驳施雅风“冰臼”“负球状风化”成因论

施雅风院士最近撰文指出笔者等近年来在中国东部发现的若干"冰臼"并非冰川遗迹,而是花岗岩经"负球状风化"而成。然而,他所谓的"负球状风化说"与当地的气候环境条件和客观存在的事实完全相悖。冰臼是地表负地形之一,现今是"堆积区"而不是"侵蚀区",以现代常见的侵蚀作用产生冰臼的所谓"风说"、"壶说"、"风雨说"、"差异风化说"、"负球状风化"等,都是不可能的。这些假说是对过去业己形成冰臼群进行不同成因推断,是对冰臼群成因的最大误解。冰臼只能由大量冰川融水沿冰川裂隙自上向下,以滴水穿石的方式形成滚流水钻,强烈冲击下伏基岩产生。从河流流水动力学特点上看,急流旋涡主要产生水平力为主,而冰臼的形成主要是垂直力才有可能产生,因此河流流水也是无法产生冰臼的。     

基于近底原位观测的小尺度海底沙波地形小波分解

浅海海床发育着不同尺度的活动性砂体,在大型活动性砂体上常叠加发育着大量小尺度沙波(纹),分析这些小尺度沙波(纹)有助于揭示活动性砂体的成因机制。但它们的尺度较小,常规分析方法往往将其作为高频噪声滤除,难以对该尺度海底沙波(纹)进行分离量化研究。为了解决这个问题,本文设计并实现了一种基于小波分析的小尺度海底沙波地形分解方法,并以台湾浅滩典型区域的高精度近底原位观测数据为例,实现了小尺度海底沙波地形的分解和定量分析,分解出背景地形、小型沙波和沙波纹(波长小于0.6 m)3种地貌类型。本文提出的小尺度海底沙波地形分解量化方法,可广泛应用于浅海高活动性地貌发育演化和海底边界层沉积动力过程研究,对评估海洋工程的稳定性也具有一定的实用价值。

Spectacular Macau: Visioning futures for a World Heritage City

This paper examines the conflicting sentiments generated by Macau’s recent developments and how these dynamics have helped galvanize particular visions among Macau’s residents holding different possessive relationships to the city. More specifically, it explores these processes through the simultaneous construction of two incongruent landscapes: a fantasyland of gaming and leisure propelled by the liberalization of the casino industry, and a ‘historic city of culture’ exemplified by Macau’s newly acquired UNESCO World Heritage City status. Building on Debord’s conception of the dialectic of the spectacle, this paper illustrates how the growing support for heritage conservation in Macau has been propelled by a shared anxiety over the phenomenal changes brought by an expanding casino industry and concomitant erosion of Macau’s cultural identity. Through extensive interviews with local architects, conservation experts and activists, I elucidate how the designation of Macau as a World Heritage City has helped consolidate particular sets of moral claims around heritage and culture as well as introduced new commodifications of the environment that cannot be easily delinked from other spaces of the ‘spectacle city’.

Web-based application for estimating water quality impacts due to environmental dredging

A Web-based dredge plume simulation software has been developed for estimating sediment transport and contaminant release from dredging operations. This application software comprises a near-field source model and far-field sediment transport model, combined with the settling analysis of flocculent particles. It is designed to run on all computing platforms with a standard Web browser and is accessible over the Internet. This paper describes its internal software structures and the major features of the application software. In addition, an example application of sediment transport in the Savannah River, GA, is included to illustrate typical input and output screens and to demonstrate the accuracy of the model. The water quality assessment software developed herein will greatly enhance the ability of the predictive tool for estimating sediment transport and resuspension during dredging operations.

诠释地球生命力报告:1998—2010

《地球生命力报告》应用地球生命力指数、生态足迹和水足迹3个指标描绘了全球自然生态系统的状况与变化趋势,以及在经济发展过程中可再生资源可持续利用的程度。本文在简要解读1998年至2010年的全部8期报告核心内容的基础上,认为人类对生态系统的衰退尚没有给予足够的重视,人们的生活方式应有所改变。只有认识到保护自然是为了人类自身的健康、财富和福祉,而不是维护生物多样性本身和只有意识到自然在维护人类健康和生活中所起的核心作用时,人类才能更好地维护我们生活的这个星球,因为我们只有一个地球。
