The Liaohe Plain is a paddyplain located in the southern tip of Northeast China, part of the greater Northeast China Plain.[1] The Liaohe Plain is one of the most important industrial zones in Liaoning, and with a cultivated land area of 144 million hectares, the area of the paddy-growing fields of its rice field station has increased by 977.1 sq km, from 1988 to 2006.[2][3][4]
Location
Liaohe is located in China's golden belt of maize production, and serves as a strategic commodity grain base.[4] Liaohe's average annual temperatures in January and July are −9.8 to 8.6 °C and 24.4 °C, with irrigation generally starting in early May.[1] Cultivation activity includes oil and gas exploration, aquaculture, and salt production. Excessive land usage contributes to the deformation of the plain, detrimental to the environment and economic construction projects.[3]
