| Abstract: |
| Based on the panel data of China's economic level and
green area from 2006 to 2019, the output of landscape waste in
China was calculated scientifically, and the dynamic and spatiotemporal characteristics of landscape waste generation were
systematically analyzed. At the same time, based on the solid state
effect model of IPAT and the logarithmic weight decomposition
method of Divisia, the contribution efficiency of four influencing
factors to the generation of landscape greening waste in China
was deeply explored. The results showed as follows: 1) Since
2006, the generation of landscape waste in China has increased
significantly, and the spatial pattern of different regions has
significant differences; 2) The economic factor (R), urban factor (I)
and green space factor (S) were the main driving factors affecting
the waste emission of landscaping, and their effects were in the
order of R>I>S. The economic factor and green space factor were
the promoting factors driving the generation growth. 3) According
to the analysis results of driving factors, each region can be divided
into four types according to the intensity of driving factors, among
which "balanced" development mode is the ideal one, and 38.7% of
cities are in "R-type" development mode. This study can provide a
scientific theoretical basis for the management of the whole chain of
landscape waste collection and treatment in China |
