Heilongjiang (abbreviated as: Hei) is a provincial administrative region of the People's Republic of China, , and the provincial capital Harbin. Heilongjiang is located in the northeastern part of China, and is the northernmost and eastern part of China's land. It is across the river from Russia in the north and eastern part, adjacent to Inner Mongolia Autonomous Region in the west, and borders Jilin Province in the south; the total area is 473,000 square kilometers. In 2020, Heilongjiang Province has 12 prefecture-level cities and 1 region, with a total of 54 municipal districts, 21 county-level cities, 45 counties and 1 autonomous county. Heilongjiang Province is a heavy industrial base in China and an important commercial grain base in China. It is named after Heilongjiang to the north of the province.
12 cities: Harbin City, Qiqihar City , Jixi City , Hegang City , Shuangyashan City , Daqing City , Yichun City , Jiamusi City , Qitaihe City , Mudanjiang City , Heihe City , Suihua City .
geological map is a graph that uses a certain legend to represent various geological and geological phenomena on a certain scale topographic map using a certain legend. It is a general term for maps that represent lithophagocytics, lithologies, stratigraphic age, geological structure, magma activities, mineral distribution, etc.
The compilation of geological maps is mostly based on actual measured data, and there are certain mapping specifications and standards. The strata grading system used at present, the color marks and symbols representing the age of the strata, and the color marks and codes representing various rock bodies are mostly internationally common. Objective needs to promote the development of geological maps towards specialization and departmentalization. The types are also divided into smaller and thinner. In addition to ordinary basic geological maps, there are also Quaternary geological maps, earth tectonic maps, lithophagomatic maps, paleogeographic maps, hydrogeological maps, engineering geological maps, mineral distribution maps, etc.
Geological disasters refer to geological effects or geological phenomena formed under the action of natural or man-made factors, causing losses to human life and property, and causing damage to the environment. The distribution and change laws of geological disasters in time and space are both subject to the natural environment and are related to human activities, and are often the result of the interaction between humans and nature.
natural disaster , which is mainly caused by geological dynamic activities or abnormal changes in the geological environment. Under the influence of the internal, external, or artificial geological dynamics of the earth, abnormal energy release, material movement, , deformation and displacement of rock and soil, and abnormal environmental changes, etc., which endanger human life, property, life and economic activities or destroy the resources and environment on which humans rely on for survival and development. Undesirable geological phenomena are usually called geological disasters. They refer to geological events that deteriorate the geological environment caused by natural geological effects and human activities, reduce environmental quality, directly or indirectly endanger human safety, and cause losses to social and economic construction.
The spatial distribution data of more than 250,000 geological disaster points nationwide released by the geographical remote sensing ecological network platform , including collapse, collapse, mudslide , ground settlement , ground cracks, landslides, and slopes. The data is divided into 30 provinces, cities and autonomous regions across the country, and the data format is excel and vector shape file formats.
