基于生态足迹理论，从省域、区域和市域3个不同的空间尺度对广东省2005年-2011年间水资源生态足迹和水资源生态承载力进行了计算与分析，结果表明：研究期内，广东省水资源生态足迹呈逐年减小的趋势，下降幅度为每年11.6%；万元GDP生态足迹逐年下降，水资源利用率逐年提高；全省水资源生态承载力较高，总体上呈现生态盈余，水资源利用状态为可持续。在区域差异上，粤北山区的水资源生态足迹最高，粤东地区最低；珠三角地区水资源生态压力最大，粤北地区最小。而市域空间分布上，韶关市、广州市人均水资源生态足迹在各地级市中较大，佛山市水资源生态压力位于各市之首。在社会经济发展过程中，各地区应根据区域水资源可持续利用状态，进行产业结构的调整，提高用水效率。
基于生態足跡理論，從省域、區域和市域3箇不同的空間呎度對廣東省2005年-2011年間水資源生態足跡和水資源生態承載力進行瞭計算與分析，結果錶明：研究期內，廣東省水資源生態足跡呈逐年減小的趨勢，下降幅度為每年11.6%；萬元GDP生態足跡逐年下降，水資源利用率逐年提高；全省水資源生態承載力較高，總體上呈現生態盈餘，水資源利用狀態為可持續。在區域差異上，粵北山區的水資源生態足跡最高，粵東地區最低；珠三角地區水資源生態壓力最大，粵北地區最小。而市域空間分佈上，韶關市、廣州市人均水資源生態足跡在各地級市中較大，彿山市水資源生態壓力位于各市之首。在社會經濟髮展過程中，各地區應根據區域水資源可持續利用狀態，進行產業結構的調整，提高用水效率。

Based on the theory of ecological footprint, t he ecological footprint and ecological carrying capacity of w ater resources in Guangdong Province were calculated and analyzed from 2005 to 2011 in aspect of the provincial, regional, and municipal scales. The results showed that ( 1) during the study period, the w ater resources ecological footprint per capit a of Guangdong Province decreases continuously with a rate of 11. 6%/a;( 2) t he water resources ecological footprint per 104 yuan GDP decrea-ses annually, indicating the increasing of ut ilization of w ater resources;and( 3) the w ater resources ecological carrying capacity is high in the provincial scale, which suggested the ecological surplus status and t hus the utilization of water resources is sustain-able. On the regional distribution, the ecological foot print w as highest in the northern mountain area of Guangdong w hereas low-est in eastern Guangdong. The water resources ecological pressure w as highest in the Pearl River Delta region whereas the low-est in northern Guangdong. On the municipal distribution, the water resources ecological footprint per capita was higher in Sha-oguan and Guangzhou than that in other cit ies, and the w ater ecological pressure in Foshan was the highest among al cities. In the process of socio-economic development, the industrial structure should be adjusted and the w ater use efficiency should be im-proved based on the status of sustainable utilization of water resources.
