为评估总结适用于沙化草地生态修复的技术模式,以锡林郭勒盟东乌旗严重沙化草地为研究对象,针对碟形风蚀坑、碗形风蚀坑、槽形风蚀坑以及沙丘4类风蚀地貌,因地制宜地选用不同的综合治理技术模式.结果显示,在采取修复措施第二年,记录到已确定植物23种,隶属7科21属,各样点群落高度为9.33~24.00 cm,群落覆盖度达到8.67%~30.33%,干草产量8.89~47.36 g/m2;修复第三年,记录到已确定植物12科30属34种,各样点补播物种有冰草、山竹岩黄耆、斜茎黄芪,植被高度为12.33~36.00 cm,群落盖度达到20.33%~48.67%,干草产量29.93~162.00 g/m2.相比修复第二年,其植被高度平均增幅66.67%,盖度平均增幅111.95%,干草产量平均增幅311.77%,治理效果显著.
Report on the effect of desertified steppe in Xilinguole League of Inner Mongolia
In order to evaluate and summarize the technical models suitable for ecological recovery of sandy grassland,heavily sandy grassland in Dong Ujimqin Banner of Xilingol League is taken as the research object.Choice of comprehensive treatment technology model for saucer blowout,bowl blowout,trough blowout,dune blowout adapting to local conditions.The results showed that in the second year of implementing restoration measures,23 identified plant species were recorded,belonging to 7 families and 21 genera.The community height ranged from 9.33 cm to 24.00 cm,the community coverage ranged from 8.67%to 30.33%,and the hay yield was 8.89 g/m2 to 47.36 g/m2.In the third year of restoration,34 plant species were recorded,belonging to 12 families and 30 genera.Includes replanted species such as Agropyron cristatum,Hedysarum fruticosum,Astragdlus laxmannii.The community height ranged from 12.33 cm to 36.00 cm,the community coverage ranged from 20.33%to 48.67%,and the hay yield was 29.93 g/m2 to 162.00 g/m2.Compared with the second year of restoration,the average increase of vegetation height was 66.67%,the average increase of vegetation coverage was 111.95%,and the average increase of hay yield was 311.77%.
