摘要：Climate aggressiveness and rainfall erosivity. The climate aggressiveness defines the extent to which elements of climate, their variability and interdependence affect a component of bio-pedo-geomorphological or human system. However, most studies analyze rainfall erosivity, namely the ability of rains to generate a significant erosional impact. There are two categories of rainfall evaluation methods: direct methods, which require a large consumption of time, financial and material resources, and indirect methods, less precise, but with the advantage of higher accessibility of meteorological data and better suitability for regional studies. This approach focuses on indirect methods in a brief presentation and argues the need to revise and updating of some indicators consecrated in Romania (eco-pedological indicator 99), given the substantial accumulation of climatic data and modernization of techniques for computer and complex spatial analysis. The arguments are based on indirect calculation of rainfall erosivity in eastern Romania.
