斯里兰卡海岸线数据集 - 世界地理数据大百科辞条

斯里兰卡位于亚洲南部，北纬9度50分40 秒- 5度55分8秒；东经81度52分47秒-79度27分5秒。它隔保克海峡和马纳尔海湾与印度次大陆相连， 通过马纳尔岛经亚当桥（一系列沙洲和岛屿组成的沙洲岛链）与印度相接， 西南与马尔代夫隔海相望。 斯里兰卡包括斯里兰卡岛及其周边的岛屿，其中包括马纳尔岛、贾夫纳岛、代尔夫特岛、蓬库社岛、奈纳岛、阿讷莱岛、曼代岛、卡莱纳嘎尔岛等。基于Googth Earth的遥感影像得到的斯里兰卡海岸线数据表明，斯里兰卡南北长435公里， 东西宽226公里。全国总面积65,817.24平方公里，其中斯里兰卡岛面积65437.10平方公里， 其余岛屿面积380.14平方公里。全国海岸线长4,349.68公里。其中， 斯里兰卡岛海岸线长3,455.31公里，其余岛屿岸线长894.37公里。 斯里兰卡岸线比较平直， 多为沙质海滩，在海陆相互作用下，沿海形成了一系列泻湖， 这些泻湖构成了岸线的曲折部分。斯里兰卡中南部为山地， 最高峰皮杜鲁塔拉格勒山海拔2524米。由该山峰向各个方向呈辐射状分布短小河流。斯里兰卡地处热带海洋性气候带， 终年高温湿润，平原和沿海地区年平均温度在27℃。斯里兰卡降水受到西南季风和东北季风的双重影响， 其中，岛屿的西、南和中部地区的降雨主要受到西南季风影响，雨季为每年五月到七月；东北和北部主要受到东北季风影响， 雨季在12月和1月，全国大部分地区年平均雨量在1300-2300mm。斯里兰卡首都是斯里贾亚瓦德纳普拉， 它位于商业首都科伦坡的南郊，该都城市建设与科伦坡连为一体。斯里兰卡全国划分9个省（行政区划）、25个行政区。9个省为：中央省，北中央省，东部省，西北省，萨巴拉加穆瓦省，南部省，乌瓦省，西部省和北部省。25个行政区为：科伦坡，康提，努瓦里埃利亚，汉班托塔，阿努拉德普拉，加勒，婆罗那拉瓦, 库鲁尼加拉，亭可马里，贾夫纳，玛塔拉，巴杜勒，卡鲁塔拉，安姆普拉， 默纳拉加勒,马特勒, 拜蒂克洛, 基利诺奇, 瓦武尼亚, 穆莱蒂武, 马纳尔, 普塔拉姆, 加姆帕哈, 开格勒和拉特纳普勒。

Sri Lanka is located in southern Asia, with latitudes ranging from 9°50′40″N to 5°55′08″N and longitudes from 81°52′47″E to 79°27′05″E. It is separated from the Indian subcontinent by the Palk Strait and the Gulf of Mannar, and connected to India via Mannar Island and Adam's Bridge, a chain of sandbanks and islets. It faces the Maldives across the sea to the southwest.

Sri Lanka encompasses the main island of Sri Lanka and its surrounding outlying islands, including Mannar Island, Jaffna Island, Delft Island, Punkudutivu Island, Nainativu Island, Analaitivu Island, Mandaitivu Island, Kakarathivu Island, and others.

Coastline data of Sri Lanka derived from remote sensing imagery via Google Earth shows that the country extends 435 km from north to south and 226 km from east to west. The total national area is 65,817.24 km², of which the main island covers 65,437.10 km², and the remaining outlying islands have a total area of 380.14 km². The total national coastline is 4,349.68 km long, with 3,455.31 km on the main island and 894.37 km on the outlying islands.

The coastline of Sri Lanka is relatively straight, mostly composed of sandy beaches. Under the interaction of land and sea, a series of lagoons have formed along the coast, which form the tortuous sections of the shoreline.

The central and southern parts of Sri Lanka are mountainous, with the highest peak, Pidurutalagala, standing at an elevation of 2,524 m. Short rivers radiate outward from this peak in all directions.

Sri Lanka has a tropical marine climate, with high temperatures and humidity throughout the year. The annual average temperature in the plains and coastal areas is 27°C. Precipitation is influenced by both the southwest monsoon and the northeast monsoon. The western, southern and central regions of the island are mainly affected by the southwest monsoon, with the rainy season falling from May to July each year; the northeastern and northern regions are mainly affected by the northeast monsoon, with the rainy season occurring in December and January. The annual average rainfall in most parts of the country ranges from 1,300 to 2,300 mm.

The capital of Sri Lanka is Sri Jayawardenepura Kotte, which is located in the southern suburbs of the commercial capital Colombo, and the urban construction of the capital is integrated with that of Colombo.

Sri Lanka is divided into 9 administrative provinces and 25 districts. The 9 provinces are: Central Province, North Central Province, Eastern Province, North Western Province, Sabaragamuwa Province, Southern Province, Uva Province, Western Province, and Northern Province. The 25 districts are: Colombo, Kandy, Nuwara Eliya, Hambantota, Anuradhapura, Galle, Polonnaruwa, Kurunegala, Trincomalee, Jaffna, Matara, Badulla, Kalutara, Ampara, Monaragala, Matale, Batticaloa, Kilinochchi, Vavuniya, Mullaitivu, Mannar, Puttalam, Gampaha, Kegalle, and Ratnapura.
