一、聚焦我国西南地区自然灾害【背景材料】我国西南地区位于华北、华中、华南和青藏高原地区之间,西南部毗邻缅甸,该区域地理环境最显著的特点就是地形复杂多样。在这样的地理环境条件下,该地区自然灾害的种类也是非常多的。2011年年初的大旱刚刚过去,6月中旬又出现强降雨天气过程,并随之出现洪涝、滑坡、泥石流等自然灾害。7月份之后,该地降水偏少,又导致部分地区出现轻度至中度的旱情。
I. Focusing on Natural Disasters in Southwest China Background: Southwest China is located between North China, Central China, South China and the Qinghai-Tibet Plateau. The southwest is adjacent to Myanmar. The most prominent feature of the region's geography is that the terrain is complex and diverse. In such a geographical environment, there are also many natural disasters in the area. The severe drought in early 2011 just passed, and in mid-June there was a heavy rainfall and natural disasters such as floods, landslides and mudslides. After July, the rainfall in the area was on the low side, resulting in mild to moderate drought in some areas.
