Effects of climate warming on radial growth of Larix gmelinii in Wudalianchi, Heilongjiang Province
【Objective】The Longmen stone village lava platform is the main distribution area of the Larix gmelinii natural forest in the community of the Wudalianchi volcano group. In this study, we explored the response of the radial growth of L. gmelinii in Longmen stone village to climate warming over the past 51 years (1968-2018) and provided a scientific basis for the vegetation succession trend of the Wudalianchi volcano group under global warming. 【Method】We performed the Mann-Kendall test to determine the trend of temperature change and the years of possible abrupt air temperature changes over the past 51 years. We also analyzed the response characteristics of the radial growth of L. gmelinii to climate change over two periods (1968-1981 and 1982-2018) using tree-ring climatology. 【Result】We found that the mean air temperature of Wudalianchi has been increasing in the past 44 years (1975-2018) and that 1981 was the mutation point. After global warming, both the ring index and basal area increment of L. gmelinii decreased; the tree-ring index showed an upward trend, while the basal area increment showed a downward trend, but the changes were not significant. The “separation effect” appeared in the response of the radial growth to the increased air temperature. Together, water and temperature controlled the growth of L. gmelinii, but air temperature was the main factor affecting the radial growth. The response pattern of the radial growth to climatic factors was significantly affected by global warming. Meanwhile, the response sensitivity of the radial growth to the annual mean air temperature, annual mean minimum air temperature, and coldness index was significantly enhanced. However, the main factors that determined the ring width of L. gmelinii were the precipitation in November of the previous year and the mean minimum air temperature in February, March, and the pre-growing season of the current year. 【Conclusion】Although the climate warmed significantly in Wudalianchi after 1981, it did not have a significant impact on the radial growth of L. gmelinii. The reason for the “separation effect” and the significant changes in the response of the radial growth to climatic factors may be the drought stress after warming.

黑龙江五大连池处于大小兴安岭和松嫩平原的交错地带, 在过去210万年间经历了7次大规模的火山喷发, 是中国保存最为完好的内陆火山遗迹, 2010年被我国政府遴选为世界自然遗产提名地。为了科学、准确地阐述五大连池生态方面的突出普遍价值, 本文在《实施世界遗产公约操作指南》的框架下, 整合野外调查数据和文献资料, 在与其他相关世界遗产地充分比较的基础上, 较为全面地分析了五大连池的生态价值。五大连池植物地理特征交错, 区系来源广泛; 物种组成相对丰富; 发育在熔岩台地上的矮曲林反映了植物的特殊适应过程; 特有成因形成了陆生和水生两个完整的植被演替序列; 陆生植被演替同时存在普通演替和斑块动态演替两种模式, 在熔岩地貌上斑块动态演替模式更为随机而高效。上述生态特征充分展示了五大连池正在进行的生物生态过程, 体现了五大连池独特的生态价值, 为后续有效保护和深入科学研究提供了支撑。

大兴安岭是我国气候变暖的敏感地区。为比较在升温过程中不同地区落叶松(Larix gmelinii)径向生长对温度的响应差异, 在大兴安岭主脉南段、中段和北段进行树木年轮取样, 建立了各点年轮宽度年表, 根据年表第一主成分载荷系数分类最终合成南部、中部和北部各区年轮指数。利用相关函数分析了落叶松径向生长与温度变化的关系, 结合主成分分析对比了不同地区树木年轮宽度变化对温度的响应差异。结果表明: 落叶松径向生长对温度变化的响应呈现明显的南北差异(中部>北部>南部); 南部年轮指数与上年11月到当年4月的平均温度显著相关, 中部年轮指数与上年生长季(6-8月)和当年3-10月的平均温度显著负相关, 北部年轮指数与生长季前(4-5月)的平均温度极显著正相关。气候变暖背景下, 高温引起的区域暖干化使土壤水分成为限制落叶松径向生长的主要因子, 土壤干旱程度加剧使落叶松生长对温度变化的响应增强。胸高断面积增量指示的落叶松生产力经历了从响应低温胁迫到响应高温引起的水分胁迫的转变。未来几十年, 若温度持续升高, 大兴安岭地区落叶松径向生长量将呈南部和中部降低、北部升高的趋势。

Based on the theory and methodology of dendrochronology, the tree ring width chronology of Pinus sylvestris var. mongolica in Mangui of Great Xing' an Mountains was developed, and the relationships between the standardized tree ring width chronology and local climate factors (temperature and precipitation) as well as the effects of climate factors on the P. sylvestris var. mongolica radial growth were analyzed. In this region, the mean monthly temperature in April-August of current year was the main factor limiting the radial growth, and the increasing mean monthly temperature from April to August had negative effects to the radial growth. The simulation of the variations of the radial growth by the mean monthly temperature change in April-August showed that the radial growth of P. sylvestris var. mongolica would present a declining trend accompanied with the warmer and drier regional climate condition.
