关键词：甘蒙柽柳;乔木状;树轮;径流;风速 Abstract Aims The objectives were to identify the age of the arboreous Tamarix austromongolica in the flood plain area of the Qinghai Plateau and clarify the response patterns of T. austromongolica’s growth to the environmental factors. We focused on social issues about whether the T. austromongolica should be protected and how to protect in the reservoir area of a hydropower station. Methods In this study, arboreous T. austromongolica in both reservoir submerged and non-submerged areas were sampled and measured based on the dendrochronology method. The ages were estimated based on the geometrical characteristics of the pith and the identified age of the inner ring. The correlation and response analysis showed the relationship between T. austromongolica’s growth and environmental factors. Important findings We accurately determined the age and historical growth dynamics of the T. austromongolica with large diameter at breast height (DBH). The results showed a special accretion phenomenon in arboreous T. austromongolica, which accelerated the DBH increasing, i.e. no direct relationship existed between the plants’ DBH and ages of the individuals. Radial growth of T. austromongolica, increased rapidly in the 1970s and 1980s and began to stabilize in the late 1980s, and mainly responded to the runoff in July and August of the Yellow River. Increasing runoff would promote the radial growth of T. austromongolica. The growth of the immaturate plant showed significant negative correlation with the wind speed in the growing season. The results will be of theoretical significance to the formation of the special morphology of the T. austromongolica, and will provide scientific practical guidance in designing the protection schemes.
研究区属于秦岭地槽褶皱系的青海南山冒地槽带, 断裂构造发育。黄河对高原面不断侵蚀, 形成阶地和较为宽大的河谷, 并在河流弯曲凸岸形成河漫滩。河漫滩以石砾质冲积土和沙质冲积土为主, 土层较厚, 土壤发育程度差。在此之上分布有少量耐旱耐水抗风且耐碱土的植被, 典型的有甘蒙柽柳和小叶杨(Populus simonii)。该区域为温带大陆性干旱气候, 常年低温干旱, 据兴海气象站1981-2010年数据统计, 全年平均气温1.7 ℃, 最暖月在7月, 平均气温12.7 ℃, 最冷月在1月, 平均气温-11.0 ℃。降水稀少, 且主要集中在5-9月, 最大降水量出现在7月, 平均7月降水总量约86.6 mm, 年降水总量约为377.8 mm。2-4月为该地大风发生频率最高的季节, 受到山地地形的影响, 东西向山谷风偏大。 本研究主要针对羊曲水电站淹没区然果村甘蒙柽柳林(35.54° N, 100.16° E, 海拔2 678 m)开展研究, 同时也涉及了库区附近非淹没区班多村甘蒙柽柳林地(35.33° N, 100.26° E, 海拔2 730 m)(图1)。然果村林地甘蒙柽柳种群呈斑块状分布, 径级呈现较强的正偏态和尖顶分布特征, 胸径集中分布在20-30 cm。林地具有大量胸径超过30 cm的植株, 其中测量胸径值最大为132.1 cm, 该植株被媒体称为“柽柳王”。胸径20 cm以上的植株平均树高约为8 m。班多村林地甘蒙柽柳种群径级呈对称、常峰态分布, 较然果村具有更多的胸径超过30 cm的植株, 然而超过50 cm的植株在该区域十分罕见。两地甘蒙柽柳平均胸径和树高无显著差异, 且林下均缺乏幼苗更新。 显示原图|下载原图ZIP|生成PPT 图1青海同德县甘蒙柽柳采样点。 -->Fig. 1Sampling sites of Tamarix austromongolica in Tongde, Qinghai. -->
1.2 树轮样本采集及测量
我们于2016年11月下旬赴青海省同德县开展了实地调查, 利用直径5.15 mm的生长锥着重针对胸径较大的甘蒙柽柳进行采样并同时对其胸径进行测量。在然果村以及班多村分别采集了37株和15株活立木的树芯样本, 同时分别获取了4株和1株倒木圆盘样本(表1)。针对个别胸径较大且疑似多株合生树木获取多根样芯, 如“柽柳王” (编号RG-X05), 我们进行了5个方向的树芯采集。由于然果村甘蒙柽柳林普遍受到泥石流等灾害的影响, 树木个体存在损伤, 采样时尽量避免树木损伤部位, 对较为明确的竖直干材进行样本采集。依照同样的方法, 在班多村进行了树轮样本的采集。取样中, 尽量钻取到树木髓心位置或者能够在树芯上显示出树轮圆弧的近树木髓心位置, 为后续的树龄准确判断提供依据。 Table 1 表1 表1同德县甘蒙柽柳采样树木年龄 Table 1Ages of sampling Tamarix austromongolica in Tongde County

同德县甘蒙柽柳的径向生长主要与黄河径流流量以及风速存在较为显著的相关性。甘蒙柽柳径向生长与7、8月黄河径流流量之间存在正相关关系, 显著与7月径流正相关及响应关系(p < 0.05)体现在班多村研究区(图3), 在然果村则与8月的径流量间的相关性更强(图4)。 显示原图|下载原图ZIP|生成PPT 图3班多村甘蒙柽柳生长与径流量及风速的相关及响应。左侧为甘蒙柽柳径向生长与逐月径流流量的相关及响应, 右侧为径向生长与月平均风速的相关及响应。横坐标p表示前一年的月份, 误差条表示95%置信区间。 -->Fig. 3Correlation and response relationship of Tamarix austromongolica growth to monthly runoff and wind in Banduo Village.

甘蒙柽柳径向生长与风速之间的显著负相关主要发生在植被生长季, 在班多村, 甘蒙柽柳生长与当年4-8月的风速之间存在显著的负相关(p < 0.05), 明确的显著负响应发生在当年的5-6月(图3)。而在然果村, 甘蒙柽柳径向生长与风速之间的显著负相关关系发生在生长季早期或是生长季前, 同时响应分析结果表明, 径向生长与各月平均风速主成分向量的回归函数并没有达到95%显著性水平, 然果村甘蒙柽柳径向生长对月平均风速不存在显著的响应过程(图4)。 主要研究区年表与环境因子的滑动相关的结果表明, 甘蒙柽柳生长与环境因子的相关关系在时间尺度上存在较为剧烈的变化。近50年, 该流域径流7月径流量与然果村甘蒙柽柳生长的相关性逐渐减弱, 与此同步, 8月份径流流量与甘蒙柽柳生长的相关逐渐增强(图5)。 显示原图|下载原图ZIP|生成PPT 图5然果村甘蒙柽柳生长与径流流量的滑动相关。不同颜色所对应的数值表示不同的相关系数。 -->Fig. 5Moving correlation between Tamarix austromongolica growth and monthly runoff.
