缙云山不同类型植被坡面土壤水分特征
- Title:
- The Soil Water Characteristics of Several Woodlands in Jinyun Mountain
- 分类号:
- S714
- 摘要:
- 研究了位于重庆市缙云山不同植被类型对坡面土壤水分的影响，结果表明：（1）土壤最大蓄水量变动范围为186.40～245.47 mm，土壤有效水含量的变动范围为78.13～174.37 mm；（2）在中、低吸力段（<15×102 kPa）土壤含水量和土壤水吸力之间存在显著的幂函数关系。（3）当土壤含水量相同时，土壤水吸力从大到小依次为灌木林地>针阔混交林地>常绿阔叶林地>楠竹林地。灌木林土壤持水性能最好，针阔混交林次之，常绿阔叶林较好，楠竹林最差。植被类型主要是通过提高土壤有机质含量，改良土壤结构，降低土壤容重和增加土壤毛管孔隙度等过程对土壤的蓄水和持水性能产生作用。（4）探讨土壤水分特性，对于研究土壤-植物-大气连续体中水分的动态、土壤水分与作物吸水之间关系的机理具有重要意义。
- Abstract:
- The impacts of different woodlands on soil water in Jinyun mountain of Chongqing city were studied.The results showed that the soil maximal holding capacity is from 186.04～245.47 mm, the soil effective holding capacity is from 78.13～174.37 mm.There was a high function correlation between the soil moisture content and soil suction during the low and medium soil suction (<15×102 kPa).When the water content of soil is same, the soil suction sequence from high to low is:shrub forest>mixed wood>broadleaf forest>bamboo forest.So the shrub forest has the best soil water retention capacity, the next is mixed wood, then is the broadleaf forest, and the worst is the bamboo forest.The types of vegetation affect soil water characteristics by increasing the soil organic matter, improving the soil construction, receding soil bulk density and enhancing the soil porosity.It has important significance to study soil water characteristics for studying dynamic of the moisture in the soil-plant-atmosphere model and the mechanism between soil water and plant absorbing water.
