1 General
1.0.1 In order to implement the strategy of rural revitalization, standardize the technical requirements of village improvement work, improve the production and living conditions of farmers, improve the quality of living environment in rural areas, guide a new way of modern life in rural areas, and promote the comprehensive and coordinated development of rural society, economy and environment, develop this standard.
1.0.2 This standard applies to the improvement of human settlements in existing villages across the country.
1.0.3 Village improvement projects should include safety and disaster prevention, roads, bridges and traffic safety facilities, water supply facilities, drainage facilities, garbage collection and treatment, sanitary toilet renovation, public environment, village greening, pits, ponds and rivers, village buildings, historical culture Heritage protection, inheritance of local characteristics, energy supply, etc.
1.0.4 The village renovation should comply with the following basic principles.
1 Adapt measures to local conditions and advance in an orderly manner. According to the local economic and social development level of the village, farmers' production methods and living habits, combined with the long-term trend of the village's population and economic development, scientifically formulate the annual plan for village renovation. Prioritize the rectification of poor villages and the most urgent needs of villagers and the most basic facilities and related projects in rural areas.
2 Pay attention to protection and retain nostalgia. Protect the natural ecological environment and historical and cultural heritage of villages, inherit and carry forward traditional culture, and reshape the relationship between rural farming and civilization in the original ecology.
3 The villagers are the main body and stimulate motivation. To respect the wishes of the villagers and protect the rights and interests of the villagers, it is advisable to establish a mechanism of collusion, joint construction, joint management, joint evaluation, and sharing of all parties through the combination of government assistance, villagers' independent participation, and social forces' intervention, so as to jointly promote the improvement of rural human settlements. Improvement in remediation.

3 Safety and Disaster Prevention
3.1 General provisions
3.1.1 The impact of disasters such as earthquakes, fires, floods (waterlogging), geological disasters, wind disasters, lightning strikes, snow disasters, and freeze-thaw disasters should be comprehensively considered for village renovation, and the policy of focusing on prevention and combining prevention, resistance, avoidance, and rescue should be implemented. Adhere to the principles of comprehensive disaster prevention, group prevention and group governance, regional coordination, and people-oriented principles to ensure the safety of people's lives and the sustainable development of villages.
2 Villages should fully assess the impact of earthquakes on flood control works, and the design of flood control works should comply with the relevant provisions of the current industry standard "Code for Seismic Design of Hydraulic Structures" SL 203;
3 For secondary disaster sources caused by earthquakes that may cause fires, explosions, and spills of highly toxic, bacteria, and radioactive substances in production and storage units, move out of the village or take measures to prevent the spread of disasters.
3.4.3 The improvement of wind disaster prevention and mitigation in villages should be carried out according to the overall arrangement of the impact of wind disaster hazards, and the following regulations should be met.
1 The site selection of village construction land in areas with risk of wind disasters of category C and D should avoid areas that are prone to wind disasters, such as valley passes and mountain passes that are in line with the wind direction;
2.The selection of tree species for greening inside the village shall meet the requirements of resisting the frontal attack of wind disaster;
3 Wind prevention and disaster mitigation measures should be based on the impact of wind disasters, according to the requirements of wind disaster prevention and engineering wind protection measures, and make overall arrangements for construction land, construction projects, rural infrastructure, and non-structural components. For villages in areas at risk of typhoon disasters, comprehensive consideration should be given Disaster prevention requirements such as strong winds, wind waves, storm surges, rainstorms and floods that may be caused by typhoons;
