摘  要:
马桑是甘肃成县丘陵区的重要薪炭树种,生长在不同立地条件的马桑林生物量差异甚大。在试验区内划分三个不同的立地质量级进行生物量及热能的估算。高、中、低三个立地质量级生物量的最适模型分别为B_(H)=66.8199(D~2H)~(0.9778),B_(M)=65.4861(D~2H)~(0.9531)和B_(L)=108.8330(D~2H)~(0.8375);生物量分别为8581.61公斤/公顷,7119.12公斤/公顷和2062.34公斤/公顷。一个占有2亩马桑林面积的5口之家每年可樵采马桑薪炭林干重789.47公斤,占总需要量的38.45%。

摘  要:
Chinese coriaria is an important fuelwood species in hilly land of south Gansu. Remarkable difference of biomass and calorific value were measured among three stands grown in different sites. According to the significant correlation of diameter at foot, tree height and dry weight of individual, the optimum models of high, medium, and low site quality classes are set up: B_((H))=66.8199(D~2H)~(0.9778) B_((M))=65.4861(D~2H)~(0.9531) B_((L))=108.8330(D~2H)~(0.8375) Estimates of biomass for three sample areas were 8581.61kg/ha, 7119.12kg/ha and 2062.34kg/ha, respectively. A family of five members with 0.13 ha of land could harvest fuelwood for 394.75kg(dry weight) each year, which accounts for 38.45% of the total requirement.
