乌审旗内沙漠面积很大,沙丘逐步向南部和东南部移动,埋没了大量的农田和牧场。这些沙丘既大又高,最高的达8—10立,最低的也有3—4米,并且大部分是新月型的流动性沙丘,基本固定沙丘的植物复盖仅占40%左右。因此,只要有一点风,沙子就满天飞扬,在沙丘背风面生长的沙柳也被埋的很深。不过,这些沙柳生长的很好,也就证明沙柳是固沙造林的好树种。为了彻底改造沙漠,我的意见是:在生有沙柳的新月型大沙丘上,最好是进一步种植沙蒿,使它同沙柳混合起来,其方法是从下部到上部,大型的沙丘栽1/3,中型的沙丘栽1/2,这样经过3—5年就能把沙丘基本上固定起来。因为在生长沙 Wushenqi desert area is very large, sand dunes gradually move to the south and southeast, buried a large number of farmland and pastures. The dunes are large and tall, reaching a maximum of 8-10 and the lowest are 3-4 meters. Most of them are crescent-shaped flow dunes, with only about 40% covering plants in essentially fixed sand dunes. Therefore, as long as there is a little wind, the sand is full of flying sand Salix growing in the leeward of the sand dune is also buried deep. However, these Salix grow well and prove Salix is ​​good for afforestation. In order to completely remodel the desert, my opinion is: On the crescent-shaped sand dune with salix, it is best to further plant the safflower sand so that it can be mixed with salix, from the lower part to the upper part. Large dunes Planted 1/3, medium-sized dune planted 1/2, so after 3 to 5 years will be able to basically fixed sand dunes together. Because in the growth of sand
