Embodiment Construction
[0030] Such as figure 1 Shown, the urban forest tree priority planting area selection method of the present invention comprises steps:
[0031] 1) Obtain the vector layer of the city, and then use the community (street) and / or village as the unit to divide the city into several regional units;
[0032] 2) Input the population data, road area data and real tree canopy coverage data of each regional unit of the city, and then use the database calculation function of the ArcMap GIS system to calculate the population density, road density and real tree canopy coverage of each regional unit the vector data;
[0033] 3) Using the database calculation function of the ArcMap GIS system, normalize the vector data of the population density, road density and actual tree canopy coverage of each regional unit (by using the maximum value normalization method), and obtain each regional unit The normalized population density, normalized road density and normalized real tree canopy coverage ...
