The evaluation result is that the ecological security index of Qinhuangdao is 0.633, and it is in the lower bound of the relatively safer state. At present, the main ecological problems are water shortage, water pollutions, large quantity of gaseous pollutants emission from heavy industry enterprises, inadequate protection of natural reserves, and insufficient investments in environmental protection.
Some targeted countermeasures for strengthening regional ecological security management are proposed as following: establishing ecological security early warning system, developing and utilizing water resources rationally to improve water utilization efficiency, strengthening the marine environmental protection to ensure the security of marine environment, reducing sulfur dioxide emission volume by improving air quality through an effective way, and implementing ecological restoration project to improve the ecological carrying capacity. The ecology of Qinhuangdao would move to a safer ecological level through these channels.
