Abstract:[Objective] To analyzed the grades of the influence of production and constuuction projects on soil and water loss in order to provide a basis for developing an innovation management mode. [Methods] The 2 227 projects were selected from 31 production and constuuction project types. The projects were divided into 5 grades such as the 1st grade(milder soil and water loss), the 2nd grade(mild soil and water loss), the 3rd grade(moderate soil and water loss), the 4th grade(severe soil and water loss) and the 5th grade(extremely severe soil and water loss) according to the consultation with specialists and fuzzy cluster analysis. [Results] The category of the industry involved showed different grades: highway, railway, strip mine project, forest-paper integration project belongs to the 5th grade; airport engineering, nuclear power plant engineering, hydro-junction projects, water conservancy hub project, hydropower engineering, industrial park project belongs to the 4th grade; water-transportation industry, wind power industry, water diversion engineering, mining engineering, oil and gas exploitation engineering, rail transit engineering, development engineering in agriculture, forestry, thermal power industry belongs to the 3rd grade; irrigation projects, embankment engineering, storage-flood area, other small water conservancy engineering, oil and gas storage and processing engineering, network engineering, manufacturing industry, power transmission and transformation project belongs to the 2nd grade; real estate project, other urban construction, social undertakings, information industry and other industry belongs to the 1st grade. [Conclusion] Because the data collection of the influence of projects on soil and water loss is reliable, the divided influence grades of soil and water loss can accurately reflect the potential risk of soil and water loss for different industries.
