The invention relates to the technical field of urban ecological engineering, in particular to a parking lot authigenic plant planting method based on carbon immobilization. The invention provides a parking lot authigenic plant planting method based on carbon immobilization, which is characterized in that a three-stage ecological rotation mechanism is introduced into vegetation construction according to the sequence of a pioneer plant period, a green manure turning and pressing soil returning period and an authigenic plant community succession period to form a parking lot authigenic plant pool, and the parking lot authigenic plant planting based on carbon immobilization is realized. The invention aims to improve the greening ecological benefit and carbon sink capacity of the parking lot by optimizing the soil structure and adopting the crop rotation technology, provides a plant pool structure which adapts to the environment of the parking lot, has high-carbon solid storage capacity and can realize autonomous ecological circulation, and improves the soil health, inhibits diseases and prolongs the plant coverage period through the crop rotation technology. The problems that traditional parking lot greening depends on manual intervention, and the carbon sink benefit is low are solved, and continuous carbon sink under the low maintenance cost is achieved.

The present application relates to ecological slope protection, a method for establishing a rainwater infiltration control model based on the same, and a control method, and belongs to the technical field of urban construction. The slope protection comprises a water-permeable layer, a reinforcing layer, and a plant cover layer stacked in sequence. The water-permeable layer is fixed on the surface of the slope soil. The root system of the plant cover layer penetrates the reinforcing layer and the water-permeable layer in sequence and is rooted in the slope soil. The water-permeable layer comprises a gradient porous ceramic layer and a polymer water-conducting fiber layer. The gradient porous ceramic layer is close to the reinforcing layer. A humidity sensor sub-network is arranged at the junction of the reinforcing layer and the plant cover layer and at the junction of the water-permeable layer and the reinforcing layer. Pressure sensors are arranged at the top and bottom of the polymer water-conducting fiber layer. A rain sensor is arranged in the open area at the top of the slope. The bottom of the polymer water-conducting fiber layer is provided with a plurality of water-conducting pipes. Side water-conducting valves are arranged on the water-conducting pipes. The present application realizes multiple infiltration paths for rainwater and solves the problem of the conflict between root system infiltration and the direction of infiltration and the gravitational field in traditional slope protection.

The application belongs to the technical field of rock painting identification, and particularly relates to a rock painting identification method, comprising the following steps: obtaining rock painting incision depth information; judging the positive and negative values of the incision depth information based on an incision depth model; if the value is positive, marking the incision depth information as invalid incision; if the value is negative, marking the incision depth information as valid incision; obtaining rock painting incision position information; based on a rock painting incision position model, pre-processing the valid incision, and outputting a rock painting basic sample; based on a rock painting information library, comparing the similarity of the rock painting basic sample, and outputting a rock painting number. The incisions on the rock painting at the damaged part are marked as valid and invalid, then the valid incisions are connected with the incisions that are not damaged and accurate, and then the incisions are compared with the information of the previous general survey, so that the problems that professional personnel are difficult to identify due to long interval time, sand covering, plant covering, human damage and the like, and the problems that search cannot be found or too many similar search results exist are solved.
