Land pressure evaluation in the Yangtze River Delta region: A
perspective from production-living-ecology
Abstract
The limited land is under unprecedented pressure from production, living
and ecology. In order to evaluate the land pressure in the Yangtze River
Delta region in 1995, 2000, 2005, 2010, 2015, and 2020 from the
perspective of production, living, and ecology. This study builds a land
pressure evaluation index system based on a fuzzy comprehensive
evaluation model using multi-source and multi-scale data. In order to
investigate trade-offs and synergies among production, living, and
ecology pressures, we use the mechanical equilibrium model in physics.
We then analyze land pressure model reliability and uncertainty using
Monte Carlo simulations. The results show that (1) Our model can
effectively reveal the level of land pressure and reflect the land
pressure geographical pattern of “high in the east and low in the west,
high in the south and low in the north” that characterizes the Yangtze
River Delta region. (2) While living and ecology pressures are tending
to rise, production pressures are tending to decrease. (3) Except for
Shanghai, the trade-off areas are primarily concentrated in economically
successful regions with high production and living pressure and low
ecology pressure. The coordinated areas are primarily found in northern
Jiangsu Province and northern Anhui Province.
