Abstract:

The research about eco-security is the forward question of the sustainable development. The eco-security of wetland means that the wetland ecosystem should be of integral and normal structure and function, and can provide sustainable and stable services or resources which are necessary to human being. This study is to establish the index system of wetland eco-security by the principle of integral, sensitive ,eco-fragile scientific and manipulatable. Binding the conception model of “pressure-state-response" and the realistic environmental problrem which Zhalong wetland is facing, we evaluated the eco-security condition of Zhalong wetland. The comprehensive evaluation result shows that: the eco-security of zhalong wetland is about 4.717, It is alert. The eco-security of the whole wetland inclines to high alert to be worse, the protection should be strengthened.

Key words: Zhalong wetland, eco-security, index system
