To this end, the city of Beijing eight districts on both sides of the green road to fill a variety of shelves to the plant to do “warm cover.” However, the first priority of these “warm covers” is not to prevent cold, but to prevent the deicing salt from damaging the trees. According to a recent statistics from the Beijing Municipal Department of Landscaping, from the end of 2004 to the beginning of 2005, more than 10,000 trees in Chengbei District died, with more than 1.49 million hedges and patches of shrubs and nearly 200,000 square meters of lawn suffering serious salt damage Or died, the direct economic loss of more than 30 million yuan.
