中文摘要	为了揭示石漠化地区不同植被类型土壤水分对降雨响应特征,选取花椒地、山豆根地、金银花地、撂荒地进行土壤水分原位监测,分析土壤水分在小雨、中雨、大雨、暴雨4种降雨事件中的响应过程,探究植被类型的降雨响应补给特征。结果表明:土壤层稳定程度对植被土壤储水量有影响,土壤水分变异系数越大,土壤层相对活跃,则土壤储水量相对较少;各植被土壤水分对降雨响应具有滞后性,表现为山豆根地>花椒地>撂荒地>金银花地。金银花地对降雨响应快,敏感性高。在不同降雨事件中,暴雨事件中各植被土壤水分响应最快;降雨量越大,土壤剖面有效补给量越多。各植被有效补给量表现为撂荒地(13.93 mm)>金银花地(13.90 mm)>山豆根地(12.28 mm)>花椒地(10.50 mm);当降雨量达到一定范围后,有效补给效率会下降,各植被有效补给效率表现为中雨>小雨>大雨>暴雨,撂荒地、花椒地、山豆根地大雨事件有效补给效率同小雨事件相比分别减少3.92%、0.24%、0.43%,金银花地减少12.11%;在雨季金银花地土壤保水性能高,对降雨响应较为敏感,有效补给量和补给速率较高,土壤储水量丰富。
英文摘要	To reveal the characteristics of soil moisture in response to rainfall in different vegetation types in rocky desertification area,we selected Zanthoxylum bungeanum(ZB),Lonicera japonica(LJ),Sophora tonkinensis(ST),and an abandoned land(AL)to monitor soil moisture in situ.Response and replenishment characteristics of soil moisture under light rain,moderate rain,heavy rain,rainstorm in different vegetation types were evaluated.Results showed that the stability of the soil layer had an impact on soil water storage in the vegetation.The larger the soil variation coefficient value,the more active the soil layer and the lower the soil water storage.The soil moisture of each vegetation showed an hysteresis response to rainfall,and is presented in this order:ST>ZB>AL>LJ.LJ responded quickly to rainfall and was highly sensitive.Among the different rainfall events,the soil moisture of the four vegetations had the fastest response during rainstorm event.The higher the rainfall,the more effective the replenishment of the soil profile.The effective replenishment amount is presented in this order:AL(13.93 mm)>LJ(13.90 mm)>ST(12.28 mm)>ZB(10.50 mm).When the amount of rainfall increased to a certain range,the effective replenishment efficiency of the soil moisture decreased.The effective replenishment efficiency of each vegetation was in this order:medium rain>light rain>heavy rain>rainstorm.Compared with the effective replenishment efficiency of soil moisture during light rain event,the effective replenishment efficiency of soil moisture in LJ,AL,ZB,and ST during heavy rain event reduced by 12.11%,3.92%,0.24%,and 0.43%,respectively.In the rainy season,LJ had high water retention capacity,was more sensitive to rainfall,had high effective replenishment amount and rate,and had soil with abundant water storage.
