| 摘 要： | 通过研究希拉穆仁草原退化过程,并以封育、灌溉、松土补播、干草覆盖等技术实施人工修复测试,对测试的试验地进行植被调查、土壤肥力化验和土壤种子库发芽试验,比较各种技术对当地退化草地的恢复作用及其各自的优缺点。结果表明:灌溉对退化草地的恢复作用最为明显;封育的恢复作用较为显著,但恢复能力总体来说只有灌溉的50%左右;松土补播和干草覆盖反而影响了植被的恢复。

| Abstract: | The process of degradation on Xilamuren grassland and artificial recovery measures were carried out such as enclosure,irrigation,soil loosen and reseeding,hay covering. Vegetation investigation,soil fertility assay and germination of soil seed bank were conducted to compare the recovery effects on degraded grassland in this region and the advantages and disadvantages among these techniques. Results showed that irrigation had most obvious effects on degraded grassland recovery;enclosure was also effective,bu... |
