T/XZBX 0195-2026 Guidelines for the application and effectiveness evaluation of ecological restoration techniques for degraded forest land
Basic Information
Scope
Degraded forestlands refer to types of forestlands that are damaged due to the combined effects of natural disturbances and human activities, resulting in impaired forest vegetation structure, deteriorated soil physicochemical properties, reduced water conservation and biodiversity functions, and significantly reduced ecosystem stability and service functions. Degraded forestlands are widely distributed in areas such as logged-over lands, low-efficiency degraded forests, fire-damaged lands, heavily infested forests, lands surrounding mining and engineering disturbance areas, and areas prone to water and soil erosion. Their formation mechanisms are complex, with significant differences in degradation levels, and they are characterized by long recovery periods, high risk uncertainty, and high management costs. If restoration measures are improperly selected or management is inadequate, this may lead to slow vegetation recovery, secondary degradation, invasive species infestation, exacerbated soil erosion, and difficulty in achieving stable improvement in ecological functions. In the context of the "Integrated Protection and Systematic Governance of Mountains, Water, Forests, Fields, Lakes, and Deserts" and the precise improvement of forest quality, ecological restoration of degraded forestlands requires an ecosystem-based approach, adhering to the principles of near-natural restoration and adaptive management. It should comprehensively consider site conditions, degradation types, disturbance factors, target functions, and regional ecological security patterns, and adopt a comprehensive technical system combining engineering measures, biological measures, and management measures to gradually restore vegetation structure, improve soil quality, and enhance ecosystem stability and service functions. At the same time, impact evaluation is an essential component of ecological restoration. A scientific, quantifiable, comparable, and traceable indicator system and evaluation
