摘　　要：对西南喀斯特地区2种不同建园方式柑橘园水土流失情况进行连续3a的定位监测,并研究了4种类型柑橘园土壤含水量的年动态变化。结果表明,2种不同建园方式柑橘园的土壤流失量逐年减少,坡地柑橘园的年径流系数大于梯地柑橘园;不同类型柑橘园土壤含水量与土壤层次、建园方式及柑橘园成土母质有关;柑橘园土壤含水量与月降雨量呈正相关,应在不同月份对柑橘园采取不同水分调控措施。Long-term stationary monitoring for 3 years in a row was conducted of soil and water loss in citrus orchards of (2 different) types of set-up,and studies carried out of annual dynamic changes in soil water content in 4 types of citrus (orchards) in northwest Guangxi.The results showed that generally soil and water loss declined year after year in the 2 citrus orchards of different set-up,and the runoff coefficient of the orchard on slopeland was higher than that on terraced fields;The soil moisture contents were related to soil profile,set-up of the orchard and parent material of the soil,and in particular positively to the monthly rainfall.Therefore,different measures for management of soil water regime should be adopted for these orchards in different month.
