为对一批出土的西周至东汉毛织品进行羊毛品种及编织方法进行研究,以鉴定羊毛品种和确定相关产地,应用扫描电镜分析羊毛毛纤维的组织结构、形态、纤维类型、细度,鉴定了羊毛品种。检验说明,扎滚鲁克和山普拉墓地出土毛织物主要是用新疆羊的羊毛织制的。     

三江源区生态移民的价值测算与补偿机制研究

三江源区在我国乃至世界占有极其重要的生态地位。随着三江源区生态保护与建设项目的顺利实施,作为该项目十大工程之一的生态移民建设已经取得了阶段性的成绩,但在推进生态移民工作中存在的问题也日渐显现。要着力解决这些问题,关键在于理清并建立该区域生态环境的价值测算与补偿机制。     

空港经济产业布局模式及规划引导研究——以广州白云国际机场为例

从产业布局的角度探讨了国内近年比较热门的空港经济现象。首先从与机场最直接相关的人、物、资金和信息四大要素入手,剖析了空港经济主要产业类型及其特征,并分析了空港经济总体区位及其演变过程。在此基础上总结分析空港经济产业具有与发展阶段相吻合的增长极、点轴和网络三种布局模式,指出国内备受推崇的圈层布局是发展阶段不明确的理想模式,并尝试采用地理信息系统空间分析方法对产业布局的区位进行叠加分析。最后以广州新白云机场为例,探讨了周围花都区和白云区空港经济产业布局规划方案和措施。     

甘肃省城市经济辐射区及其经济协作区研究

文章选择了断裂点模型作为定量衡量的方法,应用断裂点公式、场强公式和辐射半径公式,以城市规模和城市距离为起点,计算出断裂点位置及其场强,并选择边界场强计算出了甘肃省14个主要城市的经济辐射半径。依据这一定量化的辐射范围,分析了甘肃省区域内点辐射和线辐射的特点,进而为城市经济协作区的划分、城市化战略以及非均衡发展战略的制定提供了一定的参考。     

国家级新区的空间生产与治理尺度建构

国家级新区是近年来备受瞩目的新国家空间类型。首先,论文从新国家空间的理论视角出发,认为国家级新区是我国新时期国家空间选择偏好从城市内部空间转变为城市群体空间的产物,是国家为参与全球城市竞争和承接全球产业转移而在城市-区域尺度上构建的新地域组织。其次,论文研究了国家级新区的空间生产,发现其在微观尺度上具有多尺度行政区跨界联合的特征,并且表现出自上而下和自下而上相结合的机制。然后,基于空间生产与尺度重组的密切联系,论文同时研究了国家级新区治理建构的情况。通过分析不同类型的国家级新区空间治理结构,发现影响国家级新区尺度重组进程的关键因素,是新尺度与原有行政区划的耦合程度。最后,在上述研究的基础上,论文对国家级新区未来治理改革提出了政策建议。     

祥云地区出土铜器pXRF成分分析——昆明夷铜器工艺类型初探

为探究滇西地区青铜文化及相关铜器的制作技术,本研究使用便携式X射线荧光光谱(p XRF)对滇西祥云县大波那墓地、检村石棺墓和红土坡古墓群出土357件铜器进行了成分分析。结果表明,p XRF可在无损、原位的情况下,基本做到铜器合金成分的定量分析。铜器材质均以红铜和锡青铜为主,铅锡青铜和砷铜居少量。三处墓地铜器Sn、Pb配比模式高度一致。铜矛、铜剑等兵器中出现少量高锡青铜。这些现象反映出祥云地区各时期铜器的制作工艺高度一致,可称之为昆明夷铜器工艺类型。大波那墓地铜器基本不含铁,其余墓地存在较多高铁铜器,大波那地区的先民应该采用了不同的冶炼技术。砷铜全部出自红土坡古墓群,初步推测晚期墓葬出现的砷铜乃至砷铜工艺很可能是沿着"半月形文化传播带"由西北地区传入祥云地区的。     

Testing Area‐Scale Fractal Complexity (Asfc) and Laser Scanning Confocal Microscopy (LSCM) to Document and Discriminate Microwear on Experimental Quartzite Scrapers

Few microwear studies have been conducted on tools made from quartzite. Most rely on visual observation of microwear features using optical light microscopes and scanning electron microscopes. Quantification of microwear on quartzite tools is extremely rare, even though numerous methods to mathematically document surface roughness have been applied to other silicate tools. In this paper, laser scanning confocal microscopy (LSCM) was used to document surface roughness on four experimental scrapers made from two different subtypes of Mistassini quartzite that were used on either fresh or dry deer hide. Surface roughness data were analysed using area‐scale fractal complexity (Asfc). The results of this test case indicate that Asfc can effectively discriminate between the unused and used regions on the quartzite tools based on surface roughness, and that it can also discriminate between surface roughness produced by working dry versus fresh hides. Differences in the subtypes of Mistassini quartzite did affect surface roughness, but not significantly enough to prevent discrimination of the dry and fresh hide‐working tools. Although the use of the Asfc parameter for lithic microwear analysis requires further testing, these first results suggest it could be a reliable technique to mathematically document and discriminate wear patterns on archaeological quartzite tools.     

Terra incognita: terrestrial LiDAR documentation of Mound A at Kolomoki (9ER1)

ABSTRACT

The manifest representation of space and place is essential to good archaeology. Our ability to document and relate these concepts, projected into the past and reflected in the present, has increased tremendously with the expansion and availability of technology. We present recent efforts to further document a well-known place in the cultural landscape: the Kolomoki site in southwestern Georgia, occupied primarily during the Middle and Late Woodland periods. Specifically, we summarize older investigations of Mound A, then present the results of recent terrestrial LiDAR documentation. Our work substantiates the claim that Mound A was the largest Woodland-period mound in Eastern North America in terms of overall volume.     

The Formative Period on the south coast of Peru: A critical review

Previous and current fieldwork has generated a significant body of data on the occupation of the south coast of Peru during the Formative Period (ca. 3800-2200 B.P.). These data are placed in a synthetic framework and evaluated and compared to the trajectory of cultural development in the better studied regions of the Central Andes. Critical review of this panorama necessitates consideration of the relative chronological framework and definition of the Formative Period, the parameters and validity of the south coast as a culture area, contacts south coast societies sustained with other Central Andean regions, and the role of monumental architecture in the rise of complex society.
