This year, floods occurred in many places in Heilongjiang, bringing huge losses to the local people. For a while, the debate about whether such a disaster was a natural disaster or a man-made disaster spread in society. However, from many observations, it is clear that this flood disaster is both a natural and a man-made disaster.

First of all, the natural disaster factor cannot be ignored. The main cause of this year's flooding in Heilongjiang is continuous and intense rainfall, which is beyond the control of nature. The weather forecasting department made a disaster warning in advance, but because the weather changed very drastically, the forecast results were not accurate, and the disaster situation was accurately assessed. This sudden extreme weather phenomenon makes people have to face the dilemma in front of them.

However, human factors play an important role in flooding. First of all, unreasonable urban planning is one of the important causes of local flooding. For a long time, in the process of urbanization, some cities have attached importance to economic benefits and neglected the protection of the ecological environment, and built a large number of high-rise buildings and landfills, hindering the normal operation of water flow. This not only exacerbates surface runoff, but also causes the groundwater table to rise, which in turn causes flooding.

Second, poor management of reservoirs and levees is also a cause of flooding. Before the disaster, many reservoirs and dikes were close to saturation, and there were still some hidden dangers, such as aging structures. However, the failure of the relevant authorities to take timely measures for maintenance and investigation has increased the risk of flooding and further expanding flooding.

In addition, the imperfection of farmland water conservancy facilities is also one of the causes of disasters. A large amount of farmland does not have a well-drained system, and if it encounters continuous rainfall, it will lead to the flooding of crops and large areas of farmland. If the drainage system of farmland is fully improved and improved, the damage caused by flooding can be reduced.

To sum up, the floods in many places in Heilongjiang this year are both natural and man-made disasters. Although technical means such as weather prediction and disaster warning need to be further improved, we cannot ignore the impact of human behavior in front of the natural interface. We must carry out comprehensive management in many aspects, such as planning cities, managing reservoirs, and improving farmland water conservancy facilities, so as to reduce the occurrence of disasters and protect people's lives and property. At the same time, it is also necessary to enhance the public's awareness of disaster prevention and self-help ability through measures such as strengthening disaster education and emergency drills, so as to jointly cope with the challenges brought by natural disasters to our lives.
