| 中文摘要: |
| 以云南白马雪山国家级自然保护区曲宗贡区域大果红杉观赏季观赏特征为目标，采用红外相机进行大果红杉物候监测，通过与固定样地结合数据分析，了解观赏特征变化规律。结果表明，大果红杉叶各阶段的物候变化与海拔、温度、湿度、株密度等有直接关系，海拔越高，大果红杉叶变色时间越早，落叶期越短；气温越高、降雨量越少，叶变色时间越晚；株密度对叶变色期影响不显著，但对落叶期影响明显，株密度与落叶期长呈正相关关系。 |
| 英文摘要: |
| To research the ornamental characteristics of Larix potaninii var. australis in Quzonggong area of Baima Snow Mountain National Nature Reserve in Yunnan, infrared cameras were used for the phenological monitoring of Larix potaninii var. australis, the changes of ornamental characteristics were studied by combining data analysis with fixed plots. The results showed that the phenological changes of the leaves of Larix potaninii var. australis were directly related to altitude, temperature, humidity and plant density, and the higher the altitude, the earlier the leaf discoloration time and the shorter the defoliation period; the higher the temperature and the less rainfall, the later the leaf discoloration time; the effect of plant density on the leaf color change period was not significant, but the effect on the defoliation period was significant, and the plant density was positively correlated with the defoliation period. |
