Table 2 Meaning, dimensions, and scales of evaluation indicators
From: Assessment of ecological and landscape services in urban green spaces in South China Karst
Evaluation indicators | Meaning | Dimensions | Scale |
|---|---|---|---|
CSOR | Plants have the ability to sequester carbon and release oxygen. | One-dimensional | Urban area |
WC | UGSs have the ability to retain water. | ||
AC | UGS ecosystems have the ability to purify, filter, and decompose pollutants in the atmosphere, which mostly include sulfur dioxide absorption (SDA), nitrogen oxides absorption (NOA), and dust retention (DR). | ||
SC | The ability of UGS to prevent soil erosion and intercept sediment. | ||
BC | UGS provide habitats and breeding grounds for flora and fauna, promoting urban biodiversity. | ||
GSA | The relative or absolute ease of overcoming spatial resistance to reach a green space from any point in space, and a measure of the level of service of a UGS layout. | Two-dimensional | Urban area/communities |
GVI | The ratio of green landscape within the human field of vision can reflect the effect of green landscape at the three-dimensional spatial level and measure the intuitive feeling of people on urban greening71. | Three-dimensional | Human |
RS | Residents’ subjective evaluation of the green space’s quality provides a real representation of the population’s contentment with its overall state. |
