Abstract: |
Baiyangdian Lake is the "Pearl of North China" and an important ecological support for Xiong' an New Area. The vulnerability assessment of water environmental risk targets can provide a basis for the water environmental protection and the risk management of water pollution accidents in Baiyangdian Lake. In terms of the sensitivity and buffering ability of risk targets, 14 indicators were selected to build an indicator system to evaluate the vulnerability of water environmental risk targets, and a method of vulnerability assessment and classification was proposed to evaluate the vulnerability of the risk target. The results showed that Baiyangdian Lake overall exhibited lower and low vulnerability, while the northeast, northwest, and middle parts of Baiyangdian Lake exhibited higher vulnerability. Measures should be taken to improve the buffering capacity and reduce the vulnerability by controlling pollution, strengthening ecological water compensation, planting aquatic vegetation, and reconstructing micro-slope. |
