County and rural level territorial space planning optimization method and system

The invention provides a county and rural level territorial space planning optimization method and system, relates to the technical field of territorial space planning, and solves the problem that simulation of sun irradiation cannot be realized through structural improvement so as to realize reasonable control and adjustment of building spacing; and rotary air injection cleaning of dust of an irradiation lamp and a building model cannot be realized while illumination simulation is realized. The county and rural level territorial space planning optimization system comprises a table body; a building model is installed on the table body, an irradiation structure is further installed on the table body, and a cleaning structure is installed on the irradiation structure. Through the arrangement of the protection plates, the protection plates are in sliding connection with the sliding holes, the protection plates are located above the sliding rods, and the protection plates form a collision protection structure of
