Ningbo City Greening Maintenance Grade Standard

"Ningbo Greening Maintenance Grade Standard" is a document that specifies the greening requirements and maintenance standards in different regions. According to the standard, the greening in Ningbo is divided into three levels: first, second and third. First-class greening mainly refers to the central city, important parks and green belts. And its greening requirements and maintenance standards are the most stringent, and it needs to achieve a certain beautification effect. Flowers and trees need to be planted in groups with a high proportion of varieties, shapes and colors. Secondary greening is in various areas of the city, such as greening, parks, green spaces, courtyards and so on. And the requirements for it are relatively low, mainly through the upper and lower parts. The proportion of trees and shrubs is 1: 1- 1.5, and the proportion of flowers and plants is small. Three-level greening refers to the fringe of the city or some less important green spaces. Greening requirements are low, but it needs to be kept clean and tidy. In a word, the establishment of Ningbo's greening maintenance grade standard aims to unify the standards of urban greening, improve the beauty and cleanliness of the urban environment, and let citizens live in a more comfortable and healthy ecological environment.
