| 摘 要： | 利用气象站实测资料分析表明，林区和非林区蒸发、大气湿度、降水日数以及降水量有明显的差异；陕北长城沿线沙区的植树造林和防沙林带建设，已使沙尘暴天气从80年代中期开始显著减少；子午岭林区的大面积毁林使对流性雨量减少。

| Abstract: | Analysis of meteorological real data showed that differences of evaporation, rain days and precipitation between forest region and the areas without forests. The afforestation and sand break by the Great Wall in North Shaanxi reduced dust devil weather distinctly from mid term of 1980s. Convective precipitation was decreased bedause of damagmg of much forests. |
