我国的戈壁、沙漠与沙地总面积为128.2万km~2,主要分布在西北的大部、华北的北部和东北的西部,其中干旱区戈壁约56.9万km~2,沙漠约58.7万km~2,半干旱区沙地10万km~2。整个沙区南北宽约600km,东西长约4000km,于北纬35°—50°,东经75°—125°之间呈“S”形分布。干旱是这里最显著的气候特征,年降水量从西部的几十毫米到东部的300—400mm,以至500mm,且多集中于夏季。由于自然及人为因素的影响,沙漠化日趋严重,波及到新疆、内蒙、青海、宁夏、陕西、山西、河北、河南、辽宁、吉林、黑龙江等工2个省(区)的
The total area of deserts and sandy land in Gobi of our country is 1,282,000 km 2, mainly distributed in most of the northwest, northern part of North China and western part of northeast China, with a total area of 569,000 km 2 in the arid region and 587,000 km ~ 2, sandy land in semi-arid area 100,000 km ~ 2. The entire sandy area is about 600km wide from east to west with a width of 600 km and an “S” shaped distribution between 35 ° -50 ° north latitude and 75 ° -125 ° east longitude. Drought is the most prominent climatic feature here, with annual precipitation ranging from tens of millimeters in the west to 300-400 mm in the east, and up to 500 mm, with an increased concentration in summer. As a result of natural and man-made factors, the desertification has become increasingly serious and has spread to two provinces (autonomous regions) in Xinjiang, Inner Mongolia, Qinghai, Ningxia, Shaanxi, Shanxi, Hebei, Henan, Liaoning, Jilin and Heilongjiang
