摘要

为探明喀斯特坡地改为梯田后土壤水分的变化特征

以典型喀斯特坡地橘园和梯田橘园为研究对象

对不同深度土层(0—70 cm)土壤含水量进行1年 (376天)的连续监测。结果表明:(1)梯田橘园平均土壤含水量(32.64%)与坡地橘园(33.05%)差异很小

梯田橘园表层(0—10 cm)土壤含水量(43.35%)显著高于坡地橘园(34.24%)

两者土壤水分均呈现旱季变化相对平缓、雨季波动较为剧烈的变化规律

梯田橘园表层土壤含水量与下层有明显差异

而坡地橘园各土层土壤含水量差异较小。(2)不同雨量的降雨事件中

梯田橘园各土层含水量总体增长幅度较坡地橘园大;停雨后24 h内

梯田橘园表层土壤含水量的衰退速度较坡地橘园慢

但停雨后1周内

梯田橘园各土层含水量衰退速度总体较坡地橘园快。(3)梯田橘园与坡地橘园的平均相对可利用水分分别为0.37与0.38

与非喀斯特地区相比

梯田在喀斯特峰丛洼地的保水效果相对不明显。研究结果可为定量评价喀斯特地区坡改梯措施的保水效益提供一定的科学依据。

Abstract

In order to determine the variation characteristics of soil moisture after the transformation of karst slope land into the terraced field

the typical karst slope citrus orchard and terraced citrus orchard were taken as the research objects

and the soil water content of different depths soil layers (0-70 cm) was continuously monitored for one year (376 days). The results showed that: (1) The average soil water content of terraced citrus orchard (32.64%) was little different from that of sloping citrus orchard (33.05%). The soil water content (43.35%) in the surface layer (0-10 cm) of terraced orange orchard was significantly higher than that of sloping citrus orchard (34.24%). Both of them demonstrated a violent fluctuation in the rainy season and a relative gentle change in the dry season. In the terraced citrus orchard

there was a substantial difference in soil moisture between the surface soil and the lower layer

while there was no variation in the soil moisture among each soil layer in the sloping citrus orchard. (2) In the rainfall events with different rainfall amounts

the overall increase of soil water content in terraced citrus orchard was greater than that in sloping citrus orchard. Within 24 hours after the rain stopped

the decline rate of surface soil water content in the terraced orchard was slower than that in the sloping citrus orchard

but within a week

the water content of all soil layers in terraced orange orchard declined faster than that in sloping orange orchard. (3) The average relative available water of the terraced citrus orchard and sloping citrus orchard was 0.37 and 0.38

respectively. Compared with the non-karst region

the water conservation effect of terraced fields in karst peak-cluster depressions was relatively insignificant. The results of this study could provide a scientific basis for the quantitative evaluation of water conservation benefits of slope-to-terrace measure in karst area.
