【摘要】 以汕头市6区1县为研究区域,以2003年区域变更调整数据和2007年现状土地利用数据作为数据源,通过对能反映各区县生态环境转变的主要土地利用类型的变化情况进行研究,说明汕头市土地利用变化对生态环境质量的影响。结果表明,汕头市的耕地面积持续降低,建设用地扩张速度过快,尤其是居民点及工矿用地。汕头市土地利用变化使得全市整体生态环境质量有改善的趋势,但同时也存在个别区县生态环境质量略有下降的现象。更多还原

【Abstract】 With six districts and one county in Shantou City as study area,taking 2003 and 2007 remote sensing image as data source,the data of land use type was extracted from it. The speed and level variation of land use types were analyzed. At the same time,the quality of the ecological environment and the dynamic changes were evaluated. The results showed that the cultivated area continued to decline,then the expansion speed of construction is too fast,especially the residential and industrial areas. Due to the importance of the ecological environment,Shantou City’s eco-environment quality was improved obviously. However,eco-environment quality was also declined in some region.更多还原
