生物种群的空间分布型,是生物在特定空间中存在特征的数学描述。它反映了种群个体的散布状况以及对生境的适应,生境对生物影响的生态学关系。近几年来,国内关于昆虫、植物病原等生物种群的空间分布描述较多,但昆虫病原微生物的研究却较为罕见。研究昆虫病原微生物的空间分布型,不仅有助于病原微生物生态学的理论探讨,而且对于掌握病原微生物的流行规律,进而提高预测预报质量,制定相应的生物防治措施,均具有十分重要的经济价值。
The spatial distribution of biological populations is a mathematical description of the biological presence in a particular space. It reflects the dispersal status of individual individuals and their adaptation to habitats and the ecological relationship of habitats to biological effects. In recent years, the spatial distribution of biological species such as insects and plant pathogens in China has been described more, but the study of insect pathogenic microorganisms is relatively rare. Studying the spatial distribution of insect pathogenic microorganisms is not only helpful for the theoretical study of pathogenic microorganisms, but also has important economic value for mastering the epidemic law of pathogenic microorganisms, improving the quality of forecasting and forecasting, and developing corresponding biological control measures .
