This invention relates to the field of road landscape planning technology, and more particularly to a road landscape planning method, apparatus, electronic device, and storage medium. The method first obtains multiple first node vectors; then, with the goal of minimizing intra-class differences and maximizing inter-class differences, the multiple first node vectors are classified, and the road is divided into multiple first ecologically sensitive sections based on the classification results; next, for each first ecologically sensitive section, a viewpoint analysis is performed using a geographic information system to obtain the road landscape planning scope, and plant diversity analysis is performed based on the road planning scope to obtain multiple ecological plots; finally, for each ecological plot, landscape planning is carried out based on ecological base data and sensitive characteristics. This invention defines the planning scope based on GIS viewpoint analysis, combines plant diversity clustering with plot adaptation, prioritizes the preservation of native vegetation, avoids the invasion of alien species, and maximizes the protection of the integrity of the surrounding ecosystem.

The invention discloses a bare high and steep slope restoration plant community construction method, which comprises the following steps: selecting sample plots with different restoration degrees in an area where a target slope is located, and performing succession community feature investigation in the target area; performing region division and succession stage division on the selected sample plots with different recovery degrees; establishing a species fitness comprehensive model, and screening matched species; determining an indigenous plant combination strategy in each succession stage; planting the indigenous plants in succession stages, and carrying out acceptance assessment. According to the method, plants are configured by stages according to the natural succession law, community degradation caused by species mismatch is avoided, and the requirement for later manual intervention is reduced; according to the method, accurate model selection is carried out according to microenvironment differences between surface soil and cracks, and the adaptability of plants to extreme habitats is greatly improved; according to the method, indigenous plants serve as cores, the invasion risk of alien species is avoided, the fusion degree with a local ecological system is high, and the long-term maintenance cost is remarkably reduced.
