| 摘 要： | 本文以国内外农田防护林的大量观测资料为基础,划分了农作物在防护林保护下产量田间分布的主要类型,并借助计算机进行定量分析,提出且验证了相应的数学模型(FNC-I～FNC-Ⅳ),经F检验,有85.7％的实例超过了O.05的显著水平。最后从作物总产计算、对照点模拟、带距优化三方面简介了模型的应用。

| Abstract: | Based on the mass observation data of shelter forests on farmland both at home and abroad, the main types of feild distribution of crop yeild under protection of shelter forest were classified in this paper ; and the data were analysed quantitatively with computer, Then a relevant mathmatical model was put forward and verified, Through F- test, 85.7% real cases showed significant differences at 0.05 level .Finally, the applications of the model in total crop yeild calculation, in contrast plot simulation, and in belt distance optimization were briefly described. |
