| 摘 要： | 本文研究了晋西北汕松人工林的生物量与营林前景。样地设在河曲县阴山林场范围内海拨1300米左右黄土丘陵沟壑区。应用W_S=118.623(D~2H)~(0.705),W_B=91.319(D~2H)~(0.691),W_L=122.037(D~3H)~(0.640)和Wr=131.447(D~2H)~(0.490)幂函数优化模型,分别获得了树干、枝条、叶子和根系的生物量。乔木层的生物量为11.338吨/公顷,幼树的生物量为0.294吨/公顷,草本层的生物量为0.180吨/公顷。油松林的总生物量为11.812吨/公顷。油松林乔木层的生物生产力明显高于当地杨树人工林,今后应提高油松在晋西北绿化树利’结构中所占的比重。

| Abstract: | This paper centers on the biomass and afforestation prospect of pine plantation in northwest Shanxi Province. The sample plots were located on Yinshan Mountain in Hequ County at an altitude of 1300m. By using power equations Ws = 118.623(D~2H)~(0.705), W_B=91,319(D~2H)~(0.691), W_L=122.037 (D~2H)~(0.640) and W_i=131.447(D~2H)~(0.490), the biomass of stems, branches, leaves and roots was obtained. The biomass of matured pine plantation was 11.338t/ha. The biomass of young trees was 0.264t/ha, and the biomass of the herbaceous layer was 0.180t/ha. The total biomass of the pine plantation was 11.812t/ha. The annual net production of tree layer of pine plantation was much more than that of ordinary poplar plantation at the same area. From now on the portion of pine plantation in the forestry construction of northwest Shanxi should be increased. |
