AbstractImplementation of conventional agriculture has led to major changes in the agricultural sector, in particular in terms of structural simplification of agro-ecosystems, which has caused directrepercussions on their biodiversity. Demolition of balances between agriculture and biodiversity has decreased self-retaining ability of agricultural systems. The more simplified biodiversity in agro-ecosystems, through management models, the less they are able to self-regulate and self-maintained. A careful administration, which increases the level of biodiversity of inland, strengthens relationships and increases the stability of agro-ecosystems. Use of bio-indicator, to assess the level of diversity and sustainability of agro-ecosystems, has been widely used in recent years in many countries. From the analysis, with some levels, in order to assess the biological complexity in agricultural systems, we show that organic agriculture systems plant biodiversity indicators at the level of plot, the farm level ecological infrastructures and other indicators of agro-environmental, we are the approximate value of farm sustainability indicators, in comparison with the conventional system, indicators result in very low levels, which shows the instabilityof these systems. This makes necessary interventions in their structural plan, in order to increase the level of biodiversity, sustainability and quality of agro-ecosystems. Research conducted aims at identifying thedifferences between different types of agro-ecosystems, in order to design sustainable agro-ecosystems.

Key words:  biodiversity, agro-ecosystem; biological complexity,  bio-indicators, sustainability.
