Continuous urban growth, agriculture, and storm surges all contribute to devastating amounts of vegetation and habitat loss, as well as annual flooding along the shoreline of Colombia.
持续的城市增长、农耕、飓风以及哥伦比亚海岸线每年爆发的洪水，都使得极大程度上的植被与生境丧失。

This result shows that low concentration crosslinking polymer flooding can realize continuous injection with big slug and has a good potential of application.
试验证明低浓度交联聚合物驱能够实现大段塞连续注入，具有良好的应用前景。
