Among them the influence factor of the stock is mainly: Fund manager select stocks ability, investment style and ability to deal with the accident, national macroeconomy situation factor, the market value of stock usually have the direct influence to the fund net value; To bond part in the net value of the fund, interest rate and the investment ability of fund manager concerns the value level of this part of assets directly, because the securities regulator of our country has made the regulation to the proportion of the fund investment bond besides this, so, this proportion will restrict fund managers investment on the bond either, thus exercise an influence on some value of bond ; Besides stock and two bond, to another important component in the net value composition --The cash, we will all sum up its factor of exerting an influence for the mobile risk factor, namely the risk as a reasult of the exility of cash.

其中股票方面的影响因素主要是：基金经理的选股能力、投资风格和选时能力以及大盘走势与突发事件、国家宏观经济形势因素，股票市值通常受到这些因素的直接影响；对于基金净值中的债券部分来说，利率和基金经理的投资能力直接关系到这部分资产的价值高低，除此以外由于我国证券监管机构对基金投资债券的比例作了规定，因此，该比例也会制约基金经理在债券上的投资，从而对债券部分价值发生影响；除了股票和债券两部分以外，对于净值构成中的另一重要组成部分——现金，我们将对其产生影响的因素全部归纳为流动性风险因素，即由于现金的稀缺而导致的风险。

Mining area ecosystem is a big system with complex behavior, and its dynamic evolutions are impacted not only by inner natural gender but also by many artificial exploitation factors. These inner causes and external causes interplay, mutually restrict and interact to each other, after that it forms a complicated reticulation. The set of these influence factors give huge force to evolution of mining area ecosystem, and it will cause the ecosystem deterioration or keep healthy.

矿区生态系统是一个行为复杂的大系统，影响其动态演化的因素除了其内在的自然性外还有诸多的人为开发因素，这些内因外因互相影响，互相制约，互相作用，形成一个网状的复杂体系，这样的影响因素的集合将会对矿区生态系统的演变产生巨大的作用力，使得生态系统向着恶化或者继续保持健康的方向运动。

内容提要：本文对五本期刊1990年以来有关传媒经济的研究文章进行了整理和考察，分析了我国传媒经济学研究的现状，指出了当前传媒经济研究的不足之处：&两个落差、两个脱节&，即定性研究与定量研究的落差、宏观研究与微观研究的落差、理论与实践的脱节、经济学理论与传播学理论的脱节；造成不足的原因是：主观上忽视了国外传媒经济研究成果的本土化、忽视了传媒经济学的本体论研究，客观上存在着体制因素的制约、人文科学研究习惯的制约以及研究者自身素质的制约；本文对今后传媒经济学的研究提出了建议：建立传媒经济学研究的科学构架、建立适合本学科特点的研究方法、充分吸收经济学的理论成果等。

Results showed that variability coefficients of the boll number per plant were the biggest under different ecological environment.Correlative degree analysis indicated that boll weight was the leading factor restricting the boll number;lint index was one of the major factors that affected boll weight,lint percentage and seed index;seed index was the primary factor restricting lint index.Results of path analysis sho...

结果表明，不同生态环境下单株成铃的变异系数最大；关联度分析表明，铃重是制约株铃的主导因素，衣指是制约铃重、衣分及子指的主导因素，子指是制约衣指的主导因素；通径分析结果表明，株铃对籽棉产量的综合直接作用最大；偏相关分析表明，单株成铃、单铃籽棉重、衣分3个产量因素性状对产量的贡献率占总决定度的77.16%，基本上反映了产量因素的构成情况。
