Determination method of regional development axis based on GIS & improved AHP with example of Shandong province

Taking Shandong province as an example, the paper put forward the determination method of regional development axis and their importance and levels based on pole-axis theory. Firstly, the writers selected four regional development axes according to the conditions of choosing regional development axis, and then analyzed the ranges of the 4 axes and the cities and towns in the ranges with the method of buffer analysis of GIS. Secondly, the writers calculated the importance of the four axes with the method of AHP, which had been improved by the principle component method. Finally, according the result of AHP, the four axes were classified into two types called the first and the second class development axis with the method of self-organizing competitive neural network. From above, we know that the importance and levels of regional development axis can be determined by the methods of buffer analysis of GIS, AHP and cluster analysis.
