Genetic diversity analysis within and between the green peafowl and the blue peafowl populations demonstrated that the expected heterozygosity of two peafowl populations were 0.2482 and 0.2744, respectively. The inbreeding index, Reynolds' genetic distance and gene flow between the two populations were 0.078, 0.0603 and 3.896 respectively. These results indicate that the heterozygosity and the genetic diversity of these two peafowl populations were very low, and suggest a tendency towards intermixing.

5与不同纬度的植物群落的比较结果表明：群落物种多样性和群落乔木层多样性指数随纬度的变化规律符合Wlater和Whittaker关于Shannon－Wiener指数随着纬度的升高而降低的结论，即与群落物种多样性的纬度趋势一致。

In the case of keeping individual diversity and improving the level of adaptability of the individual diversity in the population,the immune genetic algorithm based on selection probability of similarity and vector distance is proposed.

为了防止基于相似性矢量距为选择概率的免疫遗传算法在优化过程中出现退化现象，通过在算法中引入免疫疫苗的方式，对该算法进一步加以改进。

The construction of internal risk management system with the core of customer management system is the most innovative ideas the paper brings. For example, it presents pyramidal customer theory dividing customers into target customer, company customer, intent customer, trade customer and partner customer; in concrete risk management, it presents implementing diversity management according to customers' different level, different traits and different influential abilities with the aim to extend management scope to target customer onwards and transfer from trade customer to partner customer rearwards. This system is established in reducing and eliminating risk through diversity management towards customers. As corresponding measure going with this system construction, it presents new ideas of standardizing risk management flow and internal control process with ISO9000 system and implementing continuous improvement of risk management system through "6SIGMA" method.

以客户管理体系为核心的内部风险管理机制的建设，是本论文有创新点之处：金字塔型客户理论的提出，将客户分成目标客户、交往客户、意向客户、交易客户、伙伴客户；在具体的风险管理上，提出应根据客户的不同层次、特性和影响度实施差异化管理，将管理范围向前延伸到目标客户，向后扩展到交易客户向伙伴客户的培养转化；该机制立足于通过对客户的差异化管理来降低、化解风险，作为该机制建设的配套措施，提出通过ISO9000体系规范风险管理流程和内部控制程序，以及通过"6SIGMA"体系进行风险管理机制的持续完善的新见解。

The protection of cultural trade in the objective of safeguarding the world's cultural diversity, cultural diversity arising from the conflict as a natural barriers to the country's trade structure and trade gains will certainly have an impact, the article will adopt this model Ricardian trade analysis and verification.

文化贸易的保护在客观上维护了世界文化的多元性，多元化引起的文化冲突成为一道天然的贸易壁垒，对国家的贸易结构和贸易收益都会产生一定的影响，文章将通过李嘉图贸易模型对此加以分析和论证。

The results showed that the average heterozygosity was higher in 9 populations,the lowest is Jinding, the highest is San sheldrake, which ranged from 0.5137~0.6055. The average heterozygosity of 9 duck populations was 0.5523, which reflected the rich diversity. Considerable breed differentiation was observed and 25.65% of the total genetic variation came from breed differences, this result affirmed each breed was of own genetic diversity. The DA genetic distances suggested the longer differentiation existed between those breeds. The domestic duck breeds in East China were clustered into four groups based on the NJ clustering, the clustering results had some relationship with the distributions and economic utilizations of these duck breeds.

结果表明：9个品种的平均杂合度都较高，最低的为金定鸭，最高的为山麻鸭，杂合度范围为0.5137～0.6055，群体平均杂合度为0.5523，反映了各鸭种的杂合度都较高，遗传多样性丰富；华东区各鸭种间存在较大的遗传分化，25.65%的遗传变异来源于品种间的差异，更进一步反映了各品种具有本品种特征特性的多样性；通过计算DA遗传距离发现各群体的遗传距离较远，分化时间较长；NJ聚类结果将华东区家鸭资源聚为4类，NJ的聚类结果分析与几个鸭品种的地域分布和经济用途有一定关系。

The main results are: construction of Tarim desert highway shelter-forest promoted soil microbial development, and with increase of plantation time of the shelter-forest, the quantity, fatty acid diversity index of soil microbe and diversity index of bacterial DNA segment enhanced notably. As to soil microbial community structure, bacteria are dominant population with amounting for over 80% of total soil microbe, and fungi is not more than 1% of total soil microbe, but soil microbial community structure was different among three soil layers. The conclusions from study methods of conventional culture, biological marker and molecule biology were almost identical, which illuminates that construction of Tarim desert highway made soil microbial activity enhance and so promote nutrient cycle and utilization of Tarim desert highway shelter-forest land.

结果表明，塔里木沙漠公路防护林的建设促进了风沙土土壤微生物的发育，随着防护林定植年限的增加，土壤微生物数量、脂肪酸和细菌DNA片段的多样性指数明显增大；土壤微生物区系组成中，细菌是优势类群，占微生物总数80%以上，而真菌很少，不到微生物总数1%，但在不同土层间有所差异；传统培养法与现代生物标记和分子生物学方法对塔里木沙漠公路防护林地土壤微生物多样性的研究结果基本一致，说明塔里木沙漠公路防护林的建设使林地土壤生物活性有所增强，有利于林地土壤养分循环与利用。
