Muli County is located in the west of Liangshan Prefecture, at the junction of Qinghai-Tibet Plateau and Yunnan-Guizhou Plateau. Terrain is remnant tableland, ravines are vertical and horizontal, and erosion is deep. It is one of the areas with the most complicated geological structure and the worst environment in Qinghai-Tibet Plateau. The location of the fire site is high above sea level, the wind speed is fast and uncertain, the terrain is very steep, and there are no formed roads in many places, which brings difficulties to the fire fighting work.

The existing forestry land area in Muli County is 9410.4 million hectares, including 620,000 hectares of woodland, with a forest coverage rate of 67.3%, and the standing stock1.10.7 billion cubic meters, accounting for 10% of the whole province and10% of the whole country. This is one of the few remaining primitive forest areas in Chinese mainland. Therefore, Muli County has the reputation of "a tree and a half forest".

Muli forest region belongs to the subtropical monsoon climate zone in the northern hemisphere, with distinct dry and wet seasons, with an average annual precipitation of 865,438+08 mm.

Every June 1 1 to the following June, the precipitation is less than 10% of the whole year, the air is dry, and there are many windy days. In addition, the wind direction in the forest area changes with the abnormal terrain, there are many kinds of flammable conifers in the forest area, and the humus layer under the forest is thick, so people enter the forest area frequently. Therefore, the forest area has a high fire risk grade and great fire hidden danger, and is listed as a national first-class key fire risk area.
