The results are consistent with the interpretation that positive intangible information tends to trigger institutional herding on the buy side.3. The securities Investment Funds act as momentum traders in bear market while as contrariant traders in bull market. Further analysis reveals that momentum trading by investment funds intensifies stock return momentum but stock price experiences a long-term reversal. It indicates return momentum results from mispricing instead of risk. The securities Investment Funds hamper market efficiency when they act as momentum traders.4 Both momentum trading and herding behavior intensify market anomalies and hamper market efficiency. However, momentum trading or herding behavior is the only one of the many aspects of the institutional investor.

第三，机构投资者的动量交易行为会加重了股票收益惯性，这一结论在分别控制股票规模、账面市值比因素后仍成立，并且机构投资者对股票的动量交易行为越强烈，股票收益的惯性也越明显，说明机构投资者具有影响股票价格的能力；进一步的分析表明，惯性利润在长期均实现反转，但反转的周期和程度受动量交易指标值的影响，股票动量交易程度越高，动量收益反转越强烈，反转周期越短，这表明机构投资者的动量交易行为使股价严重偏离其基础价值，在长期，股票价格不断调整逐渐靠近其基础价值，因此可以说，机构投资者对股票的动量交易行为会加重股票收益惯性和阻碍市场效率。

With a study of plant community succession on 5 stocking rates,herbage utilizational efficiency and risk-benefit balance,it is suggested the sustainable development should follow:(1)no degradational principle of rangeland,(2)the maximum herbage utilizational efficiency,(3)the risk-benefit balance,When stocking rate was no more than 2.67 sheep/hm2,the proportion of grasses and plant biodiversity index and evenness were increased based on Artemisia frigida and short-grass rangeland.

草地畜牧业可持续发展的三大生物经济原则为草场不退化原则、最大生物学效率原则和风险-利润权衡原则：(1)草场不退化原则。在冷蒿小禾草退化草原上，暖季期间1.33～2.67羊/hm\+2的放牧率下可使其发生恢复演替，禾草的比例增大，植物多样性指数和均匀度指数均有所提高，从而达到利用式改良的目的；相反，若继续重牧或过牧，放牧绵羊喜食的植物种类将进一步减少，植物多样性指数也有所降低。
