The agricultural areas in Nanjing are mostly located in low mountain and hilly areas
where the local water resources are scarce and unevenly distributed
causing them prone to drought disasters. After years of construction
Nanjing has formed a relatively complete drought disaster prevention system that combines engineering and non-engineering. Faced with a rare and severe drought in 2022
the overall grain production remained stable. Compared with the drought in 2011
the average yield per mu of summer grain increased by 13.6%
and there was no crop failure or significant economic loss. The normal living water supply of residents was not affected
and the drought prevention effect was significant. However
there are also problems such as low efficiency of water diversion from drought resistant water sources
insufficient capacity of water storage and turning projects
and the need to further enhance service guarantees. In order to better cope with increasingly frequent extreme weather and abnormal drought disasters
this article proposes relevant suggestions for strengthening drought resistance work in Nanjing from the aspects of modern water network pattern
source control of water sources
construction of water storage and conservation projects
and non-engineering measures
which can provide reference and guidance for drought prevention work.
