Population viability analysis(PVA)is a qulckly developing new technique and has become a central issue of conservation biology.It mainly probes into effects of extinction for small polulations by stochastic perturba-tions and its goal is to establish a minimum viable population that reduces risk of an extinction to an acceptable level.The stochastic perturbations can be classified into four kinds:demographic stochasticity,environmental stochasticity,natural catastrophes and genetic stochasticity.There are three approaches to determining MVP:theoretical models,simulation models and isldand biogeography method.The theoretical models mainly analysize effects of stochastilc perturbations on MVP under ideal or given conditions.The simulation models use computer to simulate the extinction processes for populations, and the island biogeography method analy - sizes distribution and survival of species on islands,and testifies theoretical models and simulation models. There are a great number of literatures that study behavior characteristics of demographic stochasticity,envi - ronmental stochasticity and natural catastrophes. But the relationships between genetic factors and population viability are not clearly known.The developmental trend of population viability analysis is to build a compre - hensive model that includes four kinds of stochasticity,widely to test PVA models,systematically to study genetic and ecological characteristics of target species and explore PVA's application in conservation practices.
