摘要: <正>根据农田林网内棉花受(强)热带风暴侵害的程度,应用近代回归分析方法,建立了棉花倒伏程度X与产量Y的数学模型:列举了模型中建模指标的选择效果,模型的生态学意义,实用价值及限制条件等,为测定风灾条件下农田林网的防护效果提供了经验公式和依据。

Abstract: According to the degree of damage done to cotton by tropical storms in regional protection zones the authors established a mathematical model of cotton lodging and yielding in contemPOrary regression as follows: The effect of model index selection, ecological significance and its practical application and limitation of use have also been listed in the Paper. All these provide formats and standards for testing protective effects of windbreak networks against wind storms.
