落叶松是我国主要速生树种之一。它栽植容易、适应能力强,成活率高、生长快、成材早,材质好,工艺价值高,是枕木、矿柱、电杆、桥梁以及造船和地下建筑用材的上乘材料;同时又是农村建房适宜的椽檩材,历来受到广大农民的普遍欢迎。据“五·五”清查资料,我国东北内蒙古林区现有落叶松林面积946万公顷,蓄积9.1亿立方米,分别约占该区森林总面积和总蓄积的30%与31%。其中,人工林面积已达92万公顷,并且,作为主要造林树种之一,现正以年13.7万公顷的速度在扩大。因此,分析比较营造落叶松人工林的投入产出,对于合理培育和利用落叶松人工林具有十分重大的经济意义。我国长期以来视营林为事业,培育林木不实行经济核算,因此缺乏投入产出分析的基础。本文是将林木培育拟作商品生产,按照商品经济法则,以黑龙江省带岭林业实验局的实际调查资料,结合面上情况进行测算与分析。其方法与结果供有关部门参考。
Larch is one of the main fast-growing tree species in our country. It is easy planting, strong adaptability, high survival rate, fast growth, early harvest, good material, high technological value, is a superior material for sleepers, pillars, poles, bridges and shipbuilding and underground construction materials; Housing suitable rafter Ti material, has always been widely welcomed by the majority of farmers. According to the “May, 5th” inventory data, the existing larch forest area in northeastern Inner Mongolia was 9.46 million hectares, occupying 910 million cubic meters, accounting for about 30% and 31% of the total forest area and the total area of the area respectively. Among them, the plantation area has reached 920,000 hectares, and as one of the major afforestation species, it is expanding at a rate of 137,000 hectares a year. Therefore, it is of great economic significance to analyze and compare the input-output of larch plantation to reasonably cultivate and utilize larch plantation. For a long time, as a cause of our work, we have not carried out economic accounting in forest cultivation. Therefore, we lack the basis of input-output analysis. In this paper, we plan to cultivate forest trees for the production of commodities, according to the laws of commodity economy, with the actual investigation data of Heilongjiang Province with the Forestry Bureau, with the situation on the surface of the calculation and analysis. The methods and results for the relevant departments for reference.
