Practice and Reflection on the Technical Specification for Soil and Water Conservation of Urban Production and Construction Projects in Xi'an City
The Technical Specification for Soil and Water Conservation of Urban Production and Construction Projects(DB6101/T 3094-2020)(hereinafter referred to as the Specification)proposed by the Xi'an Water Affairs Bureau was released on December 23,2020 and officially implemented on January 23,2021.Specification guided soil erosion and water loss prevention and control work of real estate engineering,municipal engineering and public service production and construction projects that may cause soil erosion and water loss within the urban built-up and planning areas of Xi'an City,refined the objectives of soil erosion and water loss prevention and control,optimized the project overview,improved the evaluation of soil and water conservation in the main project,and strengthened the design of soil and water conserva-tion measures system.In the past three years of the implementation of Specification,more than 2 000 urban production and construction pro-jects have been guided in the preparation of soil and water conservation plans and facility acceptance work.About 83%of production and construction projects in Xi'an have increased the scale of green space construction,about 61%of projects have reduced runoff losses,and a-bout 54%of projects have reduced the risk of soil erosion and water loss.The average annual runoff loss of production and construction pro-jects in Xi'an has decreased by 35 800 m3,and the average annual soil erosion has decreased by 169.05 t.The urban soil and water conser-vation work has achieved significant effects.
