RESUMO
The open-air burning of the massive generated crop straw in rural areas has been a troubling problem in China in recent decades, and the utilization and valorization of crop straw have provided promising solutions to it. However, due to the limitations in straw resources, economic, social, and technological conditions, different regions vary greatly with each other in the technological pathways and performance of straw utilization. By taking ten counties and districts of Xinyang City in Henan Province of China as examples, it analyzed the spatial distribution of straw yields and the adoption of five pathways of crop straw utilization in Xinyang City, and summarized three typical combination modes. In addition, it also provided the integrated model of FBWM-TOPSIS-PROMETHEE to evaluate the performance of crop straw utilization in the ten counties and districts, to provide local decision-makers with the pathways for promoting the utilization and valorization of crop straw. The results indicated that: (1) The endowment of straw resources and the straw utilization pathways in the ten counties and districts of Xinyang City vary greatly with each other; (2) Returning crop straw to the fields as fertilizer after being crushed is the mainstream mode of resource utilization of crop straw, although five technological modes have been adopted in Xinyang City; (3) Among the 10 counties, Huaibin and Xixian have the best performance of resource utilization of crop straw, and Shangcheng is the worst performer.
