大伙房林场现有长白落叶松人工林的面积占有林地总面积的36.4％,占总蓄积的42.8％。如何科学地经营好长白落叶松人工林,是我场在森林经营上举足轻重的大问题。为了全面掌握长白落叶松人工林的立地质量和生产力,合理预测产量,提高集约经营技术。试用地位指数表的方法,对长白落叶松人工林的生长进行了分类评价,目的是促进我场人工林经营技术的发展和提高。大伙房林场大部分长白落叶松人工林已经过抚育间伐,而利用上层优势木作为指标不受正常抚育间伐的影响,因此,采用立地指数表法来评定大伙房林场的立地生产力,较为准确和实用。
The existing Larix olgensis plantation in Dayoufang farm occupies 36.4% of the total area of forestland, accounting for 42.8% of the total. How to operate the plantation of Larix olgensis scientifically is a big issue that my field plays a decisive role in forest management. In order to fully grasp the site quality and productivity of Larix olgensis plantation, forecast the yield reasonably and improve the technology of intensive management. In order to promote the development and improvement of plantation management technology in our field, the paper made a classification evaluation on the growth of Larix olgensis plantation. Most of Larix olgensis plantations in Dahuofang Forest Farm have undergone tending and thinning, and the use of superior dominance wood as an index is not affected by the normal tending and thinning. Therefore, using the site index method to assess the site productivity of Dahuo Fang Forest Farm is more accurate and practical .
