摘要:
基于油松与沙棘带状混交试验，以油松纯林为对照，研究了两类样地水土保持指标、土壤理化性质相关指标及林木生长情况变化。结果表明，油松沙棘混交林样地枯枝落叶厚度、总量、容水量分别比纯林提高了104.8%，90.8%，83.4%，油松沙棘混交林样地土壤有机质、全氮、通透速度分别比纯林提高了110.%，132.1%，66.7%；混交林能够有效改良土壤理化性质，提高土壤肥力，促进林木生长，提高林分的效益，减轻病虫害，增强水土保持能力。
Abstract:
Based on the investigation of reconstructing mixed forests of Pinus talulaeformis and Hippophae rhamnoides, in comparison with pure Pinus tabulaeformis forests, the criteria and indicators of soil and water conservation, soil physical and chemical properties, and tree growth for two types of sample spot were studied.The results of study showed that the quantities, thickness and water conservation function of forest litters in mixed sampling plot were higher respectively 104.8%,90.8%,83.4% than pure stands. Results also showed that organic matter content of soils, the contents of soil total nitrogen, soil permeability in mixed sampling plot were higher respectively 110.%,132.1%,66.7% than pure stands. The results also showed the mixed forest should be one of the most effective available methods to improve ecological benefits and the conservation of soil and water.
