So must use information theory method depict and abundant the genetic diversity index system. in addition to, the introduce of molecule biology technology and the research of nucleotide sequence evolutive give a new method for population genetic, so must do deeply research about the analysis method of dna sequence data = the research main about the follows : there are three parts about the information model of population genetic : one about the shannon information entropy property of equilibrium population and the entropy change in the process of establish equilibrium ; another research is about the diversity measure - ment of genetic variation ; lastly, research the shannon information measurement about the disequilibrium gene variation. the result is : 1 to a definite gene distribution, the genotype entropy reach the maximum at the equilibrium population, the process of population from disequilibrium to equilibrium, the entropy get large and large

    此外,分子生物技術的介入及核苷酸序列進化的研究都為群體遺傳學的深入研究提供了新的途徑,但關于dna序列數據的分析方法需要作進一步的研究。本研究主要體現在以下幾個方面: (一)關于群體遺傳學的信息論模型研究,主要分為三部分內容:一是群體平衡的shannon信息熵的性質和群體平衡建立的熵變性質;二是群體遺傳多樣性測度的研究;三是非平衡群體的基因變異測量shannon信息量的方法研究。得到了如下結論: 1 、平衡群體的shannon信息熵最大,群體平衡的過程是熵的增大過程。
  4. So it was enlightened that t. jackii still had a high level of genetic diversity. the similar index between the t. jackii populations from jiangshi nature reserve and xufan reservoir was higher than that between the populations from jiangshi nature reserve and xufanggeng. it was determined by geographical factors

    聚類分析表明將石自然保護區的長葉榧居群與許坊水庫的相似系數較大,而和許坊埂的相似系數較小,這和地理上將石自然保護區和許坊水庫鄰近,而許坊埂距前兩者較遠的事實相符。
  5. Several results were concluded : firstly, the population of t. jackii was decreasing sharply and its living area was contracting, so the percentage of genetic variance among t. jackii populations was lower than that within its population ; secondly, its genetic diversity index was relatively high ; thirdly, according to its gene flow index, the population disintegration of the species could be prevented by genetic communication among populations of the species ; finally, the similar index between the populations from jiangshi nature reserve and from xufan reservoir was higher than that between the populations from jiangshi nature reserve and from xufanggeng, corresponding with the fact that it is nearer between jiangshi nature reserve and xufan reservoir than that between jiangshi nature reserve and xufanggeng

    2 、長葉榧的遺傳多樣性分析,分析了多態位點百分率( percentageofpolymorphicsites ) 、 nei氏基因多樣性指數( nei 』 sgenediversityindex ) 、 shannon信息指數( shannon 』 sinformationindex ) 、居群間的相似系數( geneticsimilarityindex )和遺傳距離( geneticdistance ) 、遺傳變異在居群間和居群內的分佈( thepercentageofvarianceamongandwithinpopulation )及基因流( geneflow ) 。結論是:分佈在群體間的遺傳變異較分佈在群體內的遺傳變異小,說明該生物的分佈范圍越來越狹小。
  6. A total of 145 rapd loci were obtained, of which 132 loci ( 91. 03 % ) were polymorphic. genetic diversity quantified by shannon index varied from 1. 50 to 2. 44 with an average of 1. 93 ; partition of genetic variability indicated that 69 % was distributed within, and 31 % among stocks
