Новые возможности анализа факторов эрозии почв с использованием гис-технологий

Аннотация

In this paper we suggest a new approaches to the analysis of basin erosion, taking relief characteristics and soil erosion as an example. Method based on GIS-technology includes using of the altitude grid layer, data processing and relief classification by means of artificial citron networks. The results obtained show obvious advantages of the method in comparison with the traditional cartometric works and soil erosion analysis by elementary basins. Correlation between soil erosion and relief parameters grows significantly in comparison with the results of traditional statistic methods. The classes of erosion relief in Tatarstan were distinguished. By means of this method the prognostic model of soil erosion may be developed for the classification purposes and for the erosion hazard rating of lands. The rise of accuracy of prognosis in comparison with other statistic methods was calculated.
