亚洲热带湿润、半湿润生态地理区区域界线数据
收藏资源简介:
亚洲热带湿润、半湿润生态地理区是亚洲热带雨林、季雨林集中分布地区,是世界岛屿最密布的地区。在中尺度地球观测系统数据支持下,作者采用同级不同指标法确定该生态地理区的地理界线。划分指标包括最冷月平均气温摄氏16度、地形坡度大于7度、年降雨量400毫米等降水线、草地与灌丛界限、印度-马来植物区系分布范围等指标。区划采取主导因子与综合因子相结合的划分方法论。区域划分结果确定的亚洲热带湿润、半湿润生态地理区的范围包括:东起中国台湾省岛南部,广东雷州半岛及其以南地区、广西和云南南部最冷月平均气温在摄氏16度一线,向西与世界屋脊生态地理区南部接壤,再向西经印度、巴基斯坦,与年降雨量400毫米等降水线和灌丛草地分布相吻合,在卡拉奇以东与海岸线相接。在此线的南部的岛屿包括:西起马尔代夫群岛、英属印度洋群岛、斯里兰卡及其周边岛屿、中南半岛近海岛屿、向东至印度尼西亚巴厘岛,转向北,沿印度尼西亚加里曼岛东海岸向北,经萨兰加尼岛、菲律宾群岛至台湾岛。全区包括的疆域国家: 中国、印度、巴基斯坦、斯里兰卡、缅甸、老挝、越南、泰国、柬埔塞、马来西亚、新加坡、文莱和菲律宾、印度尼西亚等。海岸带和岛屿界线选择了与Google Earth影像匹配,数据以.shp和.kmz二种格式存储。
The Asian tropical humid and semi-humid eco-geographical region is a concentrated distribution area of Asia’s tropical rainforests and monsoon forests, and it is the world’s most densely island-studded region. Supported by mesoscale Earth observation system data, the authors adopted the method of using heterogeneous indicators at the same level to define the geographical boundary of this eco-geographical region. The division indicators include: the average temperature of 16°C in the coldest month, topographic slope greater than 7°, the 400 mm annual precipitation isohyet, the boundary between grassland and shrubbery, and the distribution range of the Indo-Malayan flora, among others. The regionalization adopted a methodology combining dominant and comprehensive factors. The scope of the Asian tropical humid and semi-humid eco-geographical region determined by the regionalization results is as follows: starting from the southern part of Taiwan Province, China, the Leizhou Peninsula of Guangdong and its southern regions, and the 16°C coldest month average temperature line in southern Guangxi and Yunnan; it borders the southern part of the "Roof of the World" eco-geographical region to the west, then extends westward through India and Pakistan, coincides with the 400 mm annual precipitation isohyet and the distribution of shrubbery and grassland, and connects to the coastline east of Karachi. The islands located south of this boundary include: starting from the Maldives Islands, British Indian Ocean Archipelago, Sri Lanka and its surrounding islands, and offshore islands of the Indochina Peninsula in the west; extending eastward to Bali Island, Indonesia, then turning north, going north along the eastern coast of Kalimantan Island, Indonesia, passing through Sarangani Islands and the Philippine Archipelago to Taiwan Island. The countries and territories included in the entire region are: China, India, Pakistan, Sri Lanka, Myanmar, Laos, Vietnam, Thailand, Cambodia, Malaysia, Singapore, Brunei, the Philippines, Indonesia, etc. The coastal and island boundaries were matched with Google Earth imagery, and the data is stored in two formats: .shp and .kmz.
