大力开发非耕地资源,农、林、牧、渔综合发展,全方位开发食物来源是保障我国未来16亿人口食物安全的重要途径.我国山区占国土面积近70%,人口占全国56%,拥有全国森林面积的90%,是木本粮油、野生植物淀粉、竹、果、藤、香料,药材等产品的主要生产基地,是我国重要的非耕地资源.新中国成立以来,科学技术的进步促进了经济林和竹、藤业的蓬勃发展,为国家建设和人们生活提供了丰富的森林食物和工业原料,成为发展山区经济,促进农村脱贫致富和劳动就业的支柱产业,同时还发挥着保护和改善生态环境的巨大功效.在2L世纪里,经济林和竹、藤业有着更大的社会需求,将在中国人靠自己养活自己,生活得更美好的奋斗中继续发挥着不可替代的、越来越大的作用.据预测在未来30年间对木本粮油、竹和藤产品的需求将有成倍的增长,到2010年需求栗、枣、柿三大骨干木本粮食产品350~380万T,油茶、核桃等木本食用油75~85万T,竹材2400~2500万T,竹笋300~320万T,棕榈藤5~6万吨.到2030年需求木本粮食品1060~1200万T,木本食用油170~180万T,竹材4000~4500万T,竹笋600~700万T.“,”It is one of the important ways for food security of the future for 1. 6 billions people in China by overall exploiting of foods in agriculture, forestry, animal husbandry, and fishery. In the country, seventy percent of land out of total territory is mountainous areas, in which around 70 percent of the total population live and ninety percent of forest resources grow. And also the mountainous areas are the production bases for woody foods, oils, wild plant starch, bamboo, rattan, fruits, natural perfumery, and herbal medicines as well.Since the foundation of the new China in 1949, the progress of Sci-tech has being promoted the development of cash forest plantations, bamboo and rattan industry, which have provided numerous forest foods and industrial materials and also generated huge income for the poor and provided a lot of employment opportunities. Meanwhile, it also functions very well in ecological protection.In the coming 21st century, there will be a bigger demand on the products of the cash forest plantations, bamboo and rattan industry. They will hold an unreplacable, possibly bigger than ever before, role in feeding Chinese by themselves. It has been predicted that the demand on the products of cash plantations, bamboo and rattan industry will be doubled in the future 30 years. Till 2010, the demand on three major woody foods such as nut, jujube and persimmon will reach 3. 5~3. 8 million tones; the demand on woody oil products such as tea oil and walnut will reach 0. 75~0. 85 million tones; the demand on bamboo timber and edible bamboo shoots will reach 24~25 million tones and 3. 0~3. 2 million tones respectively; and demand on rattan products will reach 50~60 thousands tones as well. It also has been predicted that the demands on woody foods, woody edible oil, bamboo timber and edible bamboo shoots will reach 10. 6~12. 0 million tones, 1. 7 ~1. 8 million tones, 40~45 million tones and 6~7 million respectively around 2030.
