本文调查了不同林带结构的防风效应。应用数理统计的方法,随机抽取202个数据,建立一个林带结构防风效应的数学模式, 即:Y=0.19094α+27.53397T+1.36578L+1.84616V-18.89249,以综合分析的手段,探讨林带结构因子与防风效应的内在关系。同时,也进行了调节林带结构与防风效应关系的研究。结果表明,林网内的防风效应主要取决于林带的疏透度,与林带树种防风特性指标、林带宽度、风速和风向也有密切关系;人工调节林带结构的措施在农业生产上具有重大意义。
This paper investigates the windbreak effect of different forest belt structures. Applying the method of mathematical statistics, we randomly selected 202 data to establish a mathematical model of windbreak effect of forest structure, ie Y = 0.19094α + 27.53397T + 1.36578L + 1.84616V-18.89249. By means of comprehensive analysis, And the windbreak effect of the internal relationship. At the same time, we also carried out a study on the relationship between the regulation of shelterbelts and the windbreak effect. The results showed that the windbreak effect in the forest network mainly depends on the permeability of the forest belt. It is also closely related to the windbreak characteristics, forest belt width, wind speed and wind direction of the forest belt. The measures of artificial adjustment of the forest belt structure are of great significance in agricultural production.
