摘要: |
[目的]探讨简单、方便且能准确估算盐沼植物生物量的方法,简化其生物量测定工作。[方法]以高度(H)和密度(D)2个形态因子作为变量,用数理统计方法构建茳芏(Cyperus malaccensis Lam.)生物量估测模型。[结果]茳芏地上生物量(Wa)以DH为变量进行估测更恰当,以DH为自变量的乘幂曲线模型Wa=0.0097(DH)1.177为生物量最佳估测模型。[结论]运用回归模型估算茳芏地上生物量可行,并可取得较为可靠的预测精度,茳芏地下生物量不能得出合适的估算方程。 |

Abstract: |
[Objective] The objective of the study is to find a simple and convenient method for estimating the accurate biomass of Cyperus malaccensis Lam., and simplify the measurement of the plant's biomass.[Methods] Statistics methods were used to construct the models using canopy plant height (H) and density (D) as variables.[Results] The results showed the above ground biomass(Wa) was accurate using DH as variable, and the best estimate model for above ground biomass of C.malaccensis is Wa=0.0097(DH)1.177.[Conclusion] Above ground biomass estimation of C.malaccensis by using the estimate model is feasible and relatively high precise,but estimation model for estimating below ground biomass could not be constructed. |
