山东省农地利用可持续集约化的时空格局
Spatial-temporal pattern of sustainable intensification of agricultural land-use in Shandong Province, China
摘要
Abstract
Under the theoretical framework of sustainable intensification of agricultural land-use (SIALU),We used material flow analysis (MFA) method to establish evaluation index system for SIALU by utilizing data in 2000,2005,2010 and 2015 to quantify the level of SIALU of 17 cities in Shandong Province,and analyzed the variation in input-output of resources factors of agricultural land,spatial distribution of resource productivity and environmental economic efficiency,in order to reveal spatial-temporal differentiation of SIALU.Results showed that the direct material input to agricultural lands decreased,whereas hidden flow,stock and pollutant emissions increased gradually from 2000 to 2015.The material productivity of all cities in the province showed that the coastal areas in the peninsula were relatively lower than the southern region,and the level of material productivity in the northwest region was relatively higher.Environmental economic efficiency was gradually enhanced,and the western region was relatively higher than coastal area of the peninsula.During the period examined here,the spatial pattern of SIALU of various cities showed clustered distribution change,with the western region tending to gradually increase and the eastern region tending to gradually reduce.The dynamics of SIALU among different regions were divided into six grades:Northwestern Shandong ＞ Northern Shandong ＞ Southwestern Shandong ＞ Southern Shandong ＞ Central Shandong ＞ Coastal areas of Shandong Peninsula.关键词
