RECONSTRUCTION OF LOCAL DYNAMICS IN PLANTS INTERFERENCE

摘要

Variability control is a key issue for farming, especially for precision farming. It is the first step to achieve the spatial management, to know the source of variability of filed properties such as yield distribution, weed distribution, soil properties. Our final goal is to built up the scheme of spatio-temporal management of weed-crop systems. 2-Dimensional Coupled Map Lattice (2D-CML) model is developed to describe spatio-temporal dynamics of the multiple competing plant spices. Lotka-Volterra model is employed as a fundamental function describe competition among spices. Local interference is also incorporated into the model among neighboring cells. Without any rule to govern a global pattern of the plants community, it generates a global pattern by a given local dynamics. This is recognized as a kind of emergence from complexity. We also develop the algorithm to identify the local dynamics of multiple competing plant competitions from spatio-temporal data.
