获取了阿巴拉契亚流域245个地段(每地段面积≈1012平方米)的辐射干燥指数(β)和森林生物量(β是年净辐射总量与雨量潜热总量之比)。对β指数可作为复杂地形森林立地质量指标这一假设进行了试验。对流域平均森林生物量(M_0=15.94千克/平方米)、各地段生物量(M_i)、辐射干燥指数(β_i)和方位(A_i)进行回归分析,得到关系式: M_i/M_0=2β_i[1-A_i/2π+(A_i/2π)~4]±0.27方括号内表达式的值在A_i=0时(北坡)达到最大值,在A_i=227°时(西南坡)为其最小值。对于这一关系可作这样的解释;β表示各地段水——能交换对生长的影响(一定时期内),方括号内表达式表示地段小气候(与坡向相相关)的日波动对生长的影响。
Radiation dryness index (β) and forest biomass (β is the ratio of total annual net radiation to total rainfall latent heat) are obtained for 245 locations in the Appalachian Basin (≈1012 m2 per lot). The hypothesis that the β index can be used as a quality index for complex topographical sites is tested. The regression analysis of average forest biomass (M_0 = 15.94 kg / m2), biomass (M_i), radiation drying index (β_i) and azimuth (A_i) -A_i / 2π + (A_i / 2π) ~ 4] ± 0.27 The value of the square brackets reaches the maximum value at the north slope (A_i = 0) and the minimum at A_i = 227 ° (southwest slope). For this relationship can be interpreted as such; β said that the water - exchange of the various sections of the impact on growth (within a certain period of time), square brackets represent the microclimate (with slope phase correlation) of daily fluctuations in growth influences.
