本文主要研究内容
作者赵志江,郭文霞,康东伟,崔莉,赵联军,李俊清（2019）在《川西亚高山岷江冷杉和紫果云杉径向生长对气候因子的响应》一文中研究指出：【目的】探讨川西亚高山地区各海拔生境处岷江冷杉和紫果云杉径向生长对气候因子的响应,为进一步揭示当地森林对气候变化的响应机制提供依据。【方法】分别获取王朗自然保护区中海拔与高海拔生境处岷江冷杉和紫果云杉的标准年表,分析年表同气候因子间的关系。【结果】中海拔生境处岷江冷杉生长在1990年后与年均气温存在一定程度的"分离效应";中海拔生境处岷江冷杉和紫果云杉生长与上年生长季(上年7月和8月)气温和上年生长季末(上年10月)降水量显著负相关(P<0.05),岷江冷杉生长与当年9月气温和降水量显著负相关(P<0.05),紫果云杉生长与当年2、6月月均最低气温显著正相关(P<0.05);高海拔生境处岷江冷杉和紫果云杉生长均与当年生长季前(上年11月、当年1月、当年2月)、当年生长季(当年7月)和上年生长季(上年6月)气温显著正相关(P<0.05),岷江冷杉生长还与当年6月份的降水量及上年8月份的气温显著负相关(P<0.05);滑动相关分析和年表特征年气候分析结果充分印证了各年表对月气候因子响应的可靠性。【结论】上年生长季气温的"滞后效应"对中海拔生境处的岷江冷杉、紫果云杉以及高海拔生境处的岷江冷杉生长均有显著影响;近几十年来,上年生长季末降水对中海拔生境处的岷江冷杉、紫果云杉以及高海拔生境处的紫果云杉生长都具有稳定而显著的抑制作用。
