摘要： 为了确定隔离布防护转基因水稻基因漂流效果，设计了隔离布防护措施的田间试验，利用试验观测资料，根据隔离布防护区的风速分布特征，建立迎、背风防护区风速分布模式，并通过实测资料检验模式的适用性。结果表明：经检验效果较好。背风面各模式的相关系数均在0.95以上，但是模型系数a因观测高度和风向角的不同而存在着一定差异；迎风面模式模拟值与实测值之间的相对误差平均小于10%。但是，本研究所建模式具有局限性，适用范围非常有限。

Abstract: In order to determine the isolation protective effect of genetically modified (gm) rice genetic drift, the field trials of the isolation protective measures had been designed. According to the experimental data and the characteristics of the windspeed distribution in protective isolation area, the speed distribution pattern of windward and leeward in protection zone had been established and the applicability of the model had been tested by the measured data. The results showed that: correlation coefficients of leeward side in each model were above 0.95. But because of different observation height and direction angle, there was a certain difference in model coefficient. The average relative error between simulated values and measured values in windward side mode was less than 10%. However, the model built in this research had limitations, and the scope of application was very limited.
