This invention discloses a collaborative inversion method for multiple attributes of individual trees based on transfer learning, relating to the field of forest ecological remote sensing monitoring technology. The method acquires remote sensing images and training samples, generates a canopy height model based on LiDAR point clouds, constructs and trains a single-tree segmentation model based on the U-Net++ architecture, and fine-tunes the encoder weights of the single-tree segmentation model by transferring them to a tree height prediction model and a forest type classification model. Finally, the remote sensing images are input into the three models to obtain the single-tree canopy boundary, predicted tree height, and forest type, and the integrated output is the multi-attribute inversion result for individual trees. This method addresses the problems of complex data dependencies, non-reusable features, low inversion accuracy and efficiency, and easy error accumulation inherent in traditional independent inversion of single-tree attributes.

The present application provides a kind of fern composite planting method based on birch forest, and belongs to the technical field of agricultural planting.The present application provides a kind of fern composite planting method based on birch forest in the low-quality birch forest area in northeast forest, solves the problem of low utilization rate of existing low-quality birch forest interspace and unbalanced supply and demand of fern market, and solves the problem of fern resource cultivation and artificial large-area planting difficulty.The present application solves the problem of low-quality birch forest space utilization difficulty by different forest type selection method and different canopy density fern planting method, realizes the one-year two-season harvesting mode of spring vegetable picking and autumn fruit picking by low canopy density plot black bud currant and fern intercropping, increases the utilization efficiency and multiple cropping index of interspace in forest, and provides a new mode for forest economy development and lays a foundation for forest fern industry development.
