采伐后迹地留下大量采伐剩余物,如枝桠、梢头木等。据调查资料:伐区各种剩余物占采伐量的38—40％,其中枝桠和梢头占15％,伐根占10％,造材剩余物占3—5％,树皮占10％。全国可利用的采伐剩余物每年达一千万立方米。按此推算,我区约有近十万立方米的采伐剩余物。 Logs left after logging a large number of logging residues, such as branches, shovel wood. According to the survey data, all kinds of residues in the cutting area accounted for 38-40% of the total cutting volume, among which, 15% were branches and shovels, 10% were spiked roots, 3-5% were used for residue from construction materials and 10% were barks. The available logging surplus in the country amounts to 10 million cubic meters a year. According to this projection, my area has about 100,000 cubic meters of logging leftovers.
