【摘要】：运用生态足迹方法对水资源进行流量资本和存量资本区分,测算分析了中国31个省市1997—2014年的水生态足迹广度与深度。结果显示:(1)中国的水生态足迹广度受年际水资源量丰枯影响,总体呈波动趋势;各省市的水生态足迹广度存在着明显差异,南方地区水生态足迹广度普遍大于北方地区;(2)研究期内,中国的水生态足迹深度只有1998年为1,其余年份的水资源流量资本已不能满足人类生产生活的需求,需要消耗水资源存量资本;各省市之间水生态足迹深度相差较大,整体上北方高南方低,其中14个省份18年的平均水生态足迹深度为1,平均水生态足迹深度最高的地区是宁夏的308.12;(3)运用空间自相关方法对31个省市的水生态足迹广度和深度进行分析得出,中国省际水生态足迹广度与深度均存在明显的空间集聚现象。水生态足迹广度H-H集聚地区主要集中在中国南方地区,水生态足迹深度H-H集聚地区主要集中在中国北方地区。通过对全国水生态足迹广度与深度的测度分析为水生态足迹分析提供新的研究方法,同时也为区域水资源可持续利用提供理论依据。
[Abstract]:The ecological footprint method is used to distinguish the discharge capital and stock capital of water resources, and the breadth and depth of water ecological footprint of 31 provinces and cities in China from 1997 to 2014 are calculated and analyzed.The results show that the breadth of water ecological footprint of China is affected by the annual water resources volume, and the water ecological footprint of different provinces and cities has obvious differences.During the period of study, the depth of water ecological footprint in China was only 1 in 1998, and the capital of water resources discharge in the other years could not meet the needs of human production and life.Need to consume water resources stock capital; the depth of water ecological footprint varies greatly between provinces and cities, the whole north is high and the south is low,The average depth of water ecological footprint in 14 provinces is 1 in 18 years. The highest depth of water ecological footprint in Ningxia is 308.12 in Ningxia. The spatial autocorrelation method is used to analyze the breadth and depth of water ecological footprint in 31 provinces and cities.There are obvious spatial agglomeration phenomena in the breadth and depth of the ecological footprint of interprovincial water in China.The water ecological footprint breadth H-H concentration area is mainly concentrated in southern China, and the water ecological footprint depth H-H accumulation area is mainly concentrated in northern China.The measurement and analysis of the breadth and depth of water ecological footprint in China provide a new research method for the analysis of water ecological footprint, and also provide a theoretical basis for the sustainable utilization of regional water resources.
