爪哇岛—世界地理数据大百科辞条

爪哇岛位于印度尼西亚，南临印度洋，北面爪哇海，西北侧是苏门答腊岛，东面是巴里岛。基于2015年的Google Earth影像提取的数据表明，爪哇岛位于5&deg52'33.46"S - 8&deg46'49.45"S，105&deg12'34.28" - 114&deg36'20.05"E。面积为126731.47平方千米，海岸线长度为3756.59千米，是印度尼西亚境内的第5大岛，世界第13大岛。东西向最长1059.30km，南北向最宽197.17km。爪哇岛是由海底火山喷发物堆积而成的火山岛，岛上东西向分布着一系列活火山。最高峰是赛梅鲁火山（8.108&degS,112.92&degE）（3,676米）。最活跃的火山是默拉皮火山(7.542&degS 110.442&degE)。爪哇岛属于典型的热带气候，年平均气温为22℃- 29℃。一年分为两季：旱季（季风期）为每年的5—10月，雨季（非季风期）为11月—次年4月。爪哇岛典型的生态系统有北部沿海的红树林、中部的热带雨林、南部沿海的岩石悬崖带等。爪哇岛是地球上人口密集的岛屿之一。爪哇岛海岸线数据以 .kmz 和 .shp两种格式存储，压缩后数据量为502KB。

Java is located in Indonesia, bordering the Indian Ocean to the south and the Java Sea to the north, with Sumatra Island to its northwest and Bali Island to its east. Data extracted from 2015 Google Earth imagery indicates that Java spans latitudes 5°52'33.46"S to 8°46'49.45"S and longitudes 105°12'34.28"E to 114°36'20.05"E. It covers an area of 126,731.47 square kilometers, with a coastline length of 3,756.59 kilometers, making it the 5th largest island in Indonesia and the 13th largest in the world. Its maximum east-west length is 1,059.30 km, and its maximum north-south width is 197.17 km. Java is a volcanic island formed by the accumulation of submarine volcanic ejecta, with a series of active volcanoes extending along its east-west axis. Its highest peak is Mount Semeru (8.108°S, 112.92°E), with an elevation of 3,676 meters. The most active volcano is Mount Merapi (7.542°S, 110.442°E). Java features a typical tropical climate, with an annual average temperature ranging from 22°C to 29°C. The year is divided into two seasons: the dry season (monsoon period) lasts from May to October each year, while the wet season (non-monsoon period) lasts from November to April of the following year. Typical ecosystems on Java include mangrove forests along the northern coast, tropical rainforests in its central region, and rocky cliff zones along the southern coast, among others. Java is one of the most densely populated islands on Earth. The coastline data of Java is stored in two formats: .kmz and .shp, with a compressed file size of 502 KB.
