针对呼伦贝尔新巴尔虎左旗沙地流动沙丘起伏较大,立地条件复杂,治理困难等情况,通过采取机械方格沙障与乔灌草相结合综合治理技术,使项目区植被的平均高度、盖度及物种分别提高到74.37cm、40.10%和15种,土壤有机碳、全磷、速效磷、水解性氮含量分别增加了132.02%、6.62%、145.3%、22.22%。说明治理后植被恢复状况良好,能够迅速提高土壤全磷、全氮养分和有机质的含量等,生态环境得到明显改善。 In view of the fluctuating mobile sand dunes in Xinbaerhuzuoqi sandy land of Hulunbeier, complicated site conditions and difficult management, the average height of the vegetation in the project area is covered by adopting the integrated treatment technology of mechanical gridding sand barrier, The soil organic carbon, total phosphorus, available phosphorus, and hydrolyzable nitrogen increased by 132.02%, 6.62%, 145.3% and 22.22%, respectively, to 74.37cm, 40.10% and 15 species, respectively. It shows that the vegetation restoration is in good condition after the treatment and the content of soil total phosphorus, total nitrogen and organic matter can be rapidly increased, and the ecological environment is obviously improved.
