Study on the spatial pattern of rainfall erosivity based on geostatistics in Hebei Province, China

Abstract: The objective of this article was to study the spatial distribution pattern of rainfall erosivity. The precipitation data at each climatological station in Hebei Province, China were collected and analyzed and modeled with SPSS and ArcGIS. A simple model of estimating rainfall erosivity was developed based on the weather station data. Also, the annual average rainfall erosivity was calculated with this model. The predicted errors, statistical feature values and prediction maps obtained by using different inter… Show more

“…In the Tibet Plateau, the mean annual erosivity was generally lower than 500 MJ mm ha − 1 h − 1 , similar to the results of Zhang et al (2003). Annual rainfall erosivity varied from 679 to 2428 MJ mm ha −1 h −1 in Hebei province, showing a rather big difference from the values between 930 and 1667 MJ mm ha − 1 h − 1 calculated by the revised Fournier index during 1961-2000 (Men et al, 2008). The spatial variation of rainfall erosivity was largely determined by the spatial distribution of annual rainfall.…”

“…Segundo Wischmeier & Smith (1978), são necessários pelo menos 20 anos de informações para se ter um valor de erosividade da chuva representativo de uma; entretanto e em função da escassez de informações de estações pluviográficas no Brasil, vários pesquisadores vêm utilizando correlações entre a erosividade, determinadas em registros pluviográficos detalhados, para determinar a erosividade por meio de séries pluviométricas históricas para diversas regiões (Silva, 2004;Gonçalves et al, 2006;Mello et al, 2007;Montebeller et al, 2007;Men et al, 2008;Almeida, 2009;Silva et al, 2010;Arai et al, 2010). Desta forma, no presente trabalho os dados pluviográficos serão utilizados para estabelecer e descrever matematicamente a relação entre o índice de erosividade da chuva (EI 30 ) e dados pluviométicos (precipitação e coeficiente de chuva) mensais.…”
