[0047] Example 2 Suitability assessment of planting paulownia on the north and south sides of Tuancheng Road, Haidian District, Beijing

[0048] (1) Investigation of the site environment conditions of the planned planting of plane trees on the south and north sides of the road

[0049] The south side of the road is the residential area, and the main shelter is the community wall with a height of 4m; the distance between the fatong on the south side of the road is 1.5m from the wall; the planting position on the north side of the road is 27m from the south wall.

[0050] (2) Calculate the tan value a of the solar altitude angle at noon on the local winter solstice day 1 And the tan value a of the solar altitude angle at noon on the Awakening of Insects day 2

[0051] The points of direct sunlight at noon on the winter solstice and the day of the Jingzhe are respectively 23.43° south latitude and 4° south latitude. The latitude of the Beijing area is about 40°. point latitude...

Embodiment 3

[0058] Example 3 Suitability assessment of planting paulownia on the north and south sides of the east-west road in the second district of Yongwangjiayuan, Haidian District, Beijing

[0059] (1) Investigation of the site environment conditions of the planned planting of plane trees on the south and north sides of the road

[0060] The south side of this section of road is the residential area, and the main shelter is the community building, which is about 28m high; the Fatong on the south side of the road is 21m away from the community building; the planting position on the north side of the road is 33m away from the south wall.

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...
