Changes of peanut distribution from 2001 to 2020 in Shandong Province and the analysis of indicators for these changes
To support the decision making for peanut production sustainability,based on the statistical data from 2001 to 2020,we use mathematical statistical approach and spatial exploring method to analyze the changes of peanut distribution and clarify the influence indicators for the changes.The results showed that during this two de-cades,the peanut harvested area and production decreased by 33.00%and 22.34%,respectively,while the yield in-creased by 15.93%.The spatial patterns of peanut concentrated to the northwest,including Linyi and east region,such as Yantai,Weihai and Qingdao.There are four years that the contribution for peanut production of harvested area is higher than that of yield,and 16 years on contrast.Through the spatial exploring method,the cropland de-creased and the proportion of harvested area of the economic crops decreased,and the proportion of peanut produc-tion declined consequently.The net profits of peanut production in Shandong were lower than that in other regions and dropped in recent years,and then the harvested area and production declined regularly.In addition,the demo-cratic and global market of peanut and its processed products was not stable,restricting the development of the pea-nut industry.
