    • Abstract
  • Ecological field characteristics of Alsophila spinulosa individuals in different sites in Guaxi A.spinulosa Nature Reserve of Fujian Province were analyzed and discussed by constructing the model of ecological field of A.spinulosa individual.The results indicated that Q5>Q6>Q4>Q3>Q8>Q7>Q2>Q1 was the order of the maximal values of ecological potential of average individuals of Alsophila spinulosa populations in 8 different sites.Ecological potential of small individual was low and large individual was high.The extinction form of ecological potential of average individual in the each site all trended to Gaussian distribution.The effective influencing distances of ecological field of average individuals in diffe-rent sites ranged from 0.058 m to 8.475 m,the effective influencing areas from 0.0036 m2 to 381.307 m2,and the order was Q5>Q6>Q4>Q3>Q8>Q7>Q2>Q1.
