    摘要:

    运用时空分析和相关分析等方法对广东省2000—2014年的水资源生态足迹进行评价,并在此过程中充分考虑了水污染的影响,以便准确地呈现广东省实际的水资源生态足迹及其影响因素。研究结果表明:2000—2014年广东水资源生态足迹呈上升趋势,城镇生活污水、人均GDP、工业废水是其增长的最主要因素;水资源生态足迹呈现出以珠三角为核心的中间高、四周低的半环状分布;全省的水资源为生态盈余,但东莞、佛山、广州、深圳、中山、汕头、珠海7市已多年出现水资源生态赤字;近年来全省对水资源利用率不断提高,其中粤北、粤东北地区最低。要实现广东省水资源的可持续发展则需要严格控制各城市(尤其是发达城市)的水污染生态足迹,从多个方面防治水污染。

    Abstract:

    This paper evaluates the water resources ecological footprint in Guangdong Province from 2000 to 2014 by using spatio-temporal analysis and correlation analysis, and fully considers the influence of water pollution in the process, and presents the actual footprint of water resources in Guangdong and the influencing factors. The results reveal that the ecological footprint of Guangdongs water resources showed an upward trend from 2000 to 2014, Urban sewage, GDP per capita and industrial wastewater were the most important factors for the growth. The ecological footprint of water resources shows a semi-circular distribution which take the Pearl River Delta as the core and low in four weeks. The water resources of the province are ecological surplus, but the 7 cities of Dongguan, Foshan, Guangzhou, Shenzhen, Zhongshan, Shantou and Zhuhai have been in the ecological deficit of water resources for many years. In recent years, the utilization of water resources in the province has been increasing, among which the north and the northeast of Guangdong are the lowest. To achieve sustainable development of water resources in Guangdong Province, we must strictly control the water pollution ecological footprint of all cities, especially developed cities, and prevent water pollution from many aspects.
