We analyzed the destructive status of the harmful plant. The results showed that there were twenty-five harmful plant species from 19 families and 25 genus. Of the 25 harmful plants, 20 are indigenous and 5 are nonindigenous. The damaged degree of nineteen plant species reached Ⅲ grade. The damaged area of indigenous is 560 000 m2, and that of nonindigenous plants is 140 000 m2. The proportion of the indigenous and the nonindigenous is 4∶1. According to the destructive status analysis of the harmful plant, the damaged degree and area of the indigenous are larger than nonindigenous. To the main 15 harmful plants, we described their distribution, damaged area and damaged condition one by one. We also discussed the tendency of the harmful plants in this region.
