In addition to such ecological problems as the pollution of the water system, the unreasonable structure of the upstream Basin and the insufficient water conservation forests, the Xizhi River Basin also faces human decision-making problems such as imperfect ecological compensation mechanism. In view of the above problems, using the DPSIR model (Drivers, Pressures, States, Impacts, Responses), this paper analyzed eucalyptus forest in Xizhi River Basin to assess the security of the Xizhi River ecological Basin, and finally concluded that the ecological status of Xizhi River Basin remains safe.
