基于航空点云的落叶松林分蓄积量建模和应用测试初探

Based on the LIDAR point cloud and ground sample survey results obtained from the satellite-air-ground comprehensive test in the Northeast China Tiger and Leopard National Park,with emphasis on the larch(Larix spp.)case,this paper explored the laser radar survey mode method of larch forest volume model theory,and combined with the type 2 investigation results of key state-owned forest region of Inner Mongolia in northeast China.The results of the model were used to preliminarily calculate the hectare stock of some type 2 subcompartments of larch in this area,which was an effective attempt to apply the results of the Lidar research model in the direction of business application.From the model results and application test results in a small scale,larch forest stand volume precision of the model could meet the requirements of the forest resource planning and survey technology regulation,thus it can be applied in practice.To achieve truly scale business production and application,we need to make deep efforts in model precision,universality and scale application efficiency.
