- Аннотация: The major task of the research is to work out a method of imitation invasion plant population using lattice model. This modeling approach (Komarov et al., 2003) allows us to imitate spatial distributed plants population, as the fixedness of plants, their spatially explicit positions and interaction with the nearest neighbors, being the main characteristics of a plant distribution, play a significant role in the population development. A simulated model of invasion herbal plants population into bare territoiy was described in previous paper (Mikhailova, Bogdanova, 2006). We explored influence of vegetative overgrowth geometry (patterns) and the fhictiflcation features on invasion rates of the population of three nemoral herbs species — Aegopodium podagraria, Asarum eurtgtaeum, Stellaria holostea. The major dissimilarity of these tree species, is the type and rate of vegetative diffusion. The corresponding data was collected in the small-leaved forests of Nerusso-Desnjanskoe Polesje (Nerussa-Desna marshy woodlands) in the south-east of the Bijansk Region (Russia). In this paper we introduce effect of heterogeneity of territory under invasion into our simulation model. We treated heterogeneity of territoiy as a presence of busy cells prevented from sprout propagation and seed germination. One can observed such situation in the field, where invasion plants population introduces in the present coenosis. The main goal of the investigation is to examine influence of territory heterogeneity on dynamic of modeling population. We have found a set of critical probabilities of busy cells being ^>cciflc for the species under investigation with various scenarios. The critical probability is the maximal percent of № y cells for invasion going on. It has been shown in the paper, that the structure of population geometry is determined by probability of initial heterogeneity of territory; rate of cells leaving by sprouts, i.e. lifetime of sprouts; presence of seed germination; length and direction of creeping roots.
