思茅松研究现状的探讨

A REVIEW OF THE RESEARCH STATUS OF PINUS KESIYA VAR. LANGBIANENSIS IN SOUTHWESTERN CHINA

本文从区系地理、生物特性、生态特点和开发利用等方面对思茅松的研究现状和存在问题作了系统的总结。认为思茅松是个重要的森林树种、在起源及分布上都与云南松和卡西亚松有联系，从理论到生产实践，都需要开展深入细致的研究。

This paper is a general review of the research status of Pinus Kesiya var.Iangbianensis, which naturally occurs in southwestern China with a range of latitude 21°10′- 24°24′N and longitude 99°05′- 102°30′E.,to summarize the information materials on the taxonomy, floristic geography, biology and ecology, utilization and genetic conservation of the species.A conclusion could be drawn that P. Kesiya var. langbianensis was floristicaly not a substitute species of Pinus Yunnanensis being geographically replaced along ecological qradient. P. Kesiya var. langbianensis is an important tree species in the natural forest, and very closely related to P.Yunnanensis and P. Kesiya in terms of the origin and distribution,therefore, it is suggested that more research should be undertaken with its morphology,genetics and population ecology.
