Study on the grey correlation between soil erosion and the development of agriculture,forestry,animal husbandry,and fishery in Ningxia Hui Autonomous Region
In order to analyze the correlation between the Gross Domestic Product(GDP)and the agriculture,forestry,animal husbandry,and fishery industries,and soil erosion in Ningxia Hui Autonomous Region,this study employs the Grey Relational Analysis method.The Grey Relational Coefficients and Grey Relational Degrees between soil erosion area and GDP as well as the agriculture,forestry,animal husbandry,and fishery industries are calculated separately.Through calculation and analysis,it is found that within the same combination,there are differences between the GDP and the total output value of agriculture,forestry,animal husbandry,and fishery industries.Moreover,differences exist among different combinations.The sequence of correlation degrees from highest to lowest is as follows:animal husbandry＞forestry＞agriculture＞total output value index of agriculture,forestry,animal husbandry,and fishery industries＞GDP.Notably,animal husbandry ex-hibits the highest correlation degree with soil erosion area at 0.768 6,indicating that in the Ningxia Hui Autonomous Region,the production and development of animal husbandry are most severely affected by soil erosion.This study reflects the correla-tion degree between GDP and the agriculture,forestry,animal husbandry,and fishery industries affected by soil erosion,pro-viding a research reference for subsequent studies.
