摘 要:随着社会经济的不断發展,石家庄城市化进程快速推进,导致城市地表径流发生了一系列的变化。本文以石家庄为例,深入分析城市化对城市蒸散发的影响。其间对石家庄相应年份卫星图进行加工,以地物类型面积的变化情况反映石家庄的城市化发展趋势;选取石家庄不同气象站及周边有代表性气象站点的蒸发数据,分析城市化对蒸散发的时空影响;通过石家庄与周边郊县(区)藁城、正定、栾城、井陉的蒸发量进行对比,分析石家庄城市化进程对蒸发量的影响,进而明确石家庄的城市化方向。

Abstract: With the continuous development of society and economy, the rapid progress of Shijiazhuang's urbanization has led to a series of changes in urban surface runoff. This paper took Shijiazhuang as an example to deeply analyze the impact of urbanization on urban evapotranspiration. During the process, the satellite images of Shijiazhuang in the corresponding years were processed, and the changes in the area of the features were used to reflect the development trend of Shijiazhuang's urbanization; the evaporation data of different weather stations in Shijiazhuang and surrounding representative weather stations were selected to analyze the time and space of urbanization on evapotranspiration influences; by comparing the evaporation of Shijiazhuang with the surrounding suburban counties (districts) Gaocheng, Zhengding, Luancheng, and Jingxing, the impact of the urbanization process of Shijiazhuang on the evaporation was analyzed to clarify the direction of Shijiazhuang's urbanization.

2000年以来,石家庄的城市化已经进入飞速发展的新时期。经济发展日新月异,社会建设日益活跃。石家庄环渤海湾经济区,历史文化源远流长,交通顺便,经济发达,具有巨大的经济发展潜能[1]。在此背景下,本文就石家庄城市化土地利用变化对蒸散发的影响这一问题,从时间和空间进行系统研究,旨在揭示石家庄城市化对市区蒸散发量的影响。
1 研究现状
1.1 国内外研究的现状
近年来,我国城市化进程迅速推进,耕地面积却出现一定下降,不利于社会持续发展。国内外学者已经做了许多研究工作,并且取得了大量的研究结果。
Ermesto[2]等进行了一项针对墨西哥城蒸发数据的研究,发现其城市雨岛效应的频率有所增加,蒸发量也持续增加。……
