This invention discloses a method and system for land resource spatial utilization planning, relating to the field of land planning. The method includes: acquiring relevant data of the planning area and performing standardized processing; constructing spatiotemporal land use units containing a time dimension based on a time-division strategy; receiving temporary land use event information and mapping it to corresponding spatiotemporal land use units; performing conflict verification based on preset constraint rules and generating permit determination results; comprehensively evaluating and ranking candidate schemes that pass the verification; and outputting temporary land use permit results, a control list, and audit logs. The system includes a data management module, a spatiotemporal unit construction module, a rule engine module, a ranking and evaluation module, and a result output module. This invention achieves integrated management of spatial and temporal dimensions, supports dynamic planning and risk identification driven by temporary land use events, and improves the standardization and traceability management level of land resource spatial utilization.

This invention relates to the field of testing technology, and provides a sample reduction apparatus and method. The sample reduction apparatus includes: a reduction device comprising: a dispensing bin, a dispensing wheel, a first driving component, a stage, and a second driving component; the dispensing bin has a material cavity and an inlet; the dispensing wheel is rotatably disposed in the material cavity, and, in conjunction with the side wall of the material cavity, divides the material cavity into multiple sub-cavities; the dispensing wheel has a cavity and multiple outlets communicating with the cavity; the first driving component is drivenly connected to the dispensing wheel; the stage is provided with multiple material grooves for communicating with the sub-cavities; the second driving component is drivenly connected to the stage and is used to drive the stage to switch between multiple stations; a mixing device is disposed above the reduction apparatus. The sample reduction apparatus provided by this invention can achieve differentiated and programmable sample allocation, and the sample meets the requirements for subsequent testing after a single reduction, reducing manual operation steps and waiting time, and improving processing throughput.

This utility model belongs to the field of seedling transplanting technology, and relates to a mechanical clamp for preventing damage during the transplanting of vegetable plug seedlings. It consists of a support component, a transplanting component, a limiting component, a control component, and a reset component. The support component provides basic support for operation, the transplanting component grips the seedling, the limiting component ensures stable sliding of the transplanting component, the control component controls the movement of the transplanting component, and the reset component resets the control component. This mechanical clamp solves the problems of unstable seedling gripping, inconvenient transplanting operation, and easy damage to seedlings and plugs during the transplanting of vegetable plug seedlings, thus improving the efficiency and quality of vegetable plug seedling transplanting.
