东亚季风生态地理区界线数据

东亚季风生态地理区位于亚洲东部，是以雨热同季为特点的东亚夏季风为主导因子的亚热带-温带湿润、半湿润,阔叶林-针阔混交林,人类活动悠久和活跃为主要生态地理特点的综合生态地理区域。东亚季风生态地理区界线的划分采区同级不同指标法和主导因子与综合因子相结合的划分方法。具体划分指标是：（1）南部以最冷月平均气温摄氏16度与亚洲热带湿润、半湿润生态地理区分界；（2）西南部以海拔4000m高度及坡度7度为界限与世界屋脊生态地理区分界；（3）西北部以年降水量400mm等降水线为主与干旱-半干旱区为界；（5）北部以可降水量极差值（>40mm）和针阔混交林与针叶林分界作为主导指标；（6）东部囊括千岛群岛、日本列岛、琉球群岛、台湾岛的北部等岛屿。本区包括俄罗斯、中国、蒙古的部分领土和日本、朝鲜、韩国的全部领土。地理坐标为: 13o14′34.61″N～54o25′31.79″N；98o52′27.36″E～156o30′49.37″E。地理区域北起千岛海峡，经日本至琉球群岛，至台湾北部，东起南鸟岛、小笠原群岛、硫黄列岛、向西至台湾岛北部，再向西隔海与亚洲热带湿润、半湿润生态地理区界线相连，向北与世界屋脊生态地理区界线衔接。接着，界线向西北将中国北方分割成东部季风区和西北干旱区，再至北在俄罗斯远东的哈巴罗夫斯克南部向东延伸至阿穆尔河（黑龙江）河口至鞑靼海峡。区域也包括了萨哈林岛（库页岛），在该岛经鄂霍次克海，至千岛群岛。全区面积5589938km2，海岸线长104224km。全区有岛屿13214个，分布在额霍次克海的南部、日本海、渤海、黄海、东海和台湾海峡等。数据以.shp和.kmz格式存储。

The East Asian Monsoon Eco-geographical Region is situated in eastern Asia. It is a comprehensive eco-geographical region whose dominant factor is the East Asian summer monsoon, characterized by coincident rainy and hot seasons, along with subtropical-temperate humid and semi-humid climates, broad-leaved and mixed broadleaf-conifer forests, and a long-standing and highly active human civilization history as its core eco-geographical features.
The boundary delimitation of the East Asian Monsoon Eco-geographical Region adopts the approach that combines the use of different indicators at the same classification level with both dominant and comprehensive factors. The specific delimitation indicators are as follows:
(1) The southern boundary is defined by the 16°C average temperature of the coldest month, separating it from the Asian Tropical Humid and Semi-humid Eco-geographical Region;
(2) The southwestern boundary is delimited by the 4000-meter elevation and 7° slope, separating it from the Eco-geographical Region of the Roof of the World;
(3) The northwestern boundary is mainly demarcated by the 400mm annual precipitation isohyet, separating it from the arid and semi-arid regions;
(5) The northern boundary takes the range of precipitable water (>40mm) and the boundary between mixed broadleaf-conifer forests and coniferous forests as the dominant indicators;
(6) The eastern part encompasses islands including the Kuril Islands, Japanese Archipelago, Ryukyu Islands, and the northern segment of Taiwan Island.
This region encompasses parts of the territories of Russia, China and Mongolia, as well as the entire territories of Japan, the Democratic People's Republic of Korea and the Republic of Korea. Its geographic coordinates range from 13°14′34.61″N to 54°25′31.79″N and from 98°52′27.36″E to 156°30′49.37″E.
Geographically, the region extends from the Kuril Strait in the north, passing through Japan to the Ryukyu Islands and then to northern Taiwan. In its eastern extent, it includes Minami-Tori-shima, the Ogasawara Islands and the Volcano Islands, and extends westward to northern Taiwan. Its western boundary connects across the sea with the boundary of the Asian Tropical Humid and Semi-humid Eco-geographical Region, while its northern boundary links with that of the Eco-geographical Region of the Roof of the World. Subsequently, the boundary extends northwestward, dividing northern China into the Eastern Monsoon Region and the Northwestern Arid Region. It then extends northward, stretching eastward from the southern part of Khabarovsk in the Russian Far East to the mouth of the Amur River (Heilongjiang) and onward to the Tatar Strait. The region also includes Sakhalin Island (Kuye Island), and extends across the Okhotsk Sea from this island to the Kuril Islands.
The total area of the region is 5,589,938 km², with a coastline of 104,224 km in length. There are 13,214 islands within the region, distributed in the southern Okhotsk Sea, the Sea of Japan, the Bohai Sea, the Yellow Sea, the East China Sea and the Taiwan Strait, among other areas. The dataset is stored in .shp and .kmz formats.
