黄河流域山东段土地利用变化对生态系统服务价值的影响
The impact of land use change on the value of ecosystem services in the Shandong section of the Yellow River basin
摘要
Abstract
Based on the landuse data of 1980,2000,and 2018,with the support of geographic information system technology,we compared the land use changes in the Shandong section of the Yellow River basin from 1980 to 2018,estimated the value of ecosystem services and analyzed the impact of land use changes on the ecosystem service value.The results showed that:(1)There was a significant difference between the changes of various types of land use in the study area,the area of unused land,woodland and arable land decreased,while the area of construction land and water increased.(2)The ecosystem service value of the study area showed a downward trend and then an upward trend,with a total increase of 5.22×107 yuan.The service function value of the two indicators of climate regulation,soil formation and land protection was decreased the most significantly,and the service function value of the two indicators of water conservation and waste treatment was increased the most.(3)11 counties had a marked decline in the per unit area ecosystem service value,with Kenli District as the most prominent one;34 counties had a marked increase in the per unit area ecosystem service value,with Wucheng County as the most prominent one.(4)The sensitivity index of the same land use type did not exceed 1 during the study period,and its accounting results were credible.关键词
