中文摘要 | 经多年观测 ,川中丘陵区桤柏混交林不同部位土壤的水分年变化不大 ,坡顶的无明显规律 ,坡腰大致呈单峰型变化 ,与年降雨过程有一定的同步性。林地的不同土壤层次间 ,坡顶的土壤水分年变化基本一致 ,而坡腰的则较复杂。林地土壤水分年变化与年降雨过程 ,总体上无明显的定量关系 ,只是坡腰的显示出一定的峰型模型关系。林区小流域单位雨量的径流模数随年时增加 (森林生长 ) ,无减小趋势 ,即桤柏混交林的调蓄能力并未持续增长 |
英文摘要 | The field observation data showed that the annual change of soil moisture content of various slope locations for the forestry slightly varied, no obvious change regular was found for top slope location while peak model change was identified and consistent with the annual change of rainfall for middle slope location. For various soil layers of the forestry, the annual change curve of soil moisture was coincident for top slope location but different for middle slope location. By and large, no signi ficant quantitative relationship between the annual change of soil moisture content and annual rainfall process was observed, the relationship only for middle slope location, indicated a peak model. The runoff modulus of unit rainfall did not decline with the time (growth of the forestry), which indicated that the capacity of water storage modulation did not increase for the forestry. |
