Abstract:

Influence of sod shoveling on wet meadows of the Tibetan Plateau was investigated based on the analyses of caloric values and ash content of wet meadow plants in different sod shoveling slashes. The results showed that caloric values and ash content of wet meadow plants were responded to the sod shoveling in a certain degree. Ash content was decreased after sod shoveling. And in the degraded plots, plants caloric values and ash free caloric values could be improved by sod shoveling at a certain depth. Caloric values and ash content could be used as indicators of responses of wet meadow plants to environmental disturbances. And sod shoveling had certain significance on wet meadow restoration on the plateau.

Key words: Wet meadow, Sod shoveling slashes, Caloric values, Ash content, The Tibetan Plateau

摘要:

为探讨草皮挖取对湿草甸湿地的影响,研究基于典型草皮挖取样地开展了湿草甸优势物种热值及灰分含量的研究。结果表明:湿草甸植物热值及灰分含量对草皮挖取扰动具有一定响应。草皮挖取可降低湿草甸植物灰分含量;在退化样地内适宜的挖取深度可提高植物干重热值及去灰分热值。草皮挖取结合水分波动等多种环境干扰可导致湿草甸植物热值、灰分含量的差异;热值及灰分含量可作为湿草甸植物响应环境干扰的指示指标。草皮挖取对高原寒湿草甸恢复具有一定意义。
