腾格里沙漠月亮湖公路沿线退化白刺沙堆封育及其防沙效益

Study on Techniques of Vegetation Restoration in Arid Region-A Case Research Along the Yuelianghu Highway in the Tengger Desert, China

通过对腾格里沙漠月亮湖公路路域退化白刺沙堆地进行围栏封育及人工促进更新复壮效果的调查分析表明:在干旱荒漠地区,封育和人工促进更新技术可使路域植被盖度提高17.4%,新增植物13种,植株密度增加28株/m2,粗糙度增大18.3倍,输沙量降低5.7倍,风速降低11.37%。

Fenced Nitraria torngutorumcones with wire and sowing seeds in desert region show that along two sides of Yuelianghu highway,compared with unenclosed Nitraria torngutorum conesvegetation coverage were enhanced by 17.4 and species diversity, density, roughness respectively increased 13 categories,28 individual plants/m 2 ,18.3 times and sand flux and wind speed decreased 5.7 times and 11.37%.
