摘要:
次生演替已成为川西亚高山针叶林迹地上的主要演替方式之一，然而鲜有研究针对该区域演替环境下土壤物理性质以及持水性能。我们选择了川西米亚罗林区现有次生然演替序列草地、灌丛、次生桦木林、原始针叶林为对象，以期能够揭示川西亚高山森林采伐迹地次生演替过程中土壤物理性质以及持水性能的变化规律。结果显示，草地、灌丛和次生桦木林与原始针叶林相比，土壤容重差异性显著，分别增加了52.17%、44.93%、17.39%，土壤总孔隙度和非毛管孔隙度差异性显著，分别减少了13.61%、11.60%、4.66%和14.44%、12.62%、 0.52% ；关于土壤持水性能，原始针叶林有着最高的土壤最大持水量和土壤非毛管持水量，分别为2315.44t/hm2和751.40t/hm2，随着次生演替进行，土壤非毛管持水量显著增加，细根和土壤有机质是导致土壤持水量变化的原因之一。这些结果说明，相对于原始针叶林而言，其它3种演替阶段的土壤蓄水能力都遭到了不同程度的破坏。前期采伐破坏了土壤物理结构，土壤仍留有“记忆”， 叠加上后期干扰，改变了土壤物理性质，使其具有较高的土壤容重和较低的土壤总孔隙度，因而土壤持水性能相对较差。这些结果对于人为加快川西亚高山针叶林迹地生态功能恢复措施的提出具有一定的理论与实践意义。（图3表3参5）
Abstract:
The secondary succession of subalpine forest in western Sichuan has become one of the main succession modes in this region. However, few studies have focused on the physical properties and water retention of soil under the succession environment in this region. Grasslands, shrublands, secondary birch forests and primitive coniferous forests in Miyaro forest area of western Sichuan were selected as the research objects, in order to reveal the change pattern of soil physical properties and soil water holding performance during the secondary succession. The results showed that the soil bulk density of grassland, shrubland and secondary birch forest increased significantly by 52.17%, 44.93% and 17.39% compared with the primitive con iferous forest, and the total soil porosity and non-capillary porosity decreased significantly by 13.61%, 11.60%, 4.66% and 14.44% , 12.62%, 0.52%. In terms of soil water holding capacity, the primitive coniferous forest stage had the highest soil maximum water holding capacity and non-capillary water holding capacity, which were 2315.44t/hm2 and 751.40t/hm2, the soil non -capillary water holding capacity of soil increased significantly with the secondary succession, fine roots and soil organic matter are one of the reasons for the change of soil water holding capacity . These results revealed that compared with the primitive coniferous forest, the soil water storage capacity of the other three succession stages has been damaged to varying degr ees. Early logging destroyed the physical structure of soil, and the soil “memory” was super posed with the disturbance, which changed the physical properties of soil and made it have higher soil bulk density and lower soil total porosity, therefore, the soil water holding capacity is relatively poor. These results have a certain theoretical and practical significance for accelerating the restoration of ecological function of subalpine coniferous forest in western Sichuan.
