摘要:
采取定性与定量相结合的方法，评价了岷江上游典型植物群落的稳定性。将植被盖度、多样性、复杂性、演替度等反映植被稳定性的数量特征指标结合气候、地形、土壤等外部环境因子建立评价体系，利用层次分析法确定指标权重，利用综合指数法计算群落稳定性。结果表明：源区植物群落中，云杉林、柳灌丛、窄叶鲜卑花灌丛、冷杉林、绣线菊灌丛有较高的稳定性值，沙棘和小果小檗灌丛稳定性值较低；草甸群落中，苔草草甸和白茅草草甸具有较高的稳定性值，蒿草草甸和高山草甸稳定性值较低。干旱河谷植物群落中，绣线菊灌丛、瑞香灌丛、小花滇紫草灌丛、小马鞍羊蹄甲-白刺花灌丛、莸灌丛有较高的稳定性值，西南野丁香灌丛、驼绒藜灌丛、川甘亚菊灌丛的稳定性值较低。
Abstract:
The plant community stability in the upper reaches of Minjiang River is evaluated using the methods of qualitative analysis and quantitative analysis. The index system was developed combining quantitative character indices reflecting vegetation stability, such as vegetation coverage, diversity, complexity and degree of succession with external environmental factors such as climate, topography and soil character, hence supplementing the insufficiency that previous researches on vegetation stability assessment take the only vegetation character into account. The weighting values of the relative importance of the indices are established by using the analytic hierarchy process (AHP), and the stability of plant communities are computed by using the synthesized index method.The results indicate: the plant formations of origin region, form. Picea asperata, form. Salix spp., form. Sibiraea angustata, form. Abies faxoniana, form. Spiraea spp. have higher stability, while Hippophae rhamnoides and form. Berberis amurensis have lower one. Form. Imperata cylindrical and form. Imperata cylindrica have a higher stability, form. Kobresia spp.and form. Sub-alpine have lower one. In the plant formations of the arid valley region, form. Spiraea spp, form. Daphne spp., form. Onosma farrerii, form. Bauhinia faberi,Sorphora vrcifolia, form. Caryopteris spp., form. Quercus cocciferoides have a higher stability, while form. Leptodermis purdom, form. Ajania breviloba and form. Ceratoides arborescens have lower one.
