- Title:
- Study on Revegetation Effect of Returning Farmland to Forestry Combining Closure in Sand Covered and Loess Region in Wuqi County

- 摘要:
- 通过调查吴旗县覆沙黄土区不同时段封禁造林情况，并对此地区植被群落的重要值、物种丰富度、生物量等指标进行分析研究。结果表明：实施封禁造林3~4 a，一年生植物很快侵入，但整个群落无明显优势种；封禁造林5~6 a，禾本科、豆科、菊科的一些物种逐渐占据优势，形成了地带性植被；封禁造林10年后，植被基本恢复到与环境相适应的稳定群落。
- Abstract:
- The indexes of importance value, species abundance and biomass about vegetation community in sand covered and loess region in Wuqi county in different time-interval are analyzed, through investigating the situation of the closed vegetational type.The results indicates that the area during closing and afforesting forests about 3～4 years, the annual plant intruded quickly, but there were no obvious dominant socials in the vegetation community;the forests closed and afforested about 5～6 years, some species of the gramineous, leguminous and composite vegetation would inhabit the predominance as the characteristics of zonality plant;after the plants closed and afforested more than 10 years, the vegetation is basically coherent to the stable plant community.
