基于水资源生态足迹的南京市水资源分析,以南京市的水资源数据为依据,计算南京市2005-2015年的水资源生态足迹和水资源生态承载力,分析南京市的水资源状况

摘要:水资源生态足迹模型理论已经被我国的众多学者所肯定并加以运用,本文采用水资源生态足迹模型,以南京市的水资源数据为依据,计算南京市2005-2015年的水资源生态足迹和水资源生态承载力,分析南京市的水资源状况。结果表明,2005-2015年,南京市多年平均水资源人均生态足迹为9。98hm2/人,总体呈下降趋势,多年平均人均生态承载力为2。15hm2/人,人均生态足迹是人均生态承载力的4。64倍。2005-2015年南京市水资源虽呈现出波动较大的生态赤字现象,但其生态赤字数据走势基本与水资源生态足迹走势一致,呈下降趋势,说明生态足迹与生态承载力的差值在不断缩小,水资源生态承载力不断上升。这与近年来南京市开展的各项水资源保护管理措施正常有序的实施有关。说明南京市的经济发展与水资源保护正不断向着稳定趋势发展,政府的水资源保护措施不断发挥效力,人民的节水、生态观念在不断提高。91184

Abstract:The ecological footprint model of water resources has been affirmed and applied by many scholars in China。 Based on the data of water resources in Nanjing, the ecological footprint of water resources in Nanjing from 2005 to 2015 is calculated。 Analyze the sustainable development of water resources in Nanjing。 The results showed that the average ecological footprint of water resources per capita in Nanjing was 9。98hm2 / cap from 2005 to 2015, and the average ecological carrying capacity per capita was 2。15 hm2 / cap, and the average ecological footprint per capita was 4。64 times of the ecological carrying capacity per capita。 The ecological deficit of water resources is basically the same as the trend of ecological footprint, and the difference between ecological carrying capacity and ecological footprint is shrinking, and the ecological carrying capacity of water resources is rising constantly。 This is related to the normal and orderly implementation of various water resources protection and management measures carried out in recent years in Nanjing。 This shows that Nanjing's economic development and water resources protection work is constantly tending to  balance  development。  The government's water protection measures are constantly playing its part。 People's water-saving and ecological ideas are constantly improving。

Keywords:water resources, Nanjing, ecological footprint, ecological carrying capacity, sustainable utilization,
