Title: Study on Decision Rule Optimization and Organization of Group Decision-making Abstract Group decision-making, as one of the basic forms of decision-making, plays an important role in economic and political fields due to the ever-increasing complexity of decision issue and the enhanced democracy awareness. Research of group decision-making is receiving more and more attention as the cutting edge of decision-making theory. Fruitful results are achieved in this field, while there are still some weak aspects for further research, especially in the organization and decision process ot group decision-making. Researches in those fields are instrumental in optimizing the organization and decision process of group decision-making. And we have made some exploration in this paper as follows.

随着决策问题的日趋复杂化和人们民主意识的增强,群体决策作为决策的一种基本形式,在政治和经济生活中占有越来越重要的地位,而群体决策作为决策理论研究的热点和前沿也在国内外方兴未艾,并取得了丰硕的成果,但也存在一些薄弱环节和需要深入研究的问题,特别是在群体决策的组织结构和决策过程方面,如群体决策的规则优化、决策规则的约束性质、群体决策中领导的影响、决策者之间的相关性对决策质量的影响、序贯群体决策中各种组织因素对其决策质量、决策效率、决策收益的影响等等。

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 results indicate that the economic, ecological, social and comprehensive benefits of hedgerow intercropping are superior to that of traditional sloping cultivation. The comprehensive benefit of hedgerow intercropping of Leucaena leucocephala is better than that of Tephrosia candida. The results also indicate that application of superphosphate fertilizer for intercropping system improves crop yield and comprehensive benefits.

评价结果表明,植物篱种植模式的生态效益、经济效益、社会效益及综合效益均大于顺坡耕作模式,种植新银合欢植物篱比种植山毛豆植物篱的综合效益高;在种植相同植物篱树种的前提下,施磷肥比不施磷肥的效果好。

The results indicated that applying 105kg/hm2 nitrogen and 75kg/hm2 phosphorus fertilizer is the most economic and rational; applying 45000kg/hm2 farm manure with phosphorus as base fertilizer, two thirds nitrogen as seed manure and one third nitrogen as topdressing is more economic and rational;the best planting density is 67500 zhu/hm2, the transplanting style after growing seedlings in small arch greenhouse in early spring and the multiple cropping style after rape stubble should be extended over large areas, the multiple cropping style after wheat stubble should be extended in the southern rivers rigions of this locality.

在陇东旱作条件下,通过对&庆甜1号&进行肥效、密度及分期栽培等试验,正常条件下施N 105kg/hm2、P2O5 75kg/hm2是地膜覆盖种植&庆甜1号&经济合理的氮、磷施用量;45000 kg/hm2农家肥和磷肥一次性基施、氮肥的2/3作种肥,1/3作追肥施用较为经济合理;最佳种植密度为67500株/hm2;早春小拱棚育苗移栽和油菜茬复种两种种植模式宜在当地大面积推广,麦茬复种适宜在当地南部川道地区示范推广。

The industrial test for Lanping lead-zinc oxidation mine was carried out in this paper.The results showed that too low recovery rate of zinc was not induced by the flotation process of oxidation zinc mine,and the key point of solving the problem lied in how to reduce the produce rate of gangues and how to increase the recovery rate of the metals in gangues.The economic benefit of this process was also evaluated,the result showed that the economic benefit was obvious when the ores of Jiaya Mountain were trea...

对兰坪铅锌矿氧化矿进行了500t/d的工业试验研究,结果表明,氧化锌回收率较低的原因并非氧化锌浮选工艺的问题,如何降低矿泥的产率和能否回收矿泥中的金属将是解决兰坪难选氧化铅锌矿的关键所在,同时也对该工艺进行了经济效益评估,采用现行工艺处理架崖山工业矿具有一定的经济效益,在进一步完善现有工艺的基础上,具有一定的应用前景。

The main conclusions and outcomes are as follows:(1) From the coupling mechanism of economy and environment, the author appraises the degree of sustainable development in Jinlin province. The results show that the development orientation of Changchun is prone to economic development, for Jilin it is environmental development and for Liaoyuan it is harmoniums development at low level.
