Abstract
Agricultural water is the largest water user in Yantai City, and its water consumption accounts for more than 2/3 of the total water consumption in Yantai City. The potential for agricultural water saving is huge, but the overall level of agricultural water efficiency in Yantai City is not very high, and the waste of water resources is serious. Efficient agricultural water use in Yantai is a key issue for achieving efficient and sustainable use of water resources in Yantai. Different regions in the study area have different social and economic developments, different industrial structures, and different natural climates, and their investments in agricultural water conservancy facilities are also different. In order to better study the agricultural efficient water use model in Yantai City. This article will divide the agricultural irrigation sub-area according to the actual situation of Yantai.
Highlights
Yantai is a typical coastal water-scarce city
When the water use gap is large, agricultural water use is often squeezed out first. It can be seen from the table that even in the year of abundant water, the actual agricultural water consumption in Yantai City only accounts for 42% of the planned water consumption; the extremely dry year such as 2000 only accounts for 27% of the planned water consumption
IV area: Belongs to continental monsoon type subhumid climate, annual average precipitation 686 mm.The terrain is high in the north and low in the south, with hills and hills accounting for 67.4% of the total area.Yantai city is a vegetable base, food crops large farmers.IV area in recent years, vegetable production in about half of Yantai production, food production accounted for Yantai more than 30% of the total grain output.The overall proportion of high-efficient watersaving agricultural irrigation area is small
Summary
Yantai is a typical coastal water-scarce city. When the water use gap is large, agricultural water use is often squeezed out first. It can be seen from the table that even in the year of abundant water, the actual agricultural water consumption in Yantai City only accounts for 42% of the planned water consumption; the extremely dry year such as 2000 only accounts for 27% of the planned water consumption. Agricultural water consumption continued to grow negatively, effectively alleviating the city’s water shortage. The form of agricultural water use is still grim, the phenomenon of waste still exists, and the efficient use of water in agriculture needs to be strengthened.
