摘要
为了进一步分析干旱地区蒙古栎混交林在水土保持方面的效果,在辽西沙区选择营建5 a的蒙古栎+大扁杏混交林进行了调查,以植被盖度、植物种类、地表径流量、土壤流失量作为指标开展分析,结果表明:蒙古栎混交林营建5 a后其林间植被的盖度(100%)、种类多样性(19种)均大于对照处理;林间的地表径流量、地表流失量均为0,极显著低于对照处理。辽西地区的蒙古栎+大扁杏的混交林对提高地表植被盖度、恢复植被多样性、降低地表径流及土壤流失等方面有着积极的作用。
In order to further analyze the effects of Quercus mongolica mixed forest on soil and water conservation in arid areas, a 5-year-old Quercus mongolica and Prunus armeniaca mixed forest was selected for investigation in the sandy area of western Liaoning Province. The vegetation coverage, plant species, surface runoff, the amount of soil loss was used as an indicator to conduct analysis.Result shows that the vegetation coverage(100%) and species diversity(19 species) of five-year-old Quercus mongolica mixed forest after the establishment of the mixed forest are greater than the control treatment;the surface runoff & surface loss in the forests are both 0,which is extremely significantly lower than the control treatment. The mixed forest of Quercus mongolica & Prunus armeniaca in western Liaoning Province has a positive effect on increasing surface vegetation coverage, restoring vegetation diversity, reducing surface runoff and soil loss, etc.
