The material circulation and energy flow in the wetland is fast and efficient, which has an important value to maintain the biodiversity and productivity.
The normal succession process of microbial community was affected, oil ecological system being vulnerable, material circulation was blocked and the microorganism resource gradually reducing.

The Young’s modulus of material E = 206GPa, Poisson’s ration ν = 0.3, density ρ = 7,850 kg/m3, and the yield strength of steel fy = 235MPa are adopted in this example.
The remaining material volume of the optimal bracing layout is only 7.9% of the initial design domain, and its maximum inter-story drift and the fundamental natural period are 0.013m and 1.23s respectively.
