经济快速增长区建筑用地变化及其对生态质量的影响——以福建晋江为例
Built-up land change and its impact on ecological quality in a fast-growing economic zone :Jinjiang County, Fujian Province, China
摘要
Abstract
Since China's reform and opening-up,the rapid growth of China's economy has greatly accelerated the expansion of built-up land,which has affected regional ecological environment to a great extent.Taking Jinjiang County of Fujian Province,one of the fastest economic-developing counties in the coastal areas of southeastern China,as a case study area,this paper focused on analyzing the rapid built-up land expansion process of the county and its impact on county's ecological quality using remote sensing techniques.Based on two Landsat images of 1996 and 2015 of Jinjiang,the built-up land of the county was extracted using the index-based built-up index (IBI) and its change was analyzed.In the meantime,the ecological status of Jinjiang was evaluated with a recently-proposed remote sensing based ecological index (RSEI) and the relationship between the built-up land dynamics and the ecological status changes of the county was quantitatively examined.The results showed that during the period from 1996 to 2015,the area of built-up land of Jinjiang had a net increase of 68.54 km2,a growth of 45％,and the expansion intensity was 0.55.The expansion of the built-up lands has caused overall degradation of the county's ecological quality.The mean value of RSEI of the county had declined from 0.532 in 1996 to 0.460 in 2015,a drop of 13.5％.The area proportion of high ecological-quality grades also significantly fell from 39％ in 1996 to 21％ in 2015.The built-up land expansion intensity was negatively correlated with the ecological quality change.关键词
