Full utilization potential in rocky desertification arearea of southwest China-Take Guizhou province as a case

This paper takes Guizhou province, which has a serious problem of karst rocky desertification, as the research object. From the perspective of the full quantitative utilization of straw resources, this paper estimated the potential of the resource of major crops and the per capita amount of straw in this province, and clarified the regional characteristics of the straw resources in Guizhou Province. Combined with the calculation of the competitive demand for straw utilization in Guizhou Province and the analysis of the full quantitative utilization potential of straw in the whole province and nine cities and prefectures, the difference of the amount of straw resources in karst counties and non-karst counties in Guizhou Province was revealed, and the correlation between the amount of straw resources and the grade of rocky desertification was also revealed. The results showed that Guizhou Province was rich in straw resources in 2017, and the amount of straw resources that could be collected in karst counties was higher than that in non-karst counties. The level of rocky desertification is positively correlated with the amount of resources collected per capita. © 2022, Solar Energy Periodical Office Co., Ltd. All right reserved.
