摘 要：
利用幂函数、多项式、指数函数三种理论模型,拟合榛树生物量估测模型,从中选择最优的生物量估测模型,利用毛榛木屑栽培黑木耳试验,分析毛榛林开发利用经济效益。研究结果显示:通过比较拟合统计量,最终确定幂函数W=0.0013D~(1.9102)H~(1.1524)和多项式w=-9.914 4+0.002 5(D~2H)-0.000 000 000 132(D~2H)~2是毛榛生物量最佳估测模型,以栽培黑木耳为例,9年生的毛榛林开发利用经济效益为57,146元/hm~2。

摘 要：
Using three theoretical models of power function, polynomial and exponential function, and the hazel biomass estimation model was fitted. The optimal biomass estimation model was selected. The black fungus was used to test the development and utilization of hazelnut forest Economic benefits. By comparing the fitted statistics, and the results showed that the power function W=0.0013 D~(1.9102)H~(1.1524) and the polynomial w=-9.914 4+0.002 5(D~2H)-0.000 000 000 132(D~2H)~2.The both are the best estimation models of hazelnut biomass. Taking the cultivation of black fungus as an example, the economic benefit of developing and utilizing 9-year-old hawthorn forest is 57,146 yuan/hm~2.
