摘要: 生物液体燃料是一种重要的可再生能源,其优势在于能够缓解能源危机并减少温室气体排放。因此,能源作物的规模化种植受到各国政府的广泛关注。亚洲占据了世界上最多的人口,同时,经济发展非常迅速,粮食安全与能源危机两大问题并存。本数据集提出了利用宜能边际土地资源种植非粮能源作物的思路,在亚洲尺度上,对宜能边际土地资源的空间分布进行研究。本数据的研发采用多因素综合评价方法得出,即综合考虑自然条件、土地利用格局等因素,因此研究所需的数据包括基础地理数据和自然背景数据。其中基础地理数据又包括了土地利用数据和DEM数据;自然背景数据包括气象数据和土壤数据。根据文献资料及专家经验,设定典型能源植物对温度、水分、坡度和土壤等条件的限制阈值,综合考虑能源作物生长所需适宜性条件并结合以上数据,获得亚洲宜能边际土地资源分布数据集。数据结果表明,亚洲宜能边际土地资源总面积为1699.55万 km2。数据检验以中国能源植物种植示范基地华南植物园和武汉植物园为地面验证数据,精度均高于85%,说明了亚洲宜能边际土地资源数据集的可靠性,中国以外区域暂未进行验证。该数据集为亚洲能源植物规模化种植及生物能源可持续发展提供了数据支持。

Abstract: The launching of rocket and satellite was one of the major tasks of International Geophysical Year (IGY). The first of Russia satellite named Sputnik 1 was successful launched on 4 October 1957, which is recognized as a milestone for a new era - a space age. Besides the satellites of Sputnik 1, 2 and 3, Luna 1, 2 and 3 from Russia, the Explorer 1, 3, 4, 6, 7, Vanguard 1, 2, 3, Pioneer 1,2,3, 4, Discoverer 1, 2, 5, 6, 7, 8 and Score from USA were successful launched from 1957-1959 in IGY (The Rocket and Satellite task was extended for implementation for one more year in 1959 than that of tasks else from 1957-1958). For celebrating and commemorating the great achievements in human history, 23 countries in the world issued post stamps during IGY, the first three years of the space era. The collection of post stamps consisted of 349 pieces from 23 countries are archived in LIN Chao Geomuseum (www.geomuseum.cn), The dataset consisted of 349 .jpg files for all of archived stamps and one table file which is the list of the collections. The code, image, date issued, country issued, contributor and descriptions are listed at the table items.
