面向SDGs的塔里木河流域农业灰水足迹分析

Abstract: The dry Tarim River Basin in Northwest China acts as a crucial ecotone for Xinjiang’s agricultural andgrazing resources. Therefore, studying agricultural nonpoint source pollution is essential for the green andsustainable growth of basin agriculture. This research offers a gray water footprint theory-based assessment indexfor China’s sustainable development. Furthermore, the Tarim River Basin’s regional and temporal variationpatterns are examined using SDGs framework. The agricultural gray water footprint’s intensity and efficienciesare estimated for 2006-2020. The findings are shown as below. (1) The Tarim River Basin’s entire agriculturalgray water footprint has reduced, falling from 6.95 × 1010 m3 in 2006 (highest value) to 3.96 × 1010 m3 in 2017(lowest value). The main source of the gray water footprint is animal husbandry. (2) In the Tarim River Basin, theintensity of the agricultural gray water footprint has decreased by 62.5% from 4.48×104 m3·hm-2 in 2006 to 1.68×104 m3·hm-2 in 2017. (3) The Tarim River Basin’s agricultural gray water footprint efficiency has increased from0.6 yuan·m-3 in 2006 to 4.03 yuan·m-3 in 2019. To sum up, initiatives to improve the water environment in theTarim River Basin should emphasize encouraging the integrated development of agriculture and animalhusbandry in agricultural areas, modifying the livestock and poultry breeding structure and putting livestock andpoultry manure recycling into practice.
