摘要:
在滇西北高原香格里拉县纳帕海周边区域，以荒草丛、自然恢复灌丛、自然恢复高山松次生林以及人工混交林等四种生态系统类型为研究对象，采用时空互代法，视它们为水土保持生态修复过程中不同阶段，研究不同生态系统的群落结构变化规律。通过对各生态系统的群落空间结构、物种多样性、均匀度、生态优势度分析表明，滇西北高原水土保持生态修复过程群落结构的复杂性依荒草丛→灌丛→人工混交林→天然次生林逐渐增加。荒草丛、5年生灌丛、13年生人工混交林和15年生天然次生林的灌木层生物量分别为0、8.1704 t/hm2、2.0449 t/hm2、3.7965 t/hm2，草本层生物量分别为7.4912 t/hm2、4.6812 t/hm2、3.9852 t/hm2和1.6966 t/hm2。
Abstract:
The wild grass, bush community, artificial mixed forest were regarded and natural secondary forest were regarded as the research subject of different stages in the process of ecological construction aimed at soil and water conservation around Napahai Lake in the northwest of Yunnan Province.The change of those community structures was studied by using spatio-temporal substitution method.The community spatial structure, the species diversity, evenness, ecological dominance in four ecosystems were analyzed, the results show that community structures become more and more complicated from the wild grass to natural secondary forest.Biomass of shrub layers of the wild grass, five-year-old bush community, thirteen-year-old artificial mixed forest and fifteenyear-old natural secondary forest was 0, 8.1704t/hm2, 2.0449 t/hm2, 3.7965 t/hm2, and that of their herb was 7.4912 t/hm2, 4.6812 t/hm2, 3.9852 t/hm2 and 1.6966 t/hm2 respectively.
