The embodiments of the present disclosure provide a system for calculating a regional crowd movement and a method thereof. The system is applied to a target monitoring environment, a plurality of key travel nodes are planned in the target monitoring environment, and the system includes radio frequency labels deployed on pedestrians, calculation apparatuses deployed at the key travel nodes and a plurality of directional antennas. The directional antenna is configured to, when driven by the calculation apparatus, send a read-write signal to the radio frequency label in a coverage region; the directional antenna is further configured to forward a radio frequency signal simultaneously reflected by the radio frequency label at the time of obtaining the read-write signal to the calculation apparatus; the calculation apparatus is configured to, based on a tempo-spatial distribution circumstance of the radio frequency signals in the region.

This disclosure provides a stress-responsive polypeptide sequence for fusion with a polypeptide to specifically induce stability of the fusion polypeptide under stress conditions, such as drought, high salt and high temperature, in plants. Also disclosed includes an expression vector for expressing a fusion polypeptide comprising the stress-responsive peptide in plants transformed therewith, and a method for generating a transgenic plant with enhanced tolerance to environmental stresses, comprising introducing into the transgenic plant a polynucleotide encoding a fusion polypeptide which comprises the stress-responsive peptide as disclosed and a plant anti-stress gene, such as the plant senescence-associated gene SSPP. A plant expressing the expression vector that have an enhanced stress tolerance, includingand soybean, is also provided.
