摘要：
The Gibbs model and the pseudo-likelihood estimation method are applied to study interactions between trees of pine and spruce forests in the southern half of Finland. The coordinates of trees have been measured on small sample plots in the original data. Only some trees from the plots are needed in parameter estimation through field measurements.
