| 摘 要： | 以内蒙古阴山北麓四子王旗和武川县的荒漠草原农牧交错带弃耕地为研究对象,研究不同恢复措施和恢复年限对弃耕地草本植物群落的影响。研究结果显示,在相对干旱的四子王旗和相对湿润的武川县,荒漠草原弃耕地分别种植中间锦鸡儿和苜蓿有利于地带性植被恢复演替,可增加草本群落的盖度和地上生物量。随着弃耕年限的增加,四子王旗和武川县弃耕地总的物种数、多年生草本物种数和一、二年生草本物种数呈减少趋势,地带性优势物种在群落中逐渐占主导地位,植物群落的盖度和生物量出现了先降低后增加的趋势,植物群落的Shannon-Wiener指数和Margalef丰富度指数呈递减趋势。在荒漠草原合理的人工干扰有利于弃耕地的植被恢复,弃耕地的植被恢复演替是个漫长的过程,弃耕地的再利用要慎重。

| Abstract: | This study took abandoned land of desert steppe located in Siziwangqi and Wuchuan County as study objects to study how herbaceous community was influenced by different restoration measures and periods. The results showed that planting Caragana intermedia in the abandoned land of Siziwangqi and Medicago sativa in that of Wuchuan County could promote restoration succession of the zonal vegetation and increase the coverage and aboveground biomass of herbaceous community. With the increase of abandoned time, the number of total species, perennial herb species and annual and biennial herb species, and Shannon-Wiener index and Margalef index of plant community in the abandoned land of the two areas tended to decrease, while the zonal dominant species dominated the community gradually. Additionally, the coverage and biomass of plant community showed a trend of first decrease and then increase with the increase of the abandoned time. Therefore, the reasonable artificial disturbance in desert steppe would be beneficial for vegetation restoration of the abandoned land. The vegetation recovery of the abandoned land is a long process, so the abandoned land should be used cautiously. |
