Since 1952, afforestation has started, and the use of banned feet inside and outside the embankment has been planned to create a wave-sheltered forest and a timber forest. At present, the embankments of other embankments can not be afforestated but the other embankments have been afforestated. Pro-surface has 1.77 million anti-wave forest, back 1.29 million useful timber forest, embankment inside and outside the total of 3.06 million trees, an average of 6,709 trees per kilometer. The general embankment has trees 5-10 lines, up to 20-30 lines, 5 meters above the tree, the forest is now a line, lush, become a dry barrier along the banks of the Hanjiang River green barrier. First, the effectiveness of anti-bounded forest
