芨芨草改善沙漠小气候的研究

Studies on Improving Microclimate of Desert by A.Splendens

对人工种植3年的古尔班通古特沙漠边缘芨芨草试验园区的防风固沙效果进行研究.结果表明,种植芨芨草后对沙漠小气候有较好的改善作用,可以明显降低风速32.00%～85.77%,降低土壤温度10.07%～21.32%,提高空气湿度10.99%,从而缓解空气温度骤然变化.

Planting A. splendens is one way of wind proof and sand preventation. Throughout experiments and investigation, the result shows that planting A. splendens can improve microclimate of desert. A. splendens can decrease velocity of wind to 32.00% - 85.77 %, decrease temperature of soil 10.07 % - 21.32 %, raise humidity of atomsphere to 10.99% ,slow down the sudden change of temperature in the desert.
