In fact, with the position and the distribution in Vietnamese economy, the Red River Delta has an important role. People are trying to understand more about the formation of the Delta. The natural environmental conditions in present years in the Red River Delta have being considered and researched properly. There is a relation between the geological position, river dynamics, climate and formation of the Delta. With the influence of the embankment system had been set up from a lomg time, the formation of the Delta has been affected by humans activities. As a result, there is a mangrove forest and mangrove ecosystem in the river mouths. Sea level changing had had a relation with the formation of the Delta, now it also affects on the coastal area, changes the coastline by erosion. Climatic changes with the impact of global warming affect directly on the environmental condition of the low land in the coastal area. The lack of precipitation in summer causes the decrease in river discharge, was followed by the salinity intrusion in the river mouths changing in the coast, in where there is increase in sea product cultivation's square. It is necessary to study and research about, the changes of natural environment, gain knowledge and estimate its influences. It also helps people to live in matural environment and improve it.

事实上，从红河三角洲在越南经济中的地位和分布来看，它具有重要的作用。人们正试图了解更多关于三角洲的形成。充分考虑和研究了红河三角洲近年来的自然环境条件。三角洲的形成与地质位置、河流动力、气候等因素有关。在长期筑堤体系的影响下，三角洲的形成受到人类活动的影响。因此，河口地区形成了红树林和红树林生态系统。海平面的变化与三角洲的形成有关，现在它也影响到海岸带，通过侵蚀改变海岸线。气候变化与全球变暖的影响直接影响到沿海地区低地的环境状况。夏季降水偏少导致河流流量减少，河口盐度入侵，沿海地区海产品养殖面积增加。有必要对自然环境的变化进行研究和探讨，了解自然环境的变化，评估自然环境的影响。它还帮助人们生活在自然环境中并改善它。
