南京市住宅价格时空分异格局及其影响因素分析——基于地理加权回归模型的实证研究

以2009-2017年南京市“一主三副”商品房社区为基本研究单元,运用GIS地统计分析中的普通Kriging插值法对“一主三副”住宅价格空间分布进行模拟和估计,并利用地理加权回归（GWR）模型探究社区属性、商业区位、交通区位、服务区位和景观区位等类型变量对住宅价格的影响规律。研究结果表明：①南京市房价总体上呈现主城向副城递减的中心外围模式,“一主三副”住宅价格空间结构呈现出同心圆和扇形融合的混合模型。②中心位势对主城住宅价格影响相对下降,对副城影响相对提升,交通位势表现出相反的趋势,住宅房龄、绿化环境对住宅价格的影响由主城向副城递减,山水景观的影响由长江沿岸向外围递减。③主副城住宅价格影响因素具有空间异质性,其中主城受距CBD距离、住宅建筑年代和绿化率的影响较大,而副城主要受距地铁站距离、距景观资源距离的影响。

Past or present? Differentiating California prehistoric native American remains from forensic cases: An empirical approach

The goal of this project is to provide additional data and statistical analyses for differentiating between prehistoric/historic Native American remains and modern forensic cases that may be potentially confusing. Forensic anthropologists often receive requests from local law enforcement to infer whether skeletal remains are of forensic or non‐forensic significance. Skeletal remains of non‐forensic significance are commonly of Native American ancestry, but the empirical methods common for determining Native American affinity from skeletal remains have not been established for California prehistoric/historic Native Americans. Therefore, forensic anthropologists working in California lack empirical methods for not only identifying prehistoric California Native American remains, but also differentiating them from modern/forensic populations whose skeletal attributes are similar. In particular, skeletal remains of Latin American US immigrants of indigenous origins are becoming more present in the forensic anthropological laboratory, and can exhibit the same suite of skeletal traits classically used to identify Native American affinity. In this article, we initiate an investigation into this issue by analyzing both craniometric and morphoscopic data using a range of statistical methods for differentiating prehistoric Northern California Native Americans from modern Guatemalan Maya. Our discriminant analyses results indicate that by using nine craniometric variables, group classification is 87% correct. In addition, seven morphoscopic variables can predict group classification correctly for 77% of the sample. The results suggest that it is possible to differentiate between our two samples. Such a method contributes to the efficient and empirical determination of temporal and geographic affinity, allowing for the repartriation of Native American remains to their tribes, as well as the accurate analysis of forensically significant remains.

交通路网中心性对土地利用强度的影响研究——以青岛市中心城区为例

采取青岛市交通路网矢量数据和 POI 数据，综合运用核密度估计法、地理加权回归模型和多中心性评价模型，从中心性角度解析了青岛市中心城区交通路网与土地利用强度的相关关系。研究表明：青岛市中心城区交通路网的临近中心性与直线中心性结构呈现“中心—外围”模式，中介中心性具有显著的点轴模式；商业、公共服务以及居住用地布局均呈现多中心结构；交通路网中心性与土地利用强度具有较强的相关性且相关关系具有空间异质性；商业用地和公共服务用地与交通路网中心性的相关性高于居住用地。研究揭示了交通路网与土地利用强度之间具有较强的依赖性，为城市规划提供可靠的理论依据，有助于进一步优化城市空间布局。
