我国现有经济林面积1.69亿亩,占森林总面积的10.2％。经济林产品收入是林业收入的重要组成部分,按现行收购价格计算,1987年我国主要经济林产品产值约41亿元,占全国林业总产值的1/4左右。1986年我国经济林产品出口量为52万吨,创汇3.1亿美元,占林产品出口创汇总额的53％以上。一些经济林产品已成为我国人民食品结构的主要成分,如油茶的主产在湖南、江西二省,人均食油50％以上来自茶油。在许多集中产区,经济林产品收入占当地农业总收入的30％左右,高的达70％以上。因此,加速经济林生产的发展具有重要的现实意义。
China’s existing economic forest area of 169000000 acres, accounting for 10.2% of the total forest area. The income of economic forest products is an important part of forestry income. According to the current purchase price, the output value of major economic forest products in 1987 was about 4.1 billion yuan, accounting for about 1/4 of the total output value of forestry in China. In 1986, the export of economic forest products in China was 520,000 tons, earning 310 million U.S. dollars, accounting for more than 53% of the total foreign exchange earned by forest products export. Some economic forest products have become the main components of the people’s food structure in our country. For example, the main products of Camellia oleifera are mainly from tea oil in Hunan and Jiangxi provinces, with more than 50% of the average per capita consumption of cooking oil. In many areas with concentrated production, the income from economic forest products accounts for about 30% of the total agricultural income in the local area and a high of more than 70%. Therefore, accelerating the development of economic forest production has important practical significance.
