摘要： 通过对人工林与其周围荒漠灌木群落生物量及其土壤的物理化学性质的变化分析,结果表明: ① 克拉玛依人工杨树林林下植被层和凋落物层生物量为5.87 t·hm-2,荒漠灌木群落生物量为0.74 t·hm-2,人工林明显高于其周围荒漠; ② 林地土壤养分在不同土壤层次中的含量较荒漠有不同程度的降低,容重增加,但土壤含水率有较大提高; ③ 人工林地土壤有机质含量偏低,表层土壤有机质较荒漠降低8.83%,但林地10~30 cm和30~50 cm层土壤分别增加20.74%和33.13%; ④ 林内各层土壤含水率与凋落物层生物量呈显著正相关,土壤养分与生物量相关性不大。

Abstract: This study investigated the biomasses and the soil physical-chemical properties of the poplar plantations and the desert shrubbery communities around the artificial forest in Karamay. The study came with the following conclusions. First, the biomass of the understory vegetation layer and the litter layer of the poplar plantations was 5.87 t·hm-2; the biomass of the desert shrubby communities around the plantations was 0.74 t·hm-2. The biomass of the plantations was significantly higher than the biomass of the desert shrubbery communities around the plantations. Second, soil nutrients in the different soil layers within the plantations were lower than the biomass in the relative soil layers in the desert while the soil bulk density increased and the soil moisture significantly increased. Third, the soil organic matter of the plantation was lower than that of the desert. The topsoil of the plantation decreased 8.83% compared with the desert. However, the soil organic matters of the plantation at the soil depths of 10-30 cm and 30-50 cm increased 20.74% and 33.13% respectively compared with the desert. Fourth, within the plantations, there was a significant and positive correlation between organic matter of the litter and the soil moisture of each soil layers but no correlation between the soil organic matter and the soil nutrients.
