The results show that small world network model could explain the big change of intensiveness and connectedness in forming process. And individual selection value function could explain the stable intensiveness, connectedness in growing and mature process. Combined the both, the characteristics of the whole process could be reflected.

研究表明，小世界网络模型模拟的集群网络具有集群形成期网络整体密集性和连通性剧烈变化的特征，而个体选择价值函数模型可以解释集群网络的成长期、成熟期的密集性和连通性趋于稳定的特征，将2种演化规则相结合，则可以反映集群网络从形成期到成熟期的各生命周期特征。

A clone from each genotype was randomly selected as representative for sequencing. The obtained 16S rDNA gene sequences had a similarity of 87%-100% with those in the GenBank (www. ncbi. nlm. nih. gov), and more than half of them had a similarity lower than 97%, being of new species. Based on phylogenetic analysis, the bacteria in the two soils were classified into 10 groups, with 5 groups in common. The dominant bacterial groups in the two soils differed obviously. In primeval forest soil, the dominant group was Proteobacteria, which had 39 genotypes, occupying 58.0% of all the clones; while in the soil of degraded ecosystem the dominant groups were Acidobacteria and Proteobacteria, which had 19 and 15 genotypes occupying 32.5% and 30.5% of all the clones, respectively. In the soil of degraded ecosystem, Proteobacteria group decreased while Acidobacteria group increased markedly, compared with those in primeval forest soil.

The local decision space partitioning is given in the sense of maximum Bhattacharyya distance criterion. The optimality and the non-triviality of the partitioning scheme are proved. The reasonability of using Bhattacharyya distance as partitioning criterion is analyzed. The simulation results show that the partitioning method based on Bhattacharyya distance criterion is superior to that based on J-diversity criterion.

According to disadvantage of AS that the speed low of convergentiss and easily entering the stagnation,improving the AS in some aspect by the way that importing pheromone windows that the value of pheromone cannot exceed the window,only deposit the pheromone on the edge that belongs to the iteration shortest solution path,releasing additional pheromone to the edge belongs to the so-far shortest solution path,judging the situation of convergent and to reinitialize pheromone,optimizing the solutions by local search procedure at the end of every iteration,modifying the transition probability by add some problem specific parameters and so on.

本文主要运用蚁群优化算法(Ant Colony Optimization，ACO)来求解VRP。针对蚁群算法收敛性比较差，易于停滞的缺陷，通过使用信息素窗口限制、信息素的最大最小值，只更新信息素迭代中最好解，增加了精英的蚂蚁，信息素重新初始化之前先判断出汇聚情况，在每次迭代过程中加入局部的搜索进行优化，在对蚁群算法进行了优化时考虑选择概率当中加入与问题的相关参数等措施，从而使蚁群算法的收敛性得到大大提高，避免了算法的停滞现象。

Effectively integrated the mine physical natural environment information into the mine virtual environment, the MSNE model can enrich enormously the virtual environment knowledge and enhance its practicabilityThirdly, the modeling method of virtual human in MIVE was studied systematically and an intelligent virtual miner model was constructed. The intelligent miner has lifelike human appearance and possesses abroad ability of perception, motion, behavior, cognition and mental state. And a behavior control model based on the simpled consumption architecture was proposed to select, activate and terminate the basic reactive behavior for virtual miner. And some intelligent behaviors including vision perception, path planning and self-determining ramble also were studied. The intelligence and interaction of virtual environment are just embodied by the intelligent life, especially by the intelligent behaviors of virtual human.

The results above showed:(1) The cultivars of large-flowered chrysanthemum are widely distributed in Beijing area with plentiful floral types and floral colors;(2) The cultivars with the rare types and colors are urgent for protection;(3) Most of the quantitative characters obeys to the normal distribution,some important traits agreed with skewed distribution.The probability grading can assist quantitative character in establishing new grading standards;(4) Most of qualitative characters is asymmetrical in cultivars,which might be caused by unbalanced differentiation of characters or linkages coming from emphasis characters selection;(5) The floral characters are relatively stable and have comparably large influence on classification,the characters of stipule also have a certain degree of stability and can act as an reasonable supplement for cultivars classification,but the foliar characters have worse stability and can only be recognized as lower level criterion.(6) The genetic relationship among the Flat-petaled group,the Quilled-petal group and the Spoon-petaled group are closest,which followed by the Filiform-petal group because of long-term selection pressure for the specialization of the petal tip loved by most people.The Anemone-petal group has further genetic relationship with these four groups.(7) ISSR molecular marker detection indicates that the proportion of polymorphic loci of lardge-flowered chrysanthemum is higher,in which the Flat-petaled group has the highest genetic diversity level.

综合以上的研究结果表明：(1)北京地区现有大量大菊品种，且花型与花色较为丰富；(2)珍稀花型、花色品种亟需保护；(3)大部分数量性状是符合正态分布的，少数重点观赏性状迫于选择压力呈现偏态分布，概率分级法能够辅助大菊的数量性状建立新的分级标准；(4)大部分质量性状在品种群内的分布是不均匀的，可能是由菊花性状遗传分化的不均衡性或受到选育重点性状的连锁作用而造成的；(5)大菊花部性状相对稳定，对品种分类影响较大，其托叶部分也具有一定程度的稳定性，可以作为品种分类的合理补充，而叶部性状稳定性较差，在品种分类中应作为更次一级的分类依据；(6)平瓣类、管瓣类和匙瓣类的亲缘关系最近，畸瓣类品种花瓣先端特化受到人们的喜爱，长期的选择压力使其区别于3种基本瓣型，而这四种瓣型与桂瓣类在亲缘关系上较远；(7)ISSR分子标记检测表明：大菊品种多态性位点百分率较高，平瓣类品种的遗传分化最为丰富。
