珠穆朗玛峰北坡位于我国西藏自治区境内。该地区地形地貌极其复杂,在不到一百公里的直线距离内,海拔上升达2,060—3,000米,由于海拔骤然升高,气候变化剧烈,大致可分为亚热带区、亚热带向温带干旱过渡区和温带干旱区三个气候区域。这三个带区的森林分布状况、树种组成和林木特征等都有很大差别。现将我们的调查研究结果简述如下。
The northern slope of Mount Everest is located in the territory of the Tibet Autonomous Region of our country. The topography of the area is extremely complex. Altitude rises to 2,060-3,000 meters within a straight line distance of less than 100 kilometers. Due to the sudden elevation of altitude, the climate change is drastic and can be broadly divided into subtropical regions, subtropical to temperate transitional zones and Temperate arid zone three climatic zones. The forest distribution, tree species composition and forest characteristics of these three zones are quite different. Now the results of our survey are summarized below.
