Geographia Technica, Special Issue, 2010, pp. 47 - 51 MICRO-SCALE GEOSTATISTICAL ANALYSIS OF THE LEVEL OF DEVELOPMENT. CASE STUDY: MOUNTAINOUS AND SUBCARPATHIAN AREA OF IALOMITA HYDROGRAPHIC BASINIoan IANOS, Alexandru I. PETRISORABSTRACT: Researches concerning territorial differentiation of the level of development usually focus
on the macro-scale (counties and regions). This study employs similar analyses at the
micro-scale level using administrative-territorial units, i.e. circa 40 communes covering the
mountainous and sub-Carpathian space of an average sized hydrographic basin. The
algorithm uses data consisting of selected indicators referring to the density of population,
its dynamics and migratory increase, population aged over 65, natality, unemployment,
share of population working in agriculture, number of people who completed high school
education, the number of physicians per 1000 people, and inhabited area per person (square
meters). Data are analyzed using factor analysis to build an aggregated index of
development. Consequently, spatial prediction via ordinary kriging is used to determine its
spatial distribution. The results indicate that there are two ‘rich’ zones, one in the
mountainous region and another adjacent to the plain area, while the poorer ones range in
between. Their spatial distribution is perturbed by major communication routes and
differentiated accessibility. |
