Liaohe Plain

Liaohe Plain is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Liaohe Plain rather than just read about it. In short: The Liaohe Plain is a paddy plain located in the southern tip of Northeast China, part of the greater Northeast China Plain. 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.

Key takeaways

Liaohe Plain belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Liaohe Plain to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Liaohe Plain from memory before moving on to harder problems.

Reference excerpt

The Liaohe Plain is a paddy plain located in the southern tip of Northeast China, part of the greater Northeast China Plain. 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.

Location Liaohe is located in China's golden belt of maize production, and serves as a strategic commodity grain base. 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. 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. The adjacent Liaohe River Basin is one of the most vulnerable areas to climate change in China and is also important to grain production in Inner Mongolia.

Worked examples

Example 1 — a first encounter with Liaohe Plain

Start with the simplest possible case. Write down what Liaohe Plain claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Liaohe Plain before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Liaohe Plain ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Liaohe Plain

In research: Liaohe Plain appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Liaohe Plain in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Liaohe Plain is common in secondary-school and first-year university syllabi. It links to neighbouring topics Agriculture in China, China geography stubs, Geography of Liaoning, so understanding it makes those chapters shorter.
In everyday life: Look for Liaohe Plain outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
