Handeliodendron bodinieri is an epibiotic single-species of plant unique to China in limestone regions.Because of destructive human activities,its peculiar habitat and its own characteristic,this rare species is endangered,and hence it has been listed as one of the first-level preservation plant species under state protection.Handeliodendron bodinieri population in Mulun Nature Reserve was investigated based on sampling plot and sampling line in order to clarify its population structure,dynamic character and distribution pattern.Size structure and height structure of Handeliodendron bodinieri population were analyzed.Point pattern analysis was applied and the spatial characteristics were described effectively by Ripley s K(d) function in this paper.The results showed that population of Handeliodendron bodinieri was declining due to lack of its seedlings,and distribution pattern of population was mainly random.Distribution pattern of Handeliodendron bodinieri population was primarily affected by the factors including its reproduction characteristics,habitat feature of limestone region,intraspecific and interspecific competition and so on.
