Under the effects of water and salinity, the spatial distribution of the natural wetlands presented a regular change pattern.

结果表明，受水盐等因素的影响，自然湿地的分布在空间上呈现出规律性变化。

Constructing a wetlands or savanna by reassembling portions of a natural one is only one method of biome building — which the ecologists call the "analog" way.

获取自然环境中的某些部分，再将它们重新组装成湿地或者草原，只是建立生态区的办法之一，生态学家们把这种办法叫做“比对”法。

She says it is important to protect wetlands and coastal habitats that are threatened by overbuilding, because these wetlands serve as natural barriers to storm surges.

They built only on high ground, mostly left the river to its own devices, and relied on the wetlands as a natural barrier to buffer and deplete any incoming hurricanes.
