Combining the ecological characteristics of organisms with the climate map, it becomes a bioclimatic map. For example, the optimum temperature and humidity range of Cercospora, which harms citrus, is between 16 ~ 32℃ and 75 ~ 85%. The inner, middle and outer rectangles in the figure represent their optimal, suitable and tolerable ranges respectively. The bioclimatic map shows intuitively that the temperature and humidity in Honolulu, Lu Lu badminton are suitable for the growth and development of grouper all year round. Climate map is a useful tool to analyze the distribution and potential distribution areas of organisms and predict the results of introduction and domestication. Because temperature and salinity are two important limiting factors in the ocean, marine ecology often draws hydrogeologic maps of temperature and salinity according to their monthly changes. Because there are many climatic factors that affect the growth, development or activities of organisms, polygonal climate maps can also represent the complex climatic characteristics of biological habitats.
