KEY WORDS: GIS, resources, management, pollution, disaster, analysis, decision support.
ABSTRACT:
Recently bioenvironmental damages are being happened by occurrence of wars and also pollutions due to construct
manufactures and huge power stations on the natural environment. On the other hand, the maintenance of valuable resources and
also recognition of pollution resources are included in the main responsible of the relevant organizations. Meanwhile, using of
modern and advanced technologies and facilities cause increasing speed and accurate in their investigations and analysis. GIS is a
sort of theses modern technologies with a high capabilities and functionalities in the context of spatial and statistical analysis and
also resource management. The evaluation project of bioenvironmental damages has been done to assess and analyze the density
of pollutions in Persian Gulf by GIS functions.
1. INTRODUCTON
The decrease of biological and non-biological resources will
face the world with a sudden disaster in few next years. The
reasons for the decreases vary from growth of population to
irregular usage of energy to global events like wars and
immigrations.
Thus resource management becomes more and more important
to prevent human beings from falling in the darkness of poverty
and lack of energy.
GIS as a powerful system with its versatile capabilities such as
spatial analysis, visualization, and spatial database management
helps managers with support for making best decisions about
natural resources and management of these resources (C. J.
Data, 1999).
Persian Gulf as a vital resource in the region contains a large
number of substances, materials and also a great deal of food.
Besides there are a lot of oil wells in Persian Gulf that makes
the gulf a strategic arca.
Due to occurrence of many war disasters around Persian Gulf
in recent decades, it seems sensible to study about the effects of
wars on the pollution of the gulf and also elimination of
resources.
In order to reach the aim many studies about the situation of
living creatures have been made and a lot of observations about
materials and substances have been collected.
Data about living creatures like fishes and planktons, and
materials like carbonates and sulfates have been gathered in
forty five stations.
Collected data were categorized into biological and non-
biological terms. These collections have been repeated for four
seasons of year and for each station sixteen layers of data have
been observed.
Capabilities of Geospatial Information Systems give a powerful
hand for analyzing each data layer and displaying results as
charts, diagrams, and maps.

Consequently, the decreases in resources of any kind were
obvious through results, thanks to GIS statistical and spatial
analysis.
2. SPATIAL ANALYSIS
Even where nongraphic data has been computerized, the
researcher may still have to comb through sheets of computer
printouts while visually comparing the data with the maps. A
GIS provides the researchers with powerful automated tools to
answer these questions. These tools make it much easier to
analyze the data for special studies and reports. In fact, new
types of analysis that were not feasible before are now possible.
The GIS can quickly search through map data, looking for
features with certain characteristics, or inspecting spatial
relationships among features. Moreover, graphic data and
attribute data are explicitly linked. Thus, the GIS user can
search for map data using attribute data as a creation, and vice
versa (George, 2001).
The GIS can automatically and quickly answer requested
questions, but with traditional maps, these questions would
require a search through real files, follow by a visual review of
other maps, and also spatial analysis which is one of GIS
capabilities can be done on digital maps.
The spatial analysis is a tool for helping researchers discover
and understand spatial relationships in their data. This discovery
and understanding can be as simple as viewing and querying
their data or as complex as creating an integrated custom
application.
The main component of the spatial analysis is the grid theme.
The grid theme is the raster equivalent of the feature theme. The
Spatial Analysis also presents generic spatial analysis
functionality on grid and feature themes that is added to special
software.
With the spatial analysis, following functions will be able to
perform in GIS software: interpolate grid, find distance, assign
proximity, calculate density, reclassify, create contour, derive
slope, and derive aspect. Much more functionality is accessible
