摘  要:文章对库布齐沙漠中段沙柳、柠条锦鸡儿、中间锦鸡儿、小叶杨等4种典型人工林分的生物量和生产力进行了研究,研究过程中采用了标准木(丛)法和直接收获法对生物量和生产力进行了测定和计算,并对其进行了分析和比较。结果表明,林分生物量(整体、地上部分)两项指标排序一致:小叶杨(49 236.00kg·hm^(-2)、39 156.04kg·hm^(-2))>柠条锦鸡儿(26 225.70kg·hm^(-2)、18 473.20kg·hm^(-2))>沙柳(24 589.50kg·hm^(-2)、16 822.60kg·hm^(-2))>中间锦鸡儿(15 513.80kg·hm^(-2)、10 927.78kg·hm^(-2));地下部分生物量指标为:小叶杨(10 079.96kg·hm^(-2))>沙柳(7 766.90kg·hm^(-2))>柠条锦鸡儿(7 752.50kg·hm^(-2))>中间锦鸡儿(4 585.97kg·hm^(-2));林分净生产力(全部、地上部分)两项指标排序一致:沙柳(4 141.21kg·hm^(-2)·a-1、3 364.52kg·hm^(-2)·a-1)>中间锦鸡儿(2 491.29kg·hm^(-2)·a-1、2 185.56kg·hm^(-2)·a-1)>柠条锦鸡儿(2 105.74kg·hm^(-2)·a-1、1 847.32kg·hm^(-2)·a-1)>小叶杨(1 758.43kg·hm^(-2)·a-1、1398.43kg·hm^(-2)·a-1);地下部分净生产力:沙柳(776.69kg·hm^(-2)·a-1)>小叶杨(360.00kg·hm^(-2)·a-1)>中间锦鸡儿(305.73kg·hm^(-2)·a-1)>柠条锦鸡儿(258.42kg·hm^(-2)·a-1)。The biomass and productivity of four kinds of typical plantation (Salix cheilophila, Caragana korshinskii, Caragana intermedia and Populus simonii ) in middle part of Kubuqi Desert were studied. The biomass and productivity were not only measured and calculated by standard wood (cluster) method and direct harvest method, but also analyzed and compared. The result shows that the sequece of two indicators for stand hiomass (overall, aboveground parts) is eonsistante: Populus simonii (49 236.00 kg ·hm^-2,39 156.04 kg ·hm^-2) ; Caragana korshinskii (26 225.70 kg·hm^-2,18 473.20 kg·hm^-2) 〉 Salixcheilophila (24 589.50 kg·hm^-2.16 822.60 kg·hm^-2) 〉 Caragana intermedia (15 513.80 kg ·hm^-2,10 927.78 kg -hm-2 );the underground part of the biomass Index: Populus simonii (10 079.96 kg ·hm^-2 ) 〉 Salix cheilophila (7 766.90 kg ·hm^-2 )〉 Caragana korshinskii (7 752. 50 kg ·hm^-2〉 Caragana intermedia (4 585. 97 kg ·hm^-2); the net stand productivity (overall, aboveground parts) two indicators consistency the same.. Salix cheilophila (4 141.21 kg ·hm^-2·a^-1,3 364.52 kg·hm^-2·a^-1) 〉 Caraganainterrnedia (2 491.29 kg·hm^-2·a^-1,2 185.56 kg·hm^-2·a^-1) 〉 Caraganakorshinskii (2 105.74 kg·hm^-2·a^-1,1 847. 32 kg·hm^-2·a^-1) 〉 Populussimonii (t 758.43 kg·hm^-2·a^-1,1 398.43 kg·hm^-2·a^-1);the net productivity of underground part: Salix cheilophila (776.69 kg ·hm^-2·a^-1) 〉 Populus sirnonii (360.00 kg ·hm^-2·a^-1) 〉 Caragana intermedia (305.73 kg ·hm^-2·a^-1)〉 Caragana korshinskii (258.42 kg ·hm^-2·a^-1 ).
