该文依托于小兴安岭典型阔叶红松(Pinus koraiensis)林9 hm2森林动态监测样地,对样地内林窗边缘主要树种红松和臭冷杉(Abies nephrolepis)进行生长释放判定分析,重建了冠层树木的干扰历史。结果表明:整体上林窗木与非林窗木的生长变化百分率变化规律基本一致,而不同林窗间生长变化百分率存在明显的差异,林窗干扰及其产生的影响存在较大的变异性。在1733–1738、1748–1752、1769–1771、1798–1801、1827–1833、1841–1844、1935–1939及1968–1973年间红松生长释放较强,其中1752、1770、1800、1830、1842、1937及1970年出现了明显的干扰峰;在1889–1904、1932–1938、1947–1973和1986–2005年间臭冷杉生长释放较强,其中1894、1934、1951、1968和1990年出现了明显的干扰峰。红松干扰存在2.0 a、3.5 a、3.8 a、7.3–7.9 a和9.1–18.2 a的显著周期,臭冷杉干扰存在3.5–3.6 a、7.5–48.8 a和65–85 a的显著周期。风干扰是典型阔叶红松林干扰释放的主要因子,异常温度也影响该地区树木生长释放事件。太阳活动通过影响局地风速、温度、降水等气候因子以及其他大尺度气候模态影响林窗动态,可能是小兴安岭典型阔叶红松林的干扰机制之一。
Based on the 9 hm2 forest dynamic monitoring plots of typical Korean pine broad-leaved Pinus koraiensis forest in Xiaoxing’anling, this paper analyzed the growth and release of the main tree species Abies nephrolepis in the margins of the shelterbelts and reconstructed the canopy trees Interfere with history. The results showed that the change law of the percentage of growth changes was the same in the whole forest and non-forest trees, but there was a significant difference in the percentage of growth changes between different forest gaps. There was great variability in the influence of the gap and its impact. In the 1733-1738, 1748-1752, 1769-1771, 1798-1801, 1827-1833, 1841-1844, 1935-1939 and 1968-1973, the growth of Korean pine was strongly released, of which 1752, 1770, 1800, 1830, 1842 1937 and 1970. The growth and release of A. fir were stronger in 1889-1904, 1932-1938, 1947-1973 and 1986-2005, of which obvious differences occurred in 1894, 1934, 1951, 1968 and 1990 The interference peak. Pinus thunbergii had significant periods of 2.0 a, 3.5 a, 3.8 a, 7.3-7.9 a and 9.1-18.2 a. There were significant periods of 3.5-3.6 a, 7.5-48.8 a and 65-85 a in A. fimbriacus interference. Wind disturbance is the main factor of the disturbance release of typical Korean pine broad-leaved forest, and the abnormal temperature also affects the tree growth and release events in this area. Solar activity may affect the gap dynamics by affecting climatic factors such as local wind speed, temperature and precipitation as well as other large-scale climate modalities, which may be one of the interference mechanisms of typical broad-leaved Korean pine forests in the Xiaoxing’an Mountains.
