Land use function transformation and associated eco-environmental effect in Fuzhou city based on"production-living-ecological space"
Based on the remote sensing monitoring data of the three phases of land use in 2000,2010 and 2020,according to the"production-living-ecological"land use dominant function classification,then through land use transfer matrix,eco-environmental quality index,ecological contribution rate of land use transition,this paper quantitatively analyzes the temporal and spatial evolution characteristics of structural transformation of"production-living-ecological space"and eco-environmental effect in Fuzhou city from 2000 to 2020.The results show that:(1)The distribution pattern of"production-living-ecological space"in Fuzhou is basically the same.The ecological space is the most widely distributed but showing a trend of shrinking,the living space is mainly distributed in the municipalities and is expanding.The production space is mainly distributed in the main urban area of Fuzhou and the eastern region,showing a trend of decreasing first and then increasing.(2)The conversion of"production-living-ecological space"is mainly based on the transfer-out of ecological space and the transfer-in of living space.The transfer-in amount and transfer-out amount are not balanced.The areas where the conversion is more active are mainly distributed in the main urban area of Fuzhou and the eastern region.Conversions in other regions are more sporadic.(3)The improvement and degeneration trend of eco-environmental quality coexist in Fuzhou,but the occurrence areas do not overlap in space.The overall eco-environmental quality index declines,and the spatial differentiation of eco-environmental quality is significant.The high-value area is mainly located in Yongtai County,and the low-value area is concentrated in the main urban area.The improvement of eco-environmental quality is mainly based on the conversion of agricultural production land and grassland ecological land to forest ecological land,while the conversion of forest ecological land and agricultural production land to industrial and mining production land is the main factor leading to the degeneration of eco-environmental quality.
