The present invention relates to the field of wildlife protection, and particularly relates to a method for observing wildlife population size through a remote sensing imagery. The method specifically comprises: a proportion of orthogonal projection area of animals in each pixel to pixel area is computed and summed through a linear correlation between a gray value of a remote sensing imagery pixel and a proportion of the orthogonal projection area of individual animals to the pixel area, to obtain the total orthogonal projection area of target animal population; and population size is obtained on the basis of dividing by the orthogonal projection area of animals of measured individual animals, thereby solving the problem that it is difficult to observe the wildlife population size and a distribution pattern at the same time point. In the present invention, a satellite remote sensing imagery is used to observe the animal population to obtain the population size at the same time point, thereby avoiding errors caused by the pasting counting, estimation and other methods and increasing investigation accuracy and reliability. In the present invention, the remote sensing imagery is used to observe the animal population, thereby avoiding disturbance to animal behaviors and destruction to habitats of the wildlife due to short-distance observation of the wildlife, greatly enhancing safety and economy of field observation and realizing higher application value.
