Abstract

In the Jinshajiang Watershed, degraded forestland, which included intensively-cut forests, early-restored secondary natural forestland, sparse forestland, brush land, and bare land, was analyzed after disturbance. Disturbance factors were divided into four grades of artificial interference and then ranked. Results of the four grades of disturbance showed:(a) 24 types of degraded forest stands were almost intact forests,(b) 14 types had slight-disturbance,(c) 14 types revealed mid-disturbance, and (d) 19 types showed intensive-disturbance. This grouping will help to better carry out protection of the Jinshajiang Watershed and ecosystem environmental management.
