摘要:
为探究不同恢复措施对退化高寒草甸的影响,研究了不同围封年限(0、4、13年)和长期施肥(N、P)下草甸群落特征和碳氮库的变化。结果表明:1)随着围封年限增加,物种丰富度指数和Shannon-Wiener指数显著降低,Simpson指数和Pielou指数呈先上升后下降的特征;长期N和P添加分别显著降低了物种丰富度指数和Shannon-Wiener指数。2)地上生物量和根系生物量在4和13年围封下均显著增加,且在4年围封时最高,而凋落物生物量则随围封年限增加而逐渐增加;长期施肥对生物量的影响不显著。3)围封后,植被碳和氮储量显著增加,其中地上生物量和根系碳、氮库均在4年围封时最高,凋落物碳、氮库则在13年围封时最高;长期施肥对植被碳储量无显著影响,仅长期N添加显著提高了地上生物量氮库。4)偏最小二乘(PLS)路径模型显示:围封和施肥导致环境因子发生变化,抑制了群落多样性,促进了植物生物量和植被碳库的积累,而植被氮库特征在施肥处理下发生变化。综上,围封整体上抑制了物种多样性,但能够促进群落生产力提高和植被碳氮库增汇;长期N添加对物种多样性和植被碳库无显著正效应,但促进了植被氮库增汇。
