白城市水足迹分析

The Analysis of Water Footprint in Baicheng City

水足迹是一种衡量用水的指标,不仅包括直接用水,也包括间接用水,可有效分析城市水资源利用与管理水平.文章运用CROPWAT 8.0以及白城市统计年鉴等,计算2016年白城市水足迹总量为95.44亿m³,其中农业水足迹为91.56亿m³、工业水足迹为0.61亿m³、生活水足迹为0.71亿m³、生态水足迹为2.56亿m³;农业水足迹占比高达95.93%;白城市水足迹效率为1363m³/万元,水资源利用效率较低.最后从发展特色生态农业、产业结构优化升级和宣传推广节水理念三方面提出白城市水资源可持续发展的建议.

Water footprint is a measure of water not only including water directly,also including indirect water.Water footprint can better analyze the utilization and management level of water resources.Baicheng City is a fragile ecological zone w让h dry climate in western Jilin.The shortage of water resources is extremely in Baicheng.This paper calculates the water footprint in 2016 in Baicheng by CROP WAT 8.0 and Baicheng City Statistical Yearbook・The total water footprint is 95.46 billion steres,the agricultural water footprint is 91.58 billion steres,the industrial water footprint is 0.61 million steres,the life water footprint is 0.71 million steres,and the ecological water footprint is 2.56 million steres.The proportion of agricultural water footprint is as high as 95.94 percent.The efficiency of water footprint is 1363 steres per Yuan in Baicheng and it is very low.Finally,the sustainable development of water resources in Baicheng is proposed from three aspects:the development of characteristic ecological agriculture,the optimization and upgrading of industrial structure,and the promotion of the concept of water saving.
