| 摘 要： | 在北方农牧交错带——克什克腾旗地区,选择不同退化程度(轻度退化、中度退化、重度退化)草地为样地,并以同类未围封草地作对照,研究围封措施下,各类退化草地组成结构、植被盖度与高度、生物量等恢复情况.结果表明:轻度退化草地围封后在较短的时间内植被就可得到恢复;中度退化草地围封后需要较长的时间恢复,一般需要5年才可进行利用;重度退化草地围封5年后退化程度有所减轻. |
| 关 键 词： | 农牧交错带 生态恢复 围封 草地 |

| Abstract: | The ecotone between agriculture and pasture in Keshiketeng,by taking the different degree of degraded grassland(mild degraded grassland,moderate degraded grassland,specific weight degraded grassland) as the place of samples,and by the comparison of non-enclosed grassland,the restored condition of the structure of grass group composition,the vegetation height and output for each kind of degraded grassland are discussed.The result indicats that after enclosing the vegetation of the mild degraded grassland the... |
