- 摘要:
- 土壤水分是喀斯特地区植被恢复的主要限制因素之一。为促进喀斯特地区生态修复,通过对花溪水库石灰岩区3种主要植被类型土壤水分特性、土壤孔隙状况及土壤碳、氮、磷含量研究,分析植被类型及土壤性质对土壤水分的影响。结果表明,表层土壤含水量表现为灌丛>竹林>草地,20~40 cm土层则表现为灌丛草地>竹林。表层土壤灌丛总孔隙度较大,高于58%,草地总孔隙度较低,竹林居中。竹林中渗透系数较高,显著高于灌丛及草地,蓄水能力表现为灌丛>草地>竹林,水分较多地储存于20~40 cm土层中。相关性分析表明,土壤容重和孔隙状况与土壤蓄持水能力极显著相关,毛管持水量和渗透系数与土壤含水量极显著相关。土壤有机碳含量与土壤容重、总孔隙度、毛管孔隙、毛管持水量、排水能力及渗透系数存在显著或极显著相关关系。因此,喀斯特地区植被类型及土壤性质会影响土壤水分有效性及蓄、持水能力,从而影响植物生长。在今后对喀斯特地区土壤水分特性的研究中应着重关注地形及气候对当地水分的影响。
- Abstract:
- Soil moisture is one of the main limiting factors for vegetation restoration in Karst Areas.This paper analyzed the influence of vegetation types and soil properties on soil moisture by studying the soil moisture characteristics, soil pore conditions and soil carbon, nitrogen and phosphorus contents of three main vegetation types in the limestone area of Huaxi Reservoir. The research results have certain guiding significance for the ecological restoration of Karst Areas. The results showed that the water content of surface soil was shrub>bamboo forest>grassland, and that of 20-40 cm soil layer was shrub>grassland>bamboo forest. The total porosity of the surface soil shrub was large, higher than 58%, and the total porosity of the grassland was low, and the bamboo forest was in the middle. The permeability coefficient of bamboo forest was significantly higher than that of shrub and grassland. The water storage capacity were shown as shrub>grassland>bamboo forest, and more water was stored in 20-40 cm soil layer. Correlation analysis showed that soil bulk density and pore condition had a very significant impact on soil water storage capacity, and capillary water capacity and permeability coefficient had a very significant impact on soil water content. There was significant or extremely significant correlation between soil organic carbon content and soil bulk density, tolal porosity, capillary pore, capillary water capacity, drainage capacity and permeability coefficient. Therefore, vegetation types and soil properties in Karst Areas had an impact on soil water, affecting its water availability and water storage capacity, thus affecting plant growth. In the study of soil moisture characteristics in Karst Areas in the future, we should pay attention to the influence of topography and climate on soil moisture.
