Soil water infiltration characteristics and influencing factors in different types of rubber forests
摘要
Abstract
[Objective]The aims of this study are to explore the soil water infiltration characteristics and influencing factors of different forest types rubber forest,and to provide data support for building of efficient and sustainable rubber forests.[Methods]A single rubber forest(SR),rubber artificial rain forest composite system(AF),rubber-puzzle composite system(AR),rubber-cocoa composite system(RC),rubber-tea tree composite system(RT)were selected as the research objects.Soil physical properties and soil moisture infiltration performance were determined and analyzed.Kostiakov,Philip,Horton model were used to fit and evaluate the infiltration process.[Results]Examination of the 0-100 cm soil profile revealed that SR bulk density was the highest,while porosity,field water holding capacity and saturated water holding capacity were the lowest.The initial infiltration rate(0.03 cm/min),average infiltration rate(0.009 cm/min),and steady infiltration rate(0.005 cm/min)of SR were significantly lower than those of rubber composite forests.The Horton model effectively fitted the infiltration process of rubber composite forests,with the model's parameters holding physical significance.With the exception of capillary porosity,soil physical properties showed significant correlation with the initial infiltration rate(p＜0.01),and with the total cumulative infiltration amount and soil saturated water conductivity(p＜0.05),but not with the average infiltration rate(p＞0.05).The cumulative infiltration before stable infiltration was significantly affected by soil water retention(p＜0.01).[Conclusion]Combined with the field infiltration process,the initial infiltration rate,steady infiltration rate and accumulated infiltration before steady infiltration were used to evaluate the soil water infiltration and storage performance of different forest types of rubber plantations.The soil water-holding capacity and permeability of SR were inferior to those of rubber composite forests,with RC demonstrating the highest soil water-holding capacity and permeability.Additionally,RT composite forests exhibit the best soil infiltration performance,highlighting the importance of intercropping tea and cocoa in improving soil structure and hydrological properties.关键词
