摘要
为了分析宁夏回族自治区地区生产总值和农牧林鱼业受水土流失影响的关联程度,本文采用灰色关联分析法,分别计算出水土流失面积与地区生产总值和农牧林渔业的灰色关联系数和灰色关联度.通过计算和分析发现,同一组合中地区生产总值和农林牧渔业生产总值是有差异的,在不同组合中地区生产总值和农林牧渔业生产总值也存在着差异.关联度从大到小的排列顺序为牧业＞林业＞农业＞农林牧渔业总产值指数＞地区生产总值.其中牧业和水土流失面积的关联度最大,为0.768 6,说明在宁夏回族自治区中牧业的生产和发展受到水土流失面积的影响最为严重.本文反映了研究地区生产总值和农牧林鱼业受水土流失影响的关联程度,为后续研究提供了研究参考.
Abstract
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.
