多元线性回归模型在区域地价评估中的应用——以澳大利亚悉尼“Vermont”项目为例

城市土地供应与投放攸关城市规划的有效实施,城市管理制度创新亟待新型的、多样化的土地估价技术方法的支持和应用。本文基于澳大利亚悉尼市Pitt Town的"Vermont"居住开发项目的土地出让数据,从土地物理属性的微观层面出发,尝试通过建立多元线性回归模型(MLRM:Multiple Linear Regression Model)来进行区域土地估价,为未来项目周边地区的开发提供决策参考。目前国内土地估价仍多以定性比较评估为主,本文深入探讨了MLRM方法在地价评估与预测中的应用,以期为国内相关领域提供借鉴和参考。

Using Gamma Emissions to Identify Cycles in the Lower Cambrian Monkton Formation (NW Vermont): Implications for Identifying Sea Level Variation on the Iapetus Margin

The Monkton Formation is described as a Lower Cambrian regressive sandstone unit containing shallowing-up cycles, called parasequences, which record tidal flat progradation. Spatial variation and limited outcrops of continuous stratigraphy have made it difficult to characterize how cycles change in architecture and thickness through the entirety of the Monkton Formation. This study seeks to identify stratigraphic trends in the parasequence architecture and thickness from the successful recognition of facies in the subsurface, information that will clarify how the sea level changes and impacts accommodation space. New geophysical data allow this research project to explore the stratigraphy of the Monkton at higher levels of resolution than previously achieved. Initial statistical study of gamma ray data from a well through the Monkton suggests that meter-scale parasequences are identifiable in geophysical logs. Using continuous gamma log data, this work identified clastic carbonate ratios from a 1034’ deep geothermal well drilled at Champlain College in Burlington, VT. Although cycles were identified in the gamma log, the spatial variation, complexity and variety of parasequence types within the Monkton made it difficult to correlate the sequences with specific environments or changes in sea level. To see if specific architectural elements of parasequences and lithologies could be characterized by gamma values, outcrops of the Monkton were surveyed containing both parasequences and lithologies that were useful paleobathymetric indicators. The survey determined gamma ray patterns and relative values of a common Monkton parasequence representing tidal flat progradation and a carbonate lithology indicating an abrupt sea level rise. Gamma data from a second well on the University of Vermont campus, along with accompanying borehole camera video, confirmed that the outcrop survey results could be useful in subsurface interpretations of the Monkton. Intervals representing the parasequences and carbonate lithologies were identified in the Champlain College Well and were combined with the UVM Fleming Well findings to create a composite stratigraphic section of the Monkton. The parasequences and lithologic trends identified in the composite section indicated that, over the entirety of the Monkton, accommodation space decreased. The decrease in accommodation space is interpreted to represent a change in the rate of sea level rise. The Monkton Formation deposition occurred in a transgressive systems tract with varying rates of sea level rise, which implied that the overlying Winooski Formation would represent highstand systems tract deposition.

Evaluating the process of mental health and primary care integration:The Vermont Integration Profile

Objective:We developed and tested a measure to identify level of primary care behavioral health integration.We produced a thirty item,six domain electronically delivered measure,and a total score.Methods:We generated a convenience sample of 137 survey responses,including 104 pri-mary care practices.We provided each practice a summary of their own data,and generated a data base of all submissions.We calculated descriptive statistics.Results:The mean total score was 56/100.The Vermont Integration Profile(VIP)discrimi-nated between types of practices in the direction hypothesized.Initial test retest reliability was good.Conclusion:The VIP demonstrated good feasibility and construct validity,initial reliability,low provider demand and good discrimination between types of practices.
