摘要： Crop straw is a valuable renewable resource, which holds great potential to be developed further. The estimation of the yield and collectable amount of crop straw is a foundation for its comprehensive utilization. Based on the output of major farm products, the collectable amounts of different kinds of crop straw in China and their distribution were estimated in this study. China holds enormous crop straw resources, and more than 60986.1x10(4) t of straw resources could be collected in 2014. Corn stalk, rice straw and wheat straw were the three most abundant crop straws, whose collectable amounts in 2013 reached 21481.0x10(4), 15420.1x10(4) and 11519.4x10(4) t, accounting for 35.2%, 25.3% and 18.9% of the total collectable crop straw, respectively. Henan, Heilongjiang and Shandong were the richest provinces in straw resources, where the collectable amounts of the three crop straws reached 6142.1x10(4), 5901.0x10(4) and 4894.5x10(4) t, accounting for 10.6%, 10.2% and 8.4% of total collectable amount of those in China, respectively.
