This paper introduces an internet GIS for historical regional statistics developed by the Laboratory of Spatial Information Science, Doctoral Program in Geoenvironmental Sciences, University of Tsukuba. The paper discusses the objectives
of this project, the available data, its scope and features, and some of the prospects and challenges as an online geospatial database facility of historical statistics of Japan since the Meiji period.
Analysis of fire events and controlling factors in eastern India using spatial scan and multivariate statistics
statistic that quantifies hotspot areas of fire risk has been used to identify statistically significant fire clusters during the ten-year time period. To assess the causative factors of fires, topographic, vegetation, climatic, anthropogenic
and accessibility factors were used in a multivariate statistical framework. Results suggested a clear variation in hotspots of fire occurences among districts.
Statistical-empirical modelling of mountain permafrost distribution in the Abisko region, sub-Arctic northern Sweden
Climatic change ; Model ; Mountain ; Periglacial features ; Permafrost ; Regression analysis ; Soil temperature ; Spatial distribution ; Statistics ; Sweden
The aim of this study is to quantify lower permafrost limits in the Abisko region by means of independent proxy data (BTS) and statistical analysis. The results serve as a basis for evaluation of climate and environment permafrost relations

GIS-based landslide susceptibility mapping using analytical hierarchy process and bivariate statistics in Ardesen (Turkey) : comparisons of results and confirmations
In this study, the analytical hierarchy process (AHP), the statistical index (Wi), and weighting factor (Wf) methods were used to produce and later compare 3 susceptibility maps. For this purpose, thematic layers including landslide inventory

The main aim of the paper is to analyse the demographic situation (vital statistics and migration) in The Pomorskie Voivodeship in 2006. In some cases the analysed period was 2000-2006. Since the situation in the region is not uniform, the analysis
The paper presents a demographic analysis of Polish voivodships, with a focus on Łódzkie and Świętokrzyskie. The basis for the work was provided by statistics from the Central Statistical Office of Poland (e.g. as regards the population of Poland
in the years 2002-2007 and the Polish population forecast formulated in 2008). Despite their central locations within Poland, Łódzkie and Świętokrzyskie voivodships have experienced a decline in their natural increases per 1000 head of population since 2002
(at rates of 3.2 and - 1.4‰ respectively up to 2007). This paper therefore seeks to explain the natural decreases in question, by reference to a dimensional analysis of population, structure as regards age, other vital statistics and data on migrations
This paper is based on the hypothesis that the official statistical data does not reflect actual succession status on mountain farms in Slovenia and also on Slovene farms in general, since the census criteria defining succession are still incomplete
. With the purpose of confirming our assumption, we formulated more accurate criteria and also determined as to what is the real status of succession on mountain farms in Slovenia. It has proved to be more favourable, than it is presented by the official statistics
This paper focuses on the urban biogeographical study of tree quality with regard to habitat conditions that vary mainly by land cover. Statistical analysis, including logistic regression, was used to test the hypothesis that tree performance
performance was related to land cover. Exotic and evergreen species grew better than indigenous and deciduous, offering hints on species-habitat matching. Detailed field and statistical analyses could yield tree-environment information to enhance urban

Based on historical documents, modern survey and statistics, the trend and main process of forest dynamics are recognized. The forest area and forest coverage rates for each province of China from 1700 to 1949 are estimated backward by every 50
The AA. developed statistical models of colluvium and shallow-groundwater distributions to aid landslide hazard assessments. The models were developed using a geographic information system, digital geologic maps, digital topography, subsurface
exploration results, the groundwater flow modeling VS2DI and regression analyses. Input to the colluvium model includes slope, distance to a hillslope-crest escarpment, and escarpment slope and height. The AA. developed different statistical relations
