How did the ecological civilization policy rebuild the Human-Water
Relationships in the 600-year old “Tunpu” area, China?
Abstract
With the intensification of climate change and population growth,
human-water relationships (HWR) have changed from the simple utilization
of water resources to changing the spatial distributions and
distribution proportions of water resources through formulating
corresponding policies, such as Chinese ecological civilization policy.
However, the impact of the ecological civilization policy on the
evolution of HWR is still unclear. Here, taking the 600-year old
“Tunpu” area as a typical study area, this research analyses the
evolution of HWR over different space and time spans based on the Remote
Sensing Hydrological Station (RSHS) technology, an improved water
balance formula and the transition theory. The results show that at the
village scale, the water cycle structure of a typical village has
remained stable, and deforestation has increased the proportion of
runoff to precipitation by 10.62%. At the basin scale, due to land
use/cover changes and precipitation fluctuations, the trend of the
runoff changes from slowly decreasing to accelerated increases, with
change rate increasing from -0.073×104 m3·a-1 in the Ming Dynasty
(1470-1636) to 30.946×104 m3·a-1 in the China stage (1949-2020). HWR
have developed from the initial balanced resource-rich period to the
unbalanced extensive-development period and have finally changed into a
rebalancing period under the influence of the ecological civilization
policy. Four stages of HWR are as follows: predevelopment (1470-1685),
take off (1685-1912), acceleration (1912-2000) and rebalancing
(2000-2020). This research indicates that the ecological civilization
policy can rebuild HWR, and it is expected to provide enlightenment for
future construction of the ecological civilization.
