摘要
利用世界粮农组织和世界银行统计的人均水资源、跨境水资源以及水资源利用等数据,借助ArcGIS制图与图表分析法,对近年来"一带一路"沿线国家水资源及开发利用状况进行分析,结果表明:人均可更新水资源量最高的地区为东南亚,最低的地区为西亚北非,具有明显的地域差异性;人均可更新水资源量缩减最为突出的为西亚地区,而中东欧及部分国家略有增长趋势。水资源开发利用以东南亚和西亚地区对比最为明显,西亚水资源利用率最高,东南亚最低。多数国家存在跨境水,中东欧地区跨境水比例较高,部分国家可更新水资源中入境水成分为零。亚洲地区农业用水比例普遍较高,而中东欧地区工业用水和城市生活用水比例较大。
Using ArcGIS mapping and a chart analysis method to analyze data on per capita water resources,cross-border water resources,and water resource utilization from the Food and Agriculture Organization of the United Nations and the World Bank,the development and utilization status of water resources in countries targeted by the Belt and Road initiative in recent years were investigated.The results show that the area with the highest amount of water resources per capita is Southeast Asia,while the areas with the lowest are West Asia and North Africa,with obvious regional differences.In most countries,the amount of water resources per capita is shrinking,most prominently in West Asia;meanwhile,in Central and Eastern Europe,there is a slight growth trend.The development and utilization of water resources is clearest in Southeast Asia and West Asia.The rate of utilization of water resources is highest in West Asia and lowest in Southeast Asia.Cross-border water exists in most countries,although the proportion of cross-border water in Central and Eastern Europe is higher than that elsewhere.In some countries,the amount of imported water resources is zero.The proportion of water used for agriculture is generally higher in Asia,while the proportion of water used in industrial and urban domestic settings is greater in Central and Eastern Europe.
