本课题从三个相互联系的专题(即不同生物气候区荒漠化景观的结构特征、荒漠化驱动因素及其作用机理、典型荒漠化地区荒漠化发生与发展的景观空间动力学模型)入手,在深入研究荒漠化景观结构特征与过程的关系及其稳定性,不同时空尺度的荒漠化过程驱动力及其在荒漠化过程中所占比重、表现形式及作用机制,地表风蚀临界条件的确定等内容的基础上,虽未建立荒漠化景观空间动力学模型,但在沙漠化概念,末次间冰期以来沙漠化过程时间序列和特征冷暖时期沙漠、沙地空间分布格局,现代沙漠化过程中自然因素和人文因素的作用、贡献率、沙漠化土地对气候的反馈作用以及风蚀临界值,沙粒跃移轨迹参数和能量分布,我国沙漠化防治思路和对策,沙尘暴区划和沙尘暴指数等方面取得了重要进展。

Low magnetic susceptibility, low CaCO3, low organic carbon concentration, low C/A (Chenopodiaceae/Artemisia) ratio, low Sr concentration and, hence, high Rb/Sr ratio in the lake sediments indicate a cold but moist climate during the global Little Ice Age in the Daihai area.

This is not surprising, given the closer proximity of Pengyang to the Asian inland dust sources; The average content of calcium carbonateis of Pengyang section is not only higher than that of central loess plateau, but also higher the west of Chinese Loess Plateau, which reflected Pengyang loess had been deposited by near Liupanshan\'s substances that contained more calcium carbonateis; The content of diffluent element of 10m depth in the section increased fast, which indicated that the modern eluviation and the leaching depth of loess may be stronger than our guess; The soil growth index can reflect the intensity of soil forming and the climatic changes; The "abrupt chang" of glacial and interglacial period was caused by strong soil-forming processes that enlarged the discrepancy of granularity between loess and paleosol. However, the magnetic susceptibility nearly cannot reflect the existence of S_8 and the magnetic susceptibility of S_7 is highest in the whole section, which is inconsistent with other studies that S_5 has the highest magnetic susceptibility.Thin-section examination shows that the micro-texture of the soil layers is divided into both cementing texture in S_7, S_5 and S_1, and granular texture in all others.

与其它剖面相比,彭阳剖面粒度总体上要比东部的洛川、西安,甚至西部的兰州、新疆东湾要粗;CaCO_3平均含量不仅高于黄土高原中部,也高于高原西部,反映出本剖面富含碳酸盐的六盘山近源沉积起到了很重要的作用;易溶元素含量在剖面10m处快速升高,淀积特征明显,反映出黄土受现代淋溶成土作用影响较大,黄土直立、疏松、多孔特性和高温与多雨组合的气候特点,使得元素淋溶、淀积的强度和深度超出了传统的认识和判断;烧失量与其它指标相比,不仅能区分冰期、间冰期;而且能够区分出次一级的冰阶、间冰阶,有较高的分辨率;土壤发育指数、红度能够反映土壤强度差异,是反映气候波动的较好指标;然而,磁化率不能反映古土壤S_8的存在,且S_7的磁化率在全剖面中最高,这与大多剖面S_5磁化率最高的特点不一致。4。

Although significant uncertainties remain about both the cause and the scale of the impact of these abrupt climatic events, there is growing general knowledge of change process in climate during the past 13 000 years based on the studies of some important rapid climatic oscillations, such as a cold and dry event near the middle of the last interglacial, Dansgaard-Oeschger cycles, Heinrich events and Younger Dryas event during the last glacial and some cooling events during the Holocene.

尽管末次间冰期以来这些数百年-千年时间尺度气候突变事件的成因和影响范围还存在明显的不确定性,但已从诸如末次间冰期(MIS 5e)中期的干冷事件、末次冰期的Dansgaard-Oeschger旋回、Heinrich事件和Younger Dryas事件以及发生在全新世冰后期的一些降温事件的研究中。获得对过去130ka来气候变化过程总体上的认识知理解。
