Abstract: The present disclosure provides an ecological governance method based on erosion prevention and control for a gentle slope farmland and relates to the technical field of ecological governance of farmlands. The ecological governance method based on erosion prevention and control for a gentle slope farmland includes the following steps: sampling a gentle slope farmland to investigate erosion thereof; and determining erosion of a gentle slope cultivated land and selecting a corresponding recovery strategy based on a detection result of a sample, a soil quality index (SQI), and a comprehensive vegetation quality index (VQI), where the recovery strategy includes a natural recovery method and a biological-farming comprehensive recovery method; enclosing the gentle slope cultivated land, fallowing the gentle slope cultivated land and reducing tillage; exterminating insect pests and poisonous weeds in the enclosed area; and turning over straws under soil by a cultivator. The growth of poisonous weeds is inhibited.

Abstract: This application discloses a method and an apparatus for processing a nuclear energy spectrum. The apparatus includes: a detector, a nuclear pulse processing module, and a nuclear energy spectrum processing module; the detector is configured to detect nuclear radiation and convert the nuclear radiation into nuclear pulse signals with corresponding amplitudes; the nuclear pulse processing module is configured to shape the nuclear pulse signals into narrow pulses, and perform amplitude analysis on the narrow pulses to generate the nuclear energy spectrum; the nuclear energy spectrum processing module is configured to reduce a value of an energy resolution of the nuclear energy spectrum to obtain the nuclear energy spectrum with the energy resolution of the reduced value.
