The invention discloses a method for automatically extracting the tree height of a standing forest having high canopy density based on TLS and UAV. By utilization of UAV photographic measurement pointcloud data and ground precise point cloud data, the highest point and the lowest point of an individual tree are extracted; according to an individual tree positioning coordinate and automatic identification highest point information, the judged highest point and a positioning point are projected in a xoy plane; the identification accuracy is judged; and thus, a tree height value is rapidly extracted. The cost is reduced; the efficiency is increased; furthermore, on the premise that the tree height extraction precision is increased, partial manual survey is replaced; a lot of manpower and material resource consumption can be reduced; a test result shows that: the tree height extraction method provided by the invention has relatively high precision for tree height estimation of an artificial metasequoia forest; the tree height extraction value whole is closer to the actual measured value; and furthermore, the method in the invention also makes effective recommendations for forest resource assessment and business planning of small and medium-sized farms.

The invention belongs to the technical field of plant cultivation, and relates to an industrialized water culture method for metasequoia cuttings. The method comprises the steps of 1, selection and treatment of the cuttings; 2, preparation of a nutrient solution; 3, construction of an industrialized plant water culture system; 4, seedling management. Specifically, the method comprises the steps that the cuttings each of which is about 10 cm long and contains 2-3 buds are cut from metasequoia seed trees which grow well for 2-10 years; one-third parts of the cuttings are soaked in a 10 g / L rooting powder solution for 24 h and then placed in clear water for soaking for two weeks, and the cuttings root under dark conditions; two weeks later, the cuttings are fixed by planting cotton and planting baskets and placed on a perforated foam plate, the foam plate is placed on a water culture box with the nutrient solution, it is ensured that the one-third parts of the cuttings are fully soaked in the nutrient solution, appropriate illumination is supplied, and the growth temperature of metasequoia and the oxygen supplying time of the water culture are controlled; the nutrient solution is changed every week, and the growth condition of the cuttings is monitored in real time; after two months, the survival rate and rooting quantity of metasequoia are measured. It is discovered from results that metasequoia after the water culture by means of the method grows well, the survival rate and the rooting rate are both relatively high, the survival rate after the metasequoia cuttings are transplanted is high, and the trees are beautiful in shape.
