| 摘 要： | 沙枣是我国新兴的能源树种,为了简单、方便、准确地估算其生物量,笔者以地径、冠幅、树高作为自变量,利用数理统计方法筛选出不同密度下地上生物量的最佳估测模型。结果表明：不同密度的沙枣能源林生物量估测中需要各易测因子适当组合才能获得最高的相关性,拟合出最为理想的回归模型。

| Abstract: | The Elaeagnus angustifolia L.is emerging energy tree in our country.For simple,convenient,accurate estimating its biomass,the ground diameter,crown,tree height are as independent variable in the experiment.The best estimation model of the different density ground biomass is screened by using the mathematical statistic method.The result indicated: The Elaeagnus angustifolia L.of different density needs suitable combination with the various surveys factor to obtain the highest relevance,and which simulates th... |
