Source-derived summary

The Sichuan Basin (Chinese: 四川盆地; pinyin: Sìchuān Péndì), formerly transliterated as the Szechwan Basin, sometimes called the Red Basin, is a lowland region in southwestern China. It is surrounded by mountains on all sides and is drained by the upper Yangtze River and its tributaries. The basin is anchored by Chengdu, the capital of Sichuan province, in the west, and the direct-administered municipality of Chongqing in the east. Due to its relative flatness and fertile soils, it is able to support a population of more than 100 million. In addition to being a dominant geographical feature of the region, the Sichuan Basin also constitutes a cultural sphere that is distinguished by its own unique customs, cuisine and dialects. It is famous for its rice cultivation and is often considered the breadbasket of China. In the 21st century its industrial base is expanding with growth in the high-tech, aerospace, and petroleum industries.

Geography

The Sichuan Basin is an expansive 229,500 km2 (88,600 mi2) lowland region in China that is surrounded by upland regions and mountains. Much of the basin is covered in hilly terrain. The basin covers the eastern third of Sichuan Province and the western half of Chongqing Municipality.

Editorial summary

Editorial reviewA practical starting point whose main value is the path it opens into stronger specialist and primary sources. The current 199-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. Its strongest next move is a source search built around Sichuan, Basin and basin.
Editorial analysis

Why this record matters

“Sichuan Basin” is worth following because a concise public description often conceals a longer documentary argument. Here, Sichuan, Basin and basin provides the most credible route into that argument.

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jul 2, 2026. The linked authority identifier is Q271294. Authority coordinates are 30.502, 105.502. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.

Critical limits

The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
