在整个沉积物柱的孢粉组合中，松、杉等大型乔木始终占有很高的比例，而且越到上部比例越大，这除了受滇中地区气候地理因素的影响外，可能还有人为的原因，人们在保护森林资源和植树造林过程中往往只是注重了大型的乔木而忽视了灌木和草本植物，从而使森林生态失衡，生态效益低下。

The research progress in genetic linkage map construction of forest tree species both at home and abroad were reviewed in the paper.Two main problems involved in the field were discussed.One was the limitation of the number of individuals of mapping populations and the other was the random markers mostly employed by the majority of studies.These problems have resulted in crossing combination specificity in the constructed maps and the QTLs located on the basis of the maps.As a result,the QTLs discovered up to now have low credibility and poor practicability in marker-assisted selection.

本文就目前国内外林木连锁遗传图谱领域的研究进展进行了综述，指出了该领域研究中存在的主要问题，即一方面是作图个体的数量有限，另一方面是采用的标记以随机标记为主，导致了建成的图谱以及利用图谱获得的数量性状基因位点信息具有杂交组合特异性，造成了QTLs的可信度和在林木遗传改良以及标记辅助选择中的实用性降低等现象。
