Remote sensing comprehensive monitoring method, device, terminal and medium for natural resources Technical Field The application belongs to the field of remote sensing monitoring, relates to a natural resource remote sensing monitoring technology, and particularly relates to a natural resource remote sensing comprehensive monitoring method, device, terminal and medium. Background The natural resource monitoring refers to the process of observing, evaluating and analyzing the current status of natural resources such as cultivated land, water area, mineral products, forests, grasslands, wetlands, oceans and the like and the dynamic changes thereof. The remote sensing monitoring technology can acquire the ground surface conditions in a large range, long term and periodically, and compared with the traditional monitoring mode relying on manpower field investigation, the remote sensing monitoring technology is combined for natural resource monitoring, so that the efficient and accurate monitoring effect can be realized. The remote sensing monitoring of natural resources comprises monitoring the conditions of quantity, quality, ecological conditions and the like. Currently, natural resources are monitored in terms of quantity, quality, ecological conditions and the like, and are usually obtained through analysis, identification and acquisition through different models. For example, the trained target detection model is adopted to identify the space distribution area and the position of the natural resources so as to realize quantity monitoring, the quality condition of the natural resources is obtained through inversion or regression models, and the analysis model is adopted to input data of various animals, plants, environments and the like so as to analyze and obtain the ecological condition of the current area range. However, the above process of monitoring natural resources separates the process of acquiring the number, quality and ecological conditions, and cannot acquire the correlation between the number, quality and ecological conditions, so that it is difficult to analyze the situation of the natural resources integrally in terms of number, quality and ecological conditions, for example, the number, quality change of a certain type of natural resources can cause the number, quality and ecological conditions in the whole area of other types of natural resources to change, and the above natural resource monitoring process is difficult to accurately acquire the correlation between the transformations, so that the effect of natural resource monitoring is poor. Meanwhile, when the quality condition of natural resources is acquired through a regression model pair, the regression model generally needs to be trained through a large number of samples to improve the accuracy. However, in actual production, the number of samples may be small, resulting in lower accuracy of the regression model and lower accuracy of the quality of the natural resources obtained. Disclosure of Invention The application aims to provide a remote sensing comprehensive monitoring method, device, terminal and medium for natural resources, which are used for solving the problems that the acquisition modes of quantity, quality and ecological conditions in the prior art are mutually independent, and the correlation between the quantity, quality and ecological conditions cannot be acquired, so that the effect of natural resource monitoring is poor.
