Characteristics of Spatial and Temporal Distribution of Cash Crop Straw Resources in Anhui Province
Based on the planting area and production data of cash crops in Anhui Province from 2014 to 2023,the straw resources were estimated by using the grass-valley ratio method,and its e-volution trend over time was analyzed.In order to clearly present the spatial distribution characte-ristics of cash crop straw and the grading of yields,ArcGis software was used to optimize the clas-sification method together with the nine-grid matrix diagram for graphical presentation.The results of the study show that:from 2014 to 2023,the sown area of cash crops in Anhui Province showed a first decline and then increase momentum,while the straw production was briefly rising and then declining and then slowly rebounded;the spatial distribution of cash crop straw resources was characterized by"high in the north and low in the south",which mainly concentrated in Anqing,Hefei,Bengbu and Fuyang.The spatial distribution of cash crop straw resources is characterized by"high in the north and low in the south",mainly concentrated in Anqing,Hefei,Bengbu and Fu-yang;the highest yield area and per capita yield are found in Bengbu and Anqing,respectively.
