中文摘要 | 为探讨草地生态系统人工干预对区域经济福利的影响,揭示其间的内在规律,选取草地围栏、畜棚建设、草地灭鼠和人工草地建设作为草地生态系统人工干预的重要指标,以人均GDP、农牧民人均收入、人均肉产品产量作为反映区域经济福利指标,并以黄河源区为研究案例,利用回归分析法和SPSS软件建立人工干预和经济福利指标之间的相互关系。结果表明:以畜牧经济为主导的黄河源区,草地围栏、人工草地、畜棚建设与人均GDP、农牧民人均收入、居民人均肉产量均具有较高相关性,草地生态系统人工必要干预对经济福利具有重要的影响;且人工草地、畜棚、围栏单位面积变化对人均GDP、人均收入、人均肉产量具有较高的敏感性,其敏感性依此递减;灭鼠面积除对人均牛羊肉产量具有弱相关外,对人均GDP、农牧民人均收入也具有较高的相关性和敏感性。 |
英文摘要 | Manual positive intervention is the important means of maintenance dynamical equilibrium between grassland ecosystem structure and function.In order to discuss the effect of grassland ecosystem manual intervention on the regional economical welfare,and to release the linkage between grassland ecosystem manual intervention and economical welfare,pasture fence,livestock shed,pasture deratization,and artificial pasture construction were selected as the intervention indicators of grassland ecosystem,and GDP per capita,herdsman income of per capita,the output of meat per capita as the indicators of economic welfare.Authors analyzed the relationship between intervention indicators of grassland ecosystem and indicators of economic welfare based on regression and SPSS software in the source region of the Yellow River.The results show that there are close relationship between selected intervention indicators and economic welfare indicators.It means that these indicators of pasture fence,livestock shed,pasture,and artificial pasture area are of significant influence to GDP per capita,herdsman income per capita,output of meat per capita.And the sensitivity of economic welfare to the per unit area change of artificial pasture,livestock shed,and pasture fence ranks from high to low respectively.Except the indicator of pasture deratization has low relevance with output of meat per capita,the area of pasture deratization also has the high relevance with GDP per capita,herdsman income per capita. |
