以2010年中国地图出版社出版的《世界分国地图》中的“哈萨克斯坦、塔吉克斯坦、吉尔吉斯斯坦、乌兹别克斯坦和土库曼斯坦”5国的地图为数据源。
1、 对2010年中国地图出版社出版的《世界分国地图》中的“哈萨克斯坦、塔吉克斯坦、吉尔吉斯斯坦、乌兹别克斯坦和土库曼斯坦”5国的纸质版地图进行数字化高精度扫描; 2、 利用ARC/INFO软件对扫描图片中进行手工矢量化,并按照原图中的属性进行属性数据的标注,再以地图中经纬度坐标为控制点进行地图重投影,选用WGS84投影,经纬度坐标。
本数据由中国科学院新疆生态与地理研究所负责数据加工, 由专业人员进行矢量化,误差控制在2个像素内,保证了矢量化的界线与地形图的界线完全吻合,数据精确度高达99%。

论文题目:Rb/Sr指示的伊犁盆地末次冰期环境演化
论文摘要:Rb/Sr ratios of loess sediments in the monsoon-dominated Chinese Loess Plateau have been regarded as a proxy for East Asian Summer Monsoon intensity. However, their paleoclimate significance of loess sediments in westerlies-dominated Central Asia is still unclear. Here, we reported Rb-Sr geochemical characteristics of eolian sediments and paleoclimate significance in the westerlies-dominated Central Asia. The results show that Rb element is related to silt-fraction, while Sr element is enriched in silt and clay components. The change of Rb/Sr ratio in the Yili Loess mainly depends on the enrichment degree of Sr element, which can be regarded as an index for westerly wind circulation intensity and precipitation

论文题目:中亚干旱区草地植被物候对气候变化的响应
论文摘要:Climate change has caused an acknowledged advance of spring phenology, but the variation of autumn phenology is diverse for advancement, delays and no change have all been detected. In this study, we use the start (SOS) and end (EOS) of the growing season that retrieved from GIMMS NDVI3g to investigate the variation trend of grassland phenological events and their relations with air temperature and total precipitation from 1982 to 2015 in arid Central Asis (ACA) through Empirical Orthogonal Function (EOF) analysis, Theil-Sen median analysis and partial correlation analysis. The findings illustrated that SOS/EOS has significantly advanced/advanced in 22.16%/13.24% of the study areas during 1982-2015. The variations of SOS and EOS together lead to slight prolonged LOS, with a narrow victory of 0.57% of the study areas. We found that SOS and EOS had same negative(positive) correlation with temperature(precipitation). Interestingly, based on two subperiods divided by change of climatic conditions, SOS and EOS still showed advancement during 1999-2015, but EOS showed delays during 1982-1998 which differed from the change during the whole study period. Next, SOS/EOS was controlled mainly by temperature (correlation coefficient: -0.53/0.18) during the first period but dominated by precipitation (correlation coefficient: 0.71/0.32) during the second period. Overall, this study highlights that the key climatic drivers on grassland vegetation phenology differ in different period and this should enlighten further studies on how climate factors affect grassland vegetation phenology at the seasonal or monthly scale.
