What is the tree count in Zhongwei?
Zhongwei has an estimated 60,330 trees across the 12.51 km² of land measured — 19.3% tree cover, 11 percentage points short of the 30% tree-cover target set for this area.
How many more trees does Zhongwei need?
Zhongwei needs roughly 33,447 more trees to close a 11-point shortfall against its 30% tree-cover target — about 735.8 t of extra CO₂ absorbed per year once grown.
How are Zhongwei's air quality and tree cover measured?
Air quality comes from ground monitoring stations via OpenAQ where one reports nearby, and otherwise, as here, from the Open-Meteo / CAMS model, which may differ from street-level monitors. Tree cover is measured from Sentinel-2 L2A (ESA Copernicus) via Earth Search satellite imagery at 10 m detail across a 2 km radius around Shapotou District; the tree count is an estimate derived from that cover.
