Suibin County lies in the Sanjiang Plain, where the Heilongjiang and Songhua rivers cross a low, flat landscape. A 2026 county forestry page says the area contains 28 rivers, many lakes and river islands. Along the Songhua, the wetland corridor extends for 142 kilometres and includes 43 islands; the county’s Amur boundary runs for 83.6 kilometres. These numbers describe a water network rather than one single marsh. The low ground, channels and islands create a mosaic whose shape follows the two rivers and their floodplain, making wetlands a defining part of the county’s geography.

Suibin’s Wetlands: A Protected Network of Rivers and Lakes
In Suibin, the Amur and Songhua run through a protected landscape of wetlands, river islands and shallow lakes. The county’s reserve and Crescent Lake wetland park show two scales of conservation.

A reserve measured in many habitats
The Heilongjiang provincial government established the Suibin Liangjiang Wetland Nature Reserve in 2007. The county describes its 56,962 hectares as including water, islands, shrubland, forest and marsh along both rivers. That mix helps explain why the reserve is not a single open-water feature. Shrub-covered islands and marshy lowlands form part of the same protected landscape as the river margins. The reserve’s location along an international boundary also gives the wetlands a role beyond habitat: the county notes their importance to land protection and international environmental commitments. The 2007 reserve designation brought these separate habitats into a single conservation framework, preserving a large landscape rather than a single signature viewpoint.
Crescent Lake is a separate wetland park
Crescent Lake became a national wetland park in 2015. Its 570-hectare area follows a narrow east–west strip centred on the lake and the Qujialiangzi River, a tributary of the Amur. The county page gives its boundaries by nearby roads and villages, while the larger Liangjiang reserve covers a much broader landscape. The park’s shape shows how a protected site can follow a particular lake-and-stream system while remaining adjacent to a wider reserve. Together, the two designations show Suibin’s water geography managed at different scales: a county-sized protected network and a defined wetland park visitors can locate on a local map.
