对机械整地、人工整地方式下塞罕坝华北落叶松人工林林分生长、生物量及生产力进行了研究,结果表明:机械整地条件下,34a生林分生物量为166.94t/hm2,人工整地条件下,34a生林分生物量为155.08t/hm2,可见采用机械整地方式可以比人工整地方式提高林木生物量7.65%;不同整地方式下,华北落叶松各组分的含碳量差别较小,树干的含碳量大约45.00t/hm2,大约占总碳储量的50.00%;通过对不同整地方式下生产力的比较,得出采用机械整地方式可以比人工整地方式提高华北落叶松人工林平均生产力12.40%。
The growth, biomass and productivity of Larix principis-rupprechtii Mayr. Plantation under mechanical land preparation and man-made land preparation were studied. The results showed that under the condition of mechanical land preparation, the biomass of 34a stands was 166.94t / hm2, Under the conditions, the biomass of the stands of 34a was 155.08t / hm2, showing that 7.65% of the forest biomass could be increased by mechanical preparation than that of artificial land preparation. Under different land preparation methods, the carbon content of Larix principis- , The trunk carbon content of about 45.00t / hm2, accounting for about 50.00% of the total carbon storage; by comparing the productivity of different land preparation methods, concluded that the use of mechanical preparation of land preparation can be better than artificial land preparation Larix gmelinii plantation average Productivity 12.40%.
