摘要
作者对库布齐沙漠不同立地条件下的沙柳生长情况进行了调查,着重调查了沙埋、风蚀对沙柳生长的影响,并研究了流动沙丘迎风坡沙柳根系的生长特性,为进一步提高沙柳造林成活率和生长量提供依据。沙柳的适宜的造林条件是30 cm以上的平缓覆沙地或流动沙地中下部,最好有沙埋的存在,考虑到流动沙地的风蚀和干沙层对生长的影响以及采取的深栽抗旱措施,造林插条长度以50 cm^70 cm为宜。适度沙埋利于沙柳的生长,风蚀是影响流动沙丘造林成活和林木生长的最重要因素之一,在沙地造林时,尽量避免风蚀,在风蚀严重的地区,应该设沙障防止风蚀。
Based on the research of the growth of Salix psammophila in different site conditions of Kubuqi desert,Middle-lower part of mobile dunes or gentle sand which covering sand more than 30cm are suitable site condition for afforestation of Salix psammophila.We mainly studied on the influence of sand bury and wind erosion to its growth and the growth characters in wind ward slope of mobile sand was also researched according on the growth characters.It will provide a theoretical basis for improving the survival rate and the growth rate of the Salix psammophila.
