摘要: Plant biodiversity is defined by the variety in all plant-taxonomic categories (species, genera, families, orders, etc.) and of ecosystems plant communities to which they belong (Wilson 1992). One may distinguish following levels biodiversity, according a hierarchy increasing spatial extent: α – diversity (number species present single community, or local richness); β (variation number along an environmental geographic gradient); γ relatively wide area, regional δ on continent). The study today constitutes principal theme conservation biology (Primack 2002; Blasi 2005; Poldini 2009) at center grand theoretical practical discussion about implications survival species. In this chapter we introduce briefly some aspects relative possibility mapping biodiversity.
