Investigation and evaluation of groundwater pollution in North China Plain: This project is a geological survey plan project, and the project leader is Zhang. Main participants: Fei Yuhong, Li, Wang Zhao, Chen Jingsheng, Through the detailed study of groundwater pollution investigation, sampling and testing technology, the sampling equipment is developed, the organic pollution analysis and testing system is established, and a new evaluation method is put forward. Based on the investigation of groundwater pollution in North China Plain 1: 25000 km2 and key groundwater pollution areas 1: 50000 km2, it is found that 36.49% of groundwater can be directly drunk without any treatment, 24.25% can be drunk after proper treatment (Ⅳ), and 39.26% can be drunk. The characteristics of groundwater pollution in North China Plain are as follows: there are many pollution detection indexes, but few exceed the standard; (2) Most of them are point pollution, which is widely distributed and concentrated in the periphery of the city and the heavy chemical industry development zone and the affected area; ③ Shallow groundwater pollution is dominant. The project achievements were selected as the top ten scientific and technological progress in geological society of china in 2009.

Project results
Investigation and evaluation of groundwater pollution in the Pearl River Delta: Professor Sun Jichao is in charge of the geological survey project, and the main members are Jing, Huang, Liu, Chen, Wang and Xiang Xiaoping. The project explored the workflow, technical methods and mapping contents of groundwater pollution investigation and evaluation, completed the zoning of groundwater pollution prevention and control, and compiled a series of innovative maps of groundwater pollution prevention and control. We independently developed fixed depth sampling equipment and obtained national patents, and innovatively put forward a "graded ladder" groundwater pollution evaluation method, which provided a scientific basis and application platform for groundwater pollution prevention and control in this area, and also provided experience and demonstration for other similar areas in China to carry out groundwater pollution investigation. The planned projects and special research results are evaluated as excellent, which is the first time that China has completed the investigation and evaluation of regional groundwater pollution.
Evaluation and regionalization of geothermal resources in China: Geological survey project, presided over by researcher Wang Guiling, with members including Lin Wenjing, Chen Dehua, Liu Zhiming, Chen Hao, Zhang Wei and Yang Huifeng. The project collected and summarized the development and utilization data of geothermal wells and hot springs in 3 1 province (city, autonomous region) in China, revised the map of China's geothermal resources utilization status and the map of China's geothermal resources distribution, compiled the Technical Specification for Shallow Geothermal Energy Exploration and Development, and completed the Technical Requirements for National Geothermal Resources Status Evaluation and Zoning. This paper puts forward the calculation method of geothermal exploitable resources in convective sedimentary basins in mountainous areas of China, and puts forward suggestions and work arrangements for further exploration and evaluation of geothermal resources in China.

Investigation and evaluation of groundwater resources and its environmental problems in Hetao plain: geological survey project, the project leader is a researcher and professor, and the main members are Liu Haikun,,,, Chen, etc. In 2009, 1: 1 10,000 Quaternary geological and hydrogeological survey, hydrogeological geophysical exploration and drilling, test analysis, remote sensing interpretation and other work were carried out in Hetao Plain, and the situation of land use, salinization, desertification and endemic diseases related to geological environment in the survey area was understood in detail. A field test site for water and salt migration in vadose zone was established. This paper summarizes the problems existing in the established groundwater model in Hetao Plain, puts forward the modeling idea, and initially establishes the optimal allocation model of regional water resources. At the same time, the groundwater isotope profile and socio-economic database system in Hetao plain area are established, which lays the foundation for the study of groundwater cycle evolution.

Causes and Prediction of Erosion in the Bedrock Area of the Yellow River Basin: A social welfare project of scientific research institutes of the Ministry of Science and Technology presided over by Shi Jiansheng and Ye Hao. Main completion personnel: Hou, Shi Yingchun, Guo Jiao, Wu and Wang Qiangheng. The main research content is the erosion mechanism of soft sandstone. After three years' research, the project shows that pink sandstone has the strongest anti-erosion ability, while gray-white and purple-red sandstone has the weakest anti-erosion ability. Using "3S" technology, the erosion of soft sandstone ditch edge is predicted. The prediction results show that the erosion of soft sandstone is not only related to the stratigraphic combination of rocks, but also to the thickness and looseness of surface overburden. On the basis of existing soil and water conservation projects, it is suggested that different types of sand cover on the surface should be mainly treated to reduce the intensity of soil erosion in this area.
