临沧市膏桐种植区主要草本植物生物量模型研究

摘要

Taking planting area of Jatropha curcas in Lincang, Yunnan Province as study case, biomass models were established by using D (diameter) , H (height) and D2 H as variables and power function. Results showed that overall biomass model could be well expressed by using power function and the compound factor of D2H as variable was well to estimate biomass.%以云南省临沦市膏桐种植区草本植物为研究对象,分别以丛径(D)、丛高(H)及D2H作为自变量,利用幂函数方程拟合草本植物的生物量模型.结果表明,幂函数方程能较好地拟合地下部分及总生物量模型,用D2H复合因子拟合的效果较好.
