A method for accurately evaluating the planting suitability of urban east-west road platanus orientalis in North China

Abstract

The invention discloses a method for accurately evaluating whether urban oriental and west roads in North China are suitable for planting Platanus orientalis. The method comprises the following stepsof (1) investigating site environment conditions of positions of to-be-planted Platanus orientalis on the south side and the north side of the oriental and west urban roads; (2) respectively calculating tan values a1 and a2 of the solar altitude at the noon of the local winter solstice day and the stunning day; (3) calculating the maximum shadow index b of the south side and the north side of theroad; and (4) analyzing data, evaluating and determining whether the method is suitable for planting of the platanus orientalis. The method is based on analysis of the shielding degree of the externalenvironment of the southern road to the rhizosphere soil of the oriental plane; the planting points are irradiated by sunlight; the ground temperature is taken as a focus point, the irradiation degree of sunlight on the plant tree hole position is taken as a direct index, finally, whether the northeast-west road of the North China is suitable for planting the tung tree or not is determined, so that tung tree planting in the northern China can be guided, and resource waste and economic loss caused by blind planting are reduced.

Description

technical field

[0001] The invention relates to a method for evaluating plant planting suitability, in particular to a method for accurately evaluating planting suitability of sycamores (Platanus orientalis Linn.) on east-west roads in cities in North China, and belongs to the field of planting sycamores. Background technique

[0002] Plane tree, also known as Platanus orientalis Linn., is one of the famous tree species for landscaping, and it is also one of the most popular tree species in North China because of its tall body, fast growth, good shading effect, resistance to pruning, beautiful tree shape, and few pests and diseases. A more common street tree. However, according to the investigation on the growth of Fatong in Beijing and other places, it is found that the growth of Fatong planted in North China has little difference between the east and west sides of the north-south road, and the growth difference between the north and south sides of the east-west road is obv...
