Abstract

The invention provides a landscape ecological efficiency evaluation method for urban greenbelt planning. The method comprises the steps of collecting and preprocessing basic data; calculating a landscape pattern optimization index of urban greenbelt planning; calculating an ecological process optimization index of urban greenbelt planning; calculating a landscape ecological efficiency comprehensive optimization index of urban green space planning; and quantitatively evaluating the comprehensive optimization effect of the urban greenbelt planning landscape ecological efficiency. The quantitative evaluation method is provided for demonstration and selection of the urban greenbelt planning scheme, and scientificity and effectiveness of the urban greenbelt planning scheme are improved.

Description

technical field [0001] The invention relates to the fields of urban green space planning and environmental impact assessment, in particular to a landscape ecological efficiency evaluation method for urban green space planning. Background technique [0002] In recent years, the speed of urbanization in my country has been accelerating, which has brought increasingly prominent environmental problems and affected the sustainable development of cities. Urban green space and green infrastructure can provide urban residents with recreational places and commuting greenways, help optimize the urban spatial pattern, play ecological functions such as improving air quality, alleviating the heat island effect, regulating microclimate and hydrological processes, and promoting the physical and mental health of residents . Therefore, rational planning of urban green space and efficient construction of green infrastructure have become an important way for different countries and regions in...
