Problems solved by technology

Therefore, when studying the morphological characteristics of urban green space and its impact on the urban environment, the characteristics of urban green space changes over time should be considered. Currently, only the morphological characteristics of green space at a certain moment are obtained in the current study, and there is no method for establishing a dynamic model.

Abstract

The invention discloses a method for constructing an urban green land form dynamic three-dimensional database. The method comprises the following steps of: obtaining each green land form unit surfaceelement of an urban green land; establishing a plane attribute table of each greenbelt form unit surface element; establishing a height attribute table of each greenbelt form unit surface element; establishing a structure attribute table of each greenbelt form unit surface element; calculating a crown volume index of each greenbelt form unit surface element; calculating a leaf area index corresponding to each month of each greenbelt form unit surface element; and constructing a visual urban green land form dynamic three-dimensional database on an ArcScene platform. According to the urban greenland form dynamic three-dimensional database construction method, the three-dimensional form of the urban green land can be presented, and the three-dimensional form can be dynamically changed alongwith time.

Description

technical field [0001] The invention relates to a method for building a three-dimensional form database, in particular to a method for building a dynamic three-dimensional database for urban green space forms. Background technique [0002] With the advancement of global urbanization, 55% of the world's population lives in cities, and it is expected to reach 68% in 2050. Although cities provide benefits and opportunities for people, they also face serious environmental problems, such as urban heat islands, increased energy consumption, flooding, air pollution, loss of biodiversity, etc. Urban green space is an indispensable part of the city and an important functional system that regulates the urban environment and provides livable space for urban residents. The wide-ranging environmental benefits provided by urban green spaces include storing carbon and removing air pollutants, reducing noise pollution, stormwater management, regulating ambient temperature, reducing the ris...
