Chinese geography survey classification: Geography
Geographical position
China located at Asia east, Pacific Ocean West bank, carries Lu Mianhai, the flood and field has both. China is vast in territory, north north of Heilongjiang Province Mohe River's Heilongjiang main channel middle line (north latitude 55o many), in the winter solstice Nansha Islands' Zengmu Reef (nearby north latitude 4O), the north and south are distanced the approximately 5500 kilometers; East has Heilongjiang and the Wusuli River main channel junction (east longitude 135o many), west to the Xinjiang Pamirs (nearby east longitude 73o), the thing is distanced the approximately 5000 kilometers.
Land area
The Chinese territory area approximately is 9,600,000 square kilometers, approximately composes the Asian land area 1/4, approximately composes the world land area 1/15, is only inferior to Russia and Canada, occupies world third.
Landform
The Chinese terrain is diverse, the type is complete, mountainous region, plateau, hill, basin, plain, Gobi, desert, cavern typical magnificent. The terrain distributed rule is west the topography Gao Dongdi, assumes the third-level steps and ladders, from west, but east, progressive drop. The Chinese plain are few, the mountainous region are many, the land elevation difference is disparate. The mountainous region, the plateau, the hill and so on approximately compose the total area 66%, the flat land approximately composes 34%. The national nearly 70% county area distribute in the mountainous area. The mountainous region and the plateau concentrate in the western area. The elevation 500 meters following areas only occupy the national area 16%; Elevation 1000 meter above reaches as high as 65%. The whole world is higher than in 8000 meters 12 mountain peaks, China has 7. Chinese and Nepalese abutment's place Mount Everest, the elevation 8848.13 meters, are the world high points. Xinjiang Turfan basin Aydingkol Lake elevation below 155 meters. The Chinese land positive and negative surpasses 9000 meters compared to the difference, is the world.
The Qinghai-Tibet Plain is west China Gao Dongdi the third-level steps and ladders topography highest stair, above the average elevation 4000 meters, many mountain high mountains, are known as " the roof of the world ". The highest stair edge is Kunlun Mountain - Qilian Mountain - Longmen Mountain - Daliang. Crosses the edge namely to fall to the elevation 1000~2000 meters intermediate stairs, by the inner Mongolian plain, the Loess Highlands, the Yunnan-Guizhou Plateau, the Sichuan basin, the Tarim basin and the Songorine Basin is composed. Crosses the intermediate stair's east reason Greater Hinggan Mountain - Mt. Taihang - Wushan - Xuefang, namely falls to the elevation 500 meter below preliminary stairs, by the northeast plain, the Huabei Plain, the Changjiang zhongxiayou and the south of Yangzi River hill, the Fujian and Guangdong hill is composed. The preliminary stair's southeast edge is the water depth is smaller than 200 meter epicontinental sea continental shelves, is the mainland extends the part to the sea nature.
Chinese terrain pattern many take sierra as base line, moves toward and the origin different sierra often is the important geography boundary. The nation may divide into three nature areas:①By fluviation eastern monsoon moist landform area primarily;②By the wind erosion, the glacial erosion and the fluviation mixes the camp the northwest arid landform area;③Freezes, the wind abrasion Qinghai-Tibet Plain high and cold landform area primarily.
Border and neighbors all about
Chinese land boundary long approximately 22,800 kilometers, Chinese on land border long more than 20,000 kilometers, east has North Korea, Northeast has Russia, north has Mongolia, the northwest has Russia, Kazakhstan, west has Kyrgyzstan, Tajikistan, Afghanistan, Pakistan, the southwest has India, Nepal, the Sikkim, Bhutan, south has Burma, Laos, Vietnam. The Chinese coastline be more than 18000 kilometers, surround the continental margin the sea are in turn: Bohai Sea, Yellow Sea, East China Sea and South China Sea. The neighboring country which faces each other across the sea with China respectively is: Japan, South Korea, Philippines, Brunei, Malaysia and Indonesia.
