The genetic variation among the natural populations of ginkgo revealed by Nei"s analysis , Shannon"s information index analysis and analysis of Molecular Variance ISSR :Gst=0.1955,(= 0.1903,φST= 17.63%;RAPD:Gst=0.2882,= 0.2949,φST=36.69% was greater than other kinds of anemophilous plants. The genetic differentiation among populations might be caused by human selective pressures and barriers of geography.

3Neis遗传多样性分析、香农信息指数分析和AMOVA分析所揭示的银杏居群遗传分化水平ISSR ：Gst=0.1955，= 0.1903，φST= 17.63%；RAPD：Gst=0.2882，= 0.2949，φST=36.69%，高于一般风媒植物，可能是地理阻隔和人为选择造成的。

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。

The results of POPGENE analyze indicated that it was moderate level of the genetic diversity of Dipelta, mean PPB (percentage of polymorphic bands) h and I of 4 species of Dipelta as below: D.wenxianensis.(PPB=62.02%,h=0.1850,I=0.2826); D.yunnanensis (PPB=40.31%, h=0.1238, I=0.1874); D. floribunda (PPB=36.82%, h=0.1395,I=0.2045); D. elegans (PPB=15.51%, h=0.0583,I=0.0861). Genetic diversity in D.elegans is the lowest. It is possibly caused by the endemic distribution and local ecotope.

POPGENE分析结果表明，文县双盾木的多态位点百分率平均为62.02%，Nei&s基因多样性指数平均为0.1850，Shannon&s信息指数平均为0.2826；云南双盾木的PPB平均为40.31%；h值平均为0.1238；I值平均为0.1874；双盾木两个居群的PPB平均为36.82%；h值平均为0.1395；I值平均为0.2045；优美双盾木两个居群的PPB平均为15.51%，h值平均为0.0583；I值平均为0.0861；因此，我们认为双盾木属4个种的遗传多样性适中；而优美双盾木由于分布上的地理限制，居群的生境比较孤立，其遗传多样性较低。

An adaptive genetic algorithm in conjunction with multi-population genetic strategy, entropy-based searching technique with narrowing down space and the quasi-exact penalty function was developed to solve the optimization problem.
