KEY WORDS: important geographical elements, statistics, spatial analysis
ABSTRACT:
This paper base on the spatial data, discuss how to searching for the disciplinarian of basin’s residential circs, traffic lines, stream
nets and soil conditions such important geographical elements’ spatial distributing in the analysis of spatial information technology,
aim to through analysis the correlation data, depict the important geographical elements’ spatial distribution pattern, distill their
distribution quantitative and molar disciplinarians, so as to offer references to the international rivers’ exploiture and utilizing
programming, analysis and compositive evaluation.
1. INTRODUCTION
The World Wide Fund for Nature, which Headquartered is in
Switzerland, press release a report titled ((Ten rivers which
facing the most serious danger in the world)) on March 20, 2007.
The report noted, for the infection of climate changing,
pollution and other factors effective, some of the world's major
rivers are facing increasingly serious danger of drying up. This
report release before the "World Water Day" on the March 22,
listed 10 rivers which facing the most serious threat of drying
up, including Asia's Mekong - Lancang River, SALWEEN-Nu
River, the Yangtze River, the Ganges River and the Indian
River, the Danube in Europe, South America's Rio de la Plata,
North America's Rio Grande River, the Nile in Africa,
Australia's River Murray-Darling River.
Freshwater rivers are the main source of human being’s
limnetic requirement, because of the mismanagement and lack
of adequate protection, humanity will be faced with serious
limnetic scarcity crisis. Pollution, global warming, illegally
built dam and such phenomena on the spread, inducing several
representative rivers on the earth in the coming decades facing
severe crisis of survival. Therefore, we should protect the river
as part of the national security, people's health and economic
achievements, potentiate river protection, establish evaluation
model, accelerate compositive analysis and evaluation of the
international rivers, provide scientific basis to the
decision-making of drainage areas.
International rivers are the important compositive proportion of
our national water resource. Our nation’s Yun Nan, Xin Jiang,
Xi Zang and other 7 provinces, municipalities altogether share
international river over than 100 streams, international rivers’
utilization and distribution equitable and reasonable base on the
esteeming “domain integrity” and “domain sovereignty”,
process nations compact cooperate. Besides, it consanguineous
interfix with basin’s economy cooperate, community
development and region’s peaceful and stabilization. Therefore,
it is a compositive and complicated problem bestraddle on
subjects and frontiers.
Progressing logical analysis and layout of the basin’s abundant
resource is the foundation of the environment, economy,
society harmonious evolutive. Through spatial analysis, spatial
statistics such methods gain the residential circs, traffic lines,
river nets, soil conditions and such important geographical
elements’ spatial distribution information along different
altitudes, different admin-districts, different distances of the
river bank and different anabranches, analysis their spatial
distribution disciplinarians, meanwhile, combine local practical
complexion, macroscopical considering the rationality of city
planning is essential and significative.
2. RESEARCH ON STATISTICS AND SPATIAL
ANALYSIS METHODS OF THE CONVENTIONAL
GEOGRAPHICAL ELEMENTS
Through the statistics and analysis on the map measure and
configuration survey, study on objects’ distribution and
relationship, gain average, maximum, minimum, and etc value,
so as to consider them as a collection investigate objects’
quantity characteristics; besides, analysis variables’ spatial
characteristics, quest for the distribution disciplines of basin’s
important geographical elements.
2.1 Through calculate the measurement and
configuration indexes, statistic and analyze basin’s
important geographical elements.
