The invention relates to a thermal power plant coal inventory measuring and calculating method based on a four-axis aircraft. The method includes the following steps that (1) laser distance measurement is conducted over a coal pile, the straight-line distance h between an acquisition point over the coal pile and a surface point of the coal pile is measured, the straight-line distance between the acquisition point and the horizontal plane of a place where the coal pile is located is H, the straight-line distance z between the surface point of the coal pile and the horizontal plane of the place where the coal pile is located is equal to H-h, and meanwhile, horizontal coordinates x and y of the acquisition point are acquired through a GPS positioning module; (2) the step (1) is repeated, so that the straight-line distances between multiple acquisition points over the coal pile and multiple surface points of the coal pile and horizontal coordinates are acquired, the straight-line distances between the surface points of the coal pile and the horizontal plane of the place where the coal pile is located are acquired through the straight-line distances between the acquisition points over the coal pile and the surface points of the coal pile, and therefore a coal pile vertical view outline is drawn; (3) the approximate size of the coal pile is calculated through the straight-line distances between the surface points of the coal pile and the horizontal plane of the place where the coal pile is located and the horizontal coordinates of the acquisition points. The method is suitable for measurement conducted in various environments and large-area region measurement can be achieved.

The invention relates to the fields of genetic engineering and microbial fermentation, and discloses a recombinant strain producing terpenoids, a construction method thereof, and a method and application for fermenting terpenoids. The recombinant strain is obtained by genetic engineering of the starting strain, and compared with the starting strain, the activity of α-humulene synthase and the flux of mevalonate pathway and acetyl-CoA are respectively enhanced in multiple organelles of the recombinant strain, Or enhance the activity of squalene synthase and the flux of mevalonate pathway and acetyl-CoA, respectively; wherein, the multiple organelles of the recombinant strain include the cytoplasm and peroxisome, and the cytoplasm and peroxisome are respectively Contains a gene encoding α-humulene synthase, or a gene encoding squalene synthase, respectively. The recombinant strain provided by the invention can effectively increase the output of α-humulene or squalene, and has the advantages of raw material regeneration, mild conditions, green production, and is not restricted by time and place.
