摘要
选择6种不同植物及配置方式的林型,以流动沙地为对照,测定研究了陕北风沙区铁路防风固沙林在防风、固沙、调节小气候、改良沙地土壤养分含量等方面的效益,结果表明,不同配置结构的混交型铁路防风固沙林可低风速40.8%-78.9%,输沙量降低55.5%-98.1%,明显改善小气候条件,调节温湿度,对沙地土壤有明显的改良作用。
Six vegetation patterns were studied with comparison with the mobile dune.The effect of sand-fixation plantations in the north of Shaanxi was measured in terms of wind control,sand stabilization,micro-climate regulation and soil improvement.The result showed that different vegetation pattern can reduce wind speed by 40.8% to 78.9% and sand transfer reduced by 55.5%-98.1%,with significant effect of micro-climate regulation,moist improvement and soil improvement.
