Different from traditional democracy, ecological democracy not only concerns the interests of people, but also pays attention to the benefits of nature. Its goal is the harmony, freedom, equality and sustainable development between humans, nature and society as a whole. Ecological democracy based on ecological information is necessary with dialogue, communication, exchange and consultation in order to jointly govern and protect the environment because the administrative region has divided the integrity and coherence of the geographical conditions into fragements. The scientific ecological information system constructed in relation to each other can predict the overall ecological evolutional trend and formulate corresponding counter measures. Ecological information plays an important and basic role to achieve the reconciliation between people and nature, and people to people.
