甘肃省中部是东亚夏季风活动边缘带,也是我国北方环境敏感带,降水是制约当地农业社会发展的重要因素,因此对该区域过去降水变化开展研究有重要意义。本文在甘肃中部渭源县竺尼山采集油松树轮样本,建立了STD和RES年表。计算表明,RES年表与上年8月到当年7月的年降水总量相关最高(r = 0.59),二者存在比较一致的变化趋势,因此竺尼山RES年表可以代表当地过去降水的变化信息,它与同处于东亚季风边缘带的兴隆山和吐鲁沟的树轮年表(也被用来重建了当地的年降水变化)显著相关。三个地点树轮宽度变化一致,树木径向生长均受控于降水。 |

Background, aim, and scope The central Gansu province is the margin of the East Asian Summer Monsoon (EASM), and the environmentally sensitive region as well. The EASM related summer precipitation is an important factor for the local economical development. As such, it is very important to recognize the precipitation variations in the past. In this paper, Chinese pine from Gansu province was used to investigate the precipitation variations in the past century and to clutch some clues concerning the strength variations of the EASM in the study area as well. Materials and methods Chinese pine cores were collected on Mt. Zhuni which is located in the central Gansu province. In the laboratory, the standard dendrochronological processes were employed, and the ring-widths of each core were measured with a precision of 0.001 mm. After crossdating, the COFECHA program was used to control the quality of cross-dating. STD and RES chronologies were developed using ARSTAN program. Pearson correlation analyses were used to identify the relationship between tree-ring chronology and climate factors. The precipitation and temperature from Lintao meteorological station were employed to do ring-width climatic response analysis. By using the KNMI Climate Explorer dataset (http:// www.knmi.nl), we also explored the spatial representiveness of our precipitation-related chronology within the large-scale of the EASM margin areas. Results The results showed that both RES and STD chronologies were positively correlated with precipitation and negatively with temperature. This was the typical tree-growthclimate response pattern in the arid and semi-arid region. This was a quite similar finding to the previous treering studies on the Chinese Loess Plateau. We found that STD was highly correlated with the temperature and RES with precipitation. The highest correlation was given to RES chronology with the total precipitation from prior August and current July, with r = 0.59. That is to say that the RES chronology could represent the annual precipitation variations in the Mt. Zhuni. Meanwhile, no high correlations were found between chronologies (both STD and RES) and local PDSI dataset. This is because that the study region is located in the margin of the PDSI grid with complicated topography and climate conditions, the 2.5°×2.5° PDSI grid is too big to represent the true conditions of all areas in one grid. We also observed that RES chronology of Mt. Zhuni was significantly correlated with those of Mt. Xinglong and Tulugou which were located in the EASM margin too, with r = 0.51 and 0.52 separately. Discussion The study region is located on the western Loess Plateau. The precipitation is mainly concentrated during July to September caused by EASM. Strong EASM leads to more precipitation, and vice versa. In our study, the RES chronology of Mt. Zhuni could be regarded as the precipitation proxy indicating the strength variations of the EASM. We found that 1891 and 2011 were the visible bizarre driest years in the study region during the entire series. |
