“…Among the 11 sites, only DLH6 yielded cores less than 1000 years in length, and the longest sample was obtained at DLH3 going back to 404 AD. We compared our chronologies with an archaeological ring-width chronology and the Dulan chronology (Zhang et al, 2003a;Kang et al, 1997;Tarasov et al, 2003; , 2004). The comparisom revealed that dating trees from the arid and semi-arid regions can be very difficult because of the missing rings and replications and comparisons between chronologies are extremely beneficial to improve the accuracy of chronologies.…”

“…Since 1998, 1050 tree-ring increment cores have been extracted from 493 living trees at Zongwulong, Shalike and Qinghai Nanshan mountains (Figure 1) in the northeastern part of Qaidam Basin. The 11 sampling sites (DLH1-6, TJ1, and WL1-4) are located to the north of the Dulan Chronology site (Zhang et al, 2003a;Tarasov et al, 2003). Table I presents the details of these sites and the sample depths.…”

Tree-ring widths have been used widely in studies of environmental changes and reconstructions of past climate. Eleven tree-ring chronologies of approximately 800-1500 years long were developed from Qilian junipers (Sabina przewalskii Kom.) for northeastern Qaidam Basin, along the margin of the Qinghai-Tibetan Plateau. Previous studies have revealed that water usage stress is the most limiting factor for tree growth in the study region. To evaluate the impact of the combined effects of temperature and precipitation changes over time, we performed water balance modelling using 1955-2002 meteorological data. We found that the tree-ring widths were strongly correlated with variables representing soil moisture conditions obtained from the water balance model. Specifically we considered actual evapotranspiration (AE) to represent the combined effect of water use demand and moisture availability, deficit as the difference between potential evapotranspiration (PE) and AE to represent the severity of water use stress, and relative soil moisture as the measure of moisture availability. For certain individual monthly and seasonal combinations, the tree-ring chronologies explained up to 80% of the variation in the soil moisture variables in regression analysis, indicating very good potential for reconstruction of regional soil moisture conditions in the past. These soil moisture variables outperformed precipitation and Palmer's drought severity index in most cases. We reconstructed the soil moisture conditions from 566 AD to 2001, which revealed major dry and wet periods and a general trend toward a wetter condition during the most recent 300 years. By comparing with other proxies in the region, we concluded that the moisture conditions reconstructed from tree-ring widths very well reflected the climate variability at the interannual and interdecadal scales.

“…Instrumental measurement is sparse and short-term in southwestern China, but climatic conditions can be extended back several centuries with high-resolution climatic proxies. Tree-ring records are widely used as climatic proxies, because they provide annual resolution, precise dating and adequate duplicate data and have been proven to be an efficient proxy for past climate reconstruction [1][2][3][4][5].…”

A 457-year reconstruction of precipitation in the southeastern Qinghai-Tibet Plateau, China using tree-ring records

et al. 2013

This paper presents a 457-year reconstruction of precipitation in the southeastern Qinghai-Tibet Plateau using tree-ring records. Tree-ring samples were collected from the Hengduan Mountains in the southeastern part of the Qinghai-Tibet Plateau, China. A nearly 500-year chronology was developed using tree-ring width records. Correlation analysis shows moisture is the main factor limiting tree growth in this region. Ring-widths were significantly positively correlated with the Palmer Drought Severity Index (PDSI) and precipitation in many months. The highest correlation coefficient was found between the annual growth of trees and precipitation from the previous September to the current June (0.738). Based on this relationship, we reconstructed the precipitation history from 1509 to 2006. The reconstruction explains 54.4% (R 2 adj =53.5%, N=49, F=56.12) of the actual precipitation variation during the calibration period . During the reliable period of the reconstruction (1549-2006), some low-frequency climate signals are included, indicating this region has been getting wetter in the last 20 years. The reconstruction documents six apparently dry and five pluvial periods and the 17th century dry period lasted longer than any other. When compared with other recent studies, this study and these earlier reconstructions show a similar trend in the variation of drought and pluvial. Further spatial correlation analysis confirms that the reconstructed precipitation adequately represents the rainfall history of the entire Hengduan Mountain area. The Multi-taper method, a type of spectral analysis, reveals that precipitation in this area had significant (P<0.01) spectral peaks at 3-5 a, 60 a and 79-85 a.Abies Mill., Hengduan Mountains, precipitation reconstruction, Qinghai-Tibet Plateau, tree-ring width Citation:Gou X H, Yang T, Gao L L, et al.

“…In addition to modern geographical processes, studies on historical geographical progresses also made prominent achievements. In those studies, a large number of archives were used to retrieve the environmental evolution, including ice cores (Yao et al, 1997;Shi et al, 1999b), loess Liu et al, 1998), sporopollen (Song et al, 1999), speleothems (Wang et al, 2005b;Zhang et al, 2008c), tree rings (Zhang et al, 2003;Li et al, 2006) and historical documentary data (Chu, 1973;Ge et al, 2003). Some of the studies even reached an international advanced level.…”

Modern physical geography in China grew from Chinese traditional geography and has been profoundly influenced by the geographical disciplines of Euro-America and Russia. Since the 1950s, integrated studies of physical geography in China have made remarkable progress in the fields of comprehensive physical geographical regionalization, land studies, landscape ecology, and land surface geographical processes. During the past few decades, under the background of global change and rapid socio-economic transformation, a series of environmental and resources problems have boomed in China. To solve these problems and promote the development of integrated studies of physical geography, the following issues were proposed as research priorities: (1) coupling of land surface patterns and processes; (2) integrated research on regional responses and adaptation to global change; (3) analysis of human dimensions of the earth system; (4) ecosystem service research from a geographical perspective; (5) integration of multi-source data and model development; (6) integrated studies on unique geographical units; and (7) important global issues and relevant international programs.
