Abstract

Biogeography is the study of the distribution of biodiversity over space and time. We report the development of a prototype database that maps of microbial diversity in the context of the geochemical and geological environment and geographic location. It aims to reveal where organisms live, and at what abundance in nation wide. Microbial data collected from agricultural land during 1999 to 2007 were categorized for mapping with ArcGIS program. Distribution maps of bacteria, fungi, Bacillus and gram negative bacteria of agricultural land showed different patterns from each other. Microbial biomass content investigated in year of 2007 was higher than in 1999.

농경지 토양미생물상의 생물지리학적으로 특성을 보고자 우리나라 농경지 토양 미생물의 다양성을 지도화 하였다. 1999년부터 2007년까지 조사되어 농업환경변동조사로 구축된 미생물 균수 및 미생물체량 자료를 DB화하여 세균, 사상균, 바실러스, 그람음성균 및 미생물체량을 분포도 작성에 이용하였다. 세균, 사상균, 바실러스 및 그람음성균의 분포상은 농경지별로 상이한 경향을 보였다. 토양에 서식하는 미생물의 생체중인 미생물체량은 바실러스와 사상균 수처럼 증가하는 경향을 보였다.
