Introduction to Liangshui Nature Reserve: Liangshui National Nature Reserve is located in the northern center of Dailing District, with Hongguang, Hanyue, Beili and Mingyuesi of Dailing Forestry Experimental Bureau on the east, north and west respectively. The two poplar forests are adjacent to each other, and the south is adjacent to the Bishui Experimental Forest Farm. The protected area covers an area of 12,133 hectares. The main protection object is the temperate coniferous and broad-leaved mixed forest ecosystem dominated by Korean pine. This is the most typical and complete broad-leaved Korean pine forest ecosystem currently preserved in my country, and it is of extremely far-reaching significance.
