The article discusses approaches to assessing the sustainability of herbaceous vegetation on the slopes of exogenous origin. Heterogeneous ecosystem slopes on environmental indicators and specificity characterized micro-and macrozones within the same territory, and therefore difficult to assess sustainability. Due to lack of criteria for transition from quantitative to qualitative changes in the system under study is the definition of the boundaries between communities within the territory of the slope is sometimes difficult. Indicators generality of occurrence and species diversity of plants vary depending on the location of vegetation on the slope. In the context of the complexity of the dynamic processes altitude position and orientation of the slope proposed integral indicator assessing the sustainability phytocenosis slopes obtained from the study of occurrence, common species and species diversity of herbaceous vegetation. Analysis of the dynamics of species diversity, and similarity of species occurrence of species of herbaceous vegetation on the slopes of exogenous type led to the conclusion that at the value of the integral sustainability index 0.6 and up slopes covered by vegetation are relatively stable.
