苏门答腊岛-世界地理数据大百科辞条

基于Googth Earth的遥感影像得到的苏门答腊岛海岸线数据表明，全岛总面积428479.63平方千米，全岛海岸线长15320.39千米。苏门答腊岛西部的海岸线较为平缓，东部的海岸线较为曲折。苏门答腊岛是世界第六大岛屿，位于南纬5度56分34.83秒-北纬5度39分24.67秒；东经95度11分37.64秒-106度5分47.22秒之间。全岛最大长度为1720千米，最大宽度为408千米。苏门答腊岛北接安达曼群岛，在东南部隔巽他海峡与爪哇岛相望，在东北部隔马六甲海峡与马来半岛毗邻，在岛的东部区域则与邦加岛和勿里洞岛隔海遥接。位于岛的西部地区巴里散(Barisan)山脉呈西北-东南走向，山脉绵延近1700千米，海拔最高点超过3800米。在岛的东部地区为广阔的冲积平原，复杂的水系在这里纵横额交错。赤道穿越了苏门答腊岛，这里是典型的热带雨林气候。岛上的年平均气温没有太大的差别，但是降雨的分布却不尽相同。苏门答腊岛西海岸年降水量约为3000毫米，而山区可达4500-6000毫米；山脉以东区域降水量约为2000-3000毫米，岛的南北两端年降水量约为1500-1700毫米。苏门答腊岛是印度尼西亚的最大的岛屿，包括10个省份，它们分别为：亚齐省，邦加－勿里洞省，明古鲁省，占碑省，楠榜省，廖内省，廖内群岛省，西苏门答腊省，南苏门答腊省，北苏门答腊省。

Coastal line data of the island of Sumatra derived from remote sensing imagery obtained via Google Earth indicates that the total area of the entire island is 428,479.63 square kilometers, and the total length of its coastline is 15,320.39 kilometers. The western coastline of Sumatra is relatively gentle, while the eastern coastline is more tortuous. Sumatra is the sixth largest island in the world, located between 5°56'34.83"S to 5°39'24.67"N latitude and 95°11'37.64"E to 106°5'47.22"E longitude. The maximum length of the entire island is 1,720 kilometers, and the maximum width is 408 kilometers. Sumatra borders the Andaman Islands to the north, faces Java Island across the Sunda Strait in the southeast, adjoins the Malay Peninsula across the Malacca Strait in the northeast, and is separated by sea from Bangka Island and Belitung Island in its eastern region. The Barisan Mountains in the western part of the island run in a northwest-southeast direction, stretching for nearly 1,700 kilometers, with the highest elevation exceeding 3,800 meters. The eastern part of the island is a vast alluvial plain, where complex drainage systems crisscross. The equator passes through Sumatra, which has a typical tropical rainforest climate. The annual average temperature on the island does not vary significantly, but the distribution of rainfall is different. The annual precipitation on the western coast of Sumatra is approximately 3,000 millimeters, while that in the mountainous areas can reach 4,500-6,000 millimeters; the area east of the mountains has an annual precipitation of about 2,000-3,000 millimeters, and the annual precipitation at the northern and southern ends of the island is approximately 1,500-1,700 millimeters. Sumatra is the largest island in Indonesia, consisting of 10 provinces, namely Aceh, Bangka-Belitung Islands, Bengkulu, Jambi, Lampung, Riau, Riau Islands, West Sumatra, South Sumatra, and North Sumatra.
