Abstract: OF THE DISCLOSURE 
The present disclosure relates to a method and system for measuring accessibility of an 
ecological effect of green space on building energy consumption carbon emission reduction. The 
method includes: determining a to-be-measured range based on a source-flow-sink theory; 
obtaining a supply of a carbon emission reduction-specific ecological service of a green space 
landscape pattern and a demand of a green space-based ecological service for building energy 
consumption carbon emission reduction; constructing a supply-demand mapping relationship 
table based on the demand of the green space-based ecological service and the supply of the 
carbon emission reduction-specific ecological service; determining, based on the supply-demand 
mapping relationship table, a service capability of providing a type-j ecological service by the 
green space landscape pattern; determining a type-i demand of a target building for the type-j 
ecological service; obtaining a spatial friction coefficient, and determining, based on the spatial 
friction coefficient, a cost distance from the target building to the place providing the type-j 
ecological service; and determining accessibility of an ecological effect of the green space 
landscape pattern by using an improved universal-gravitation potential model based on the 
service capability, the type-i demand, and the cost distance. The present disclosure realizes 
scientific and quantitative measurement of the ecological effect of the green space landscape 
pattern on building energy consumption carbon emission reduction.
