有关林带小气候与产量,A.P康斯坦丁诺夫、田中贞雄、傅抱璞、李德毅等人都曾进行过大量的调查研究,这些工作在揭示林带小气候效应及其对产量影响方面起着积极作用。本文在对林带网格中的光、温、风、湿与产量进行大量观测的基础上,首先查明林网内小气候因子与产量的分布,进而采用回归分析,由电子计算机对林网内小气候因子与产量的相互关系,进行综合分析,得到了各气候因子与产量间的定量关系式,同时指示出这些气候因子中,哪个因子对产量影响最大,哪个因子影响最小,并找出了各不因子单位变化可能对产量的影响。从而为全面正确地评价农田林网的防护效能。经济效益,以及有目的地采取调节措施与规划设计提供依据。
For forest microclimate and yield, A.P Constantinov, Tanaka Zhenxiong, Fu Baopu, Li Deyi and others have carried out a large number of investigations and studies, these efforts reveal a microclimate effect in the forest belt and its impact on the yield play a positive role. Based on a large number of observations of light, temperature, wind, moisture and yield in the forest belt grid, the distribution of microclimate factors and yield in the forest web was first identified. Then by regression analysis, Factor and yield of the relationship between a comprehensive analysis of the climatic factors and the yield was quantitative relationship between the same time, indicating the climatic factors, which factors have the greatest impact on output, which factors have the least impact, and to identify each Impact of changes in factor units on yields. In order to comprehensively and correctly evaluate the protective effectiveness of farmland network. Economic benefits, and purposeful adjustment measures to provide the basis for planning and design.
