| 摘 要： | 黄土高原半干旱退化山区，由于长期的乱垦滥伐，过度放牧，造成水土流失严重，自然植被退化。随着退耕还林草工程和自治区人民政府全区范围内禁牧政策的实施，经过人工坡地改造工程，该区自然植被得到了一定的恢复。研究结果表明:退耕还林、还草、全面封育、土地利用方式的改变加快了示范区生物多样性的演替，群落物种得以生长、生存，物种的多样性增加，群落的相对稳定性提高

| Abstract: | Disorderly felling and over grazing on semi-arid degraded mountain area in Loess Plateau lead to deteriorated plant and soil erosion.As the implementation of reafforestation project and forbiding grazing policy in Ningxia Autonomous Region,after sloping fields transforming project,the vegetation recovered to some extent. Research result showed:measures such as deforming and reafforestation,no grazing and changes in land using accelerated biodiversity succession in demonstration district, the plant community species developed, species diversity and plant relative stability increased. |
