的不同层面(水平面的、垂直高度的、网络交织的)上种属的分布和变迁规律,残遗保存的特点;2)注重松杉树木对本域优势的多种针叶林生态系统的营建和地理分布的森林学性质分析;3)在此基础上落实全部本土生的松杉类植物的种、属、科的具体分布、生长和保存状况,包括原生的或后发生的,古老的或残遗的,泛域的或窄域的、国家保护的珍稀古特树种。The germplasm superiority of conifers in Yunnan ranks first in all provinces(regions)of China.The diversity of 96 species belonging to 25 genera,6 families is the highlight of the‘kingdom of plants’,which is related to the special geography and diverse geological landforms in Yunnan.The geographical distribution of the germplasm was studied:1)Based on the distribution and change law of species at different levels of ecological geography(horizontal,vertical,network intertwined),as well as the characteristics of relict preservation;2)The forestry properties of conifers on the construction and geographical distribution of local dominant coniferous forest ecosystems are emphatically analyzed;3)The distribution,growth and preservation of the species,genera and families of all native conifers,including protophyte or new species,ancient or relict,pan-range or narrow-range,state-protected rare endemic species,are determined accordingly.
