地壳垂直形变场的综合逼近模型

针对地壳垂直形变受多力源影响，单一逼近模型难以准确逼近地壳形变场的问题，提出了两步逼近综合模型和加权综合逼近模型，给出了模型应用实例并进行了验证。结果表明，综合逼近模型具有一定的理论研究和实际应用价值。

东海黑潮变异若干问题的初步分析

黑潮是世界上著名的强流，它是影响黄海、东海陆架环流的主要流系。黑潮的变异，不仅对几乎整个东海及其邻近海域的水文状况的变化有巨大的影响，而且对东亚气候的变迁也有显著的影响。因此，黑潮变异问题的研究，对于大洋环流及其动力学的研究以及黄海、东海海洋水文状况、东亚气候变迁的预测等，均有重要的意义。 关于东海黑潮的变异问题，在管秉贤(1979，1981，1982)及管秉贤等(1979)的论文中，己作了不少分析；但由于资料系列长度的限制，这些分析工作主要是定性的。诚然，即使在目前，要获得关于东海黑潮变异特征的定量关系也决非易事。有鉴于此，本文想在尽可能收集更多资料的基础上，对东海黑潮变异的若干问题作进一步分析，以期获得若干定量的概念。     

The Search for Boundaries on Maps: Color Processing and Map Pattern Effects

This paper presents a model which combines three of the parameters of the "Swiss manner" of relief representation with the Yoeli method of analytical hill-shading.

The model consists of various computational and graphic procedures that are intended to imitate by computer the complex hand-shading process. The first two procedures adjust the light source vertically and horizontally to the local relief forms. The adjustments avoid the disappearance of edges in unfavorable positions and exaggeration of others, and they utilize digitized data of the network of ridges and ravines. A third algorithm deals with "atmospheric perspective," the phenomenon of diminished value contrast in low lands and enhanced contrast in upper areas. This procedure also allows a general change in tonal value as a function of altitude. Other procedures deal with multicolor relief shading techniques, small-scale generalization, and selected reproduction problems.

Graphic output has been performed on a modified printer (IBM 1443) and a CRT raster recorder.     

Maps and Mapping Technologies of the Persian Gulf War

Assessing the recent Persian Gulf War from a cartographic standpoint is now possible. Unlike in previous wars, which established new technologies for postwar cartographic exploitation, the gulf war is unique in having presented a proving ground for electronic cartographic technology. An analysis is given of map coverage of the war by the media, especially magazines and newspapers, and from a military perspective. From a cartographic standpoint, the winners in the war include hand-held Global Positioning System (GPS) technology, geographic information systems (GIS), workstation-based image processing and cartographic map-production systems, and radar imaging from aircraft. More fully exploiting and building on the success of these technologies in peacetime seems to be a clear mandate for academic and professional cartography.     

Using Building Permits to Monitor Disaster Recovery: A Spatio-Temporal Case Study of Coastal Mississippi Following Hurricane Katrina

The pace of disaster recovery varies considerably from one place to another. Even when places suffer impacts from the same event, recovery studies often lack the spatial and temporal resolution to fully understand such local variability in the recovery process and patterns. This paper discusses the novel use of building permits and a spatial scan statistic to identify the spatial and temporal dimensions of recovery in coastal Mississippi following Hurricane Katrina. Our work identifies significant space-time clusters of recovery activity and indicates that the amount of damage experienced and the amount of pre-event housing strongly influence the timing and location of building permit clusters. This analytical method and the use of publicly available data are valuable for a better understanding of long-term recovery processes.     

The Spatial Data Transfer Standard: A Catalyst for Change

The Spatial Data Transfer Standard (SOTS), as a standard, is somewhat of a paradox. Standards help to establish order and promote stability. As such, SDTS serves both as a standard and a catalyst for change. Beyond being the first major geographic information systems(GIS) standard, SOTS has invoked—and continues to invoke—significant changes throughout federal organizations and other' organizations that interact with them. The changes inspired by SDTS focus attention on the importance of GIS standards. This importance, in turn, is the underlying force in creating a GIS standards infrastructure. The infrastructure provides a mechanism/process for developing, approving, and coordinating GIS standards in the federal, national, and international communities.     

伽师地震与区域断层活动研究

利用GPS、连续倾斜和地震活动性资料分析了伽师地区构造活动的特点和伽师强震群的动力背景，结果表明：在印度洋板块的挤压下，塔里木盆地的右旋腑冲运动是造成南天山区地震活动的主要原因；1996年3月19日伽师阿图什6．7级地震，强烈地影响了该地区块体由向西南倾斜转向北向倾斜，并可能成为诱伽师地区强震群活动的主要动力因素，利用1998年和1999年对该地区GPS测量的结果，给出了该地区断层活动的水平。
