URBAN HEAT ISLAND AND URBAN HEALTH: EARLY AMERICAN PERSPECTIVES*

The nature and sources of early American understanding of an important form of human-induced climatic change, the urban heat island effect, are considered. Recognition and explanation of the phenomenon occured both earlier and more widely than is usually supposed. Interest stemmed not only from concerns that remain significant today, but from others that have been discarded, notably anticontagionist theories of the causation of disease.     

RESEARCH ON SYSTEM OF FLOOD DISASTER CONTROL AND REDUCTION SUPPORTED BY GIS IN MEDIUM AND SMALL BASINS

Southeast China coastal areas belong to subtropical monsoon climatic zone,thus easily affected by floods resulted from typhoons and rainstorm.Since the areas of river basins are small,rivers flood regulation capacities are low,and therefore flood hazard is grave.In the paper,taking the Yongjiang basin in southeast China as an example,the approaches and methods of geographic information system(GIS) applied to flood disaster control and reduction research on small basin are explred.On GIS help the rainfall-runoff calculation model and the river dchannel flood routing model are developed.And the evaluating flood submerged are and the damage assessment models are built supported by digit elevation models.Lastly the decision support system on GIS supported for flood control in research basin has been set up.This greatly improves flood-proofing decision-making capacities in river basin,and provides valuable information and a mode for flood prevention and reduction in the medium and small basin .Meanwhile,the research indicates that technologies of GIS provide a powerful tool for flood disaster control.     

DYNAMICAYOUT ADJUSTMENT AND NAVIGATION FOR ENTERPRISE GIS BASED ON OBJECT MARK RECOGNITION

In this paper a new method is developed to make a dynamic layout adjustemnt and navigation for enter-prise Geographic Information System(GIS) based on object mark recognition.The extraction of object mark images is based on some morphological structural patterns,which are described by morphological structural points,contour prolpety,and other geometrical data in a binary image of enterprise geographic information map.Some pre-processing methods,contour smooth following,linearization and extraction patterns of structural points,are introduced If any special object is selected to make a decision is a GIS map ,the all information around it will be obtained.That is ,we need to investigate similar object enterprises around selected region to analyse whether it is necessary for establishing the object enterprise at that place.To further navigate GIS map,we need to move from one region to another,Each time a region is formed and displayed based on the user‘s focus,If a focus point of a map is selected,in terms of extracted object mark image,a dynamic layout and navigation diagram is constructed.When the user changes the focus (I.e.click a node in the navigation mode),a new sub-diagram is formed by dropping old nodes and adding new nodes,The prototype system provides effective interfaces that support GIS image navigation,detailed local image/map viewing,and enterprise information browsing.
