This study was conducted to evaluate the influences of environmental change on rice ecosystem biota through establishment of real time monitoring system and development of protocol for fluctuation of biota community monitoring. The scope of the study range was influence of environmental change on plant growth, natural enemy community and aquatic invertebrates in rice ecosystem. Disturbance of agricultural ecosystem by temperature raise was also analysed mathmatically.
Part 1 : Influence of environmental change on plant growth in rice ecosystem
Survey sites, Jeju, Mokpo, Jeonju, Icheon and Cheolweon provinces were selected by cluster analysis using warmth index, coolness index and rainfall data. Flora of rice ecosystem was identified as 166 species of 128 genera belongibg to 49 families. Among them, 37 species (Monochoria korsakowii, Aneilema keisak, Eleocharis kuroguwai and so on) were founded in paddy field, 140 species in levee (Digitaria ciliaris, Humulus scandens, Artemisia princeps and so on) and 11 species (Alopecurus aequalis, Centipeda minima, Oenothera odorata and so on) were commonly founded in both sites. Twelve invasive plant species such as Rumex crispus, Bidens frondosa, Dactylis glomerata were also founded in rice ecosystem. It is efficient to monitor 12 plant species such as Stellaria alsine, Capsella bursa-pastoris, Trigonotis peduncularis which were widely distributed for the comparison of plant phenology.
