長江中游城市群承東啟西、連南接北,是長江經濟帶的重要組成部分。作為地區經濟發展新的增長極,在長江經濟帶堅持生態優先、綠色發展的戰略定位下,長江中游城市群更應該重視地區生態文明建設與資源環境保護,特別是水資源的可持續利用與保護。基于此,本文將長江中游城市群整體作為研究對象,利用水足跡理論與方法,通過計算該地區2000—2015年水足跡的構成,定量分析長江中游城市群近16年來水資源利用狀況,并結合協調發展脫鉤評價模型對水資源利用與經濟增長協調關系進行評價。結果表明:(1)長江中游城市群近16年來水足跡呈現先小幅波動上漲、再穩步上漲的總體上漲趨勢,農業生產用水是水足跡的主要組成部分;(2)水資源利用效率逐年提高,但水資源利用結構不合理,農業生產用水所占比重過大,水資源基本用于本地區內部經濟發展,對外交流不足;(3)水資源總量豐富,但水資源利用與經濟增長基本處于相對脫鉤的初級協調狀態。基于以上研究結果,本文從"嚴管理、抓節水、調結構、促發展"四個方面提出了促進長江中游城市群水資源利用與經濟協調發展的政策建議:積極落實嚴格的水資源管理制度,從源頭上杜絕水資源浪費現象;重點抓好農業節水工程建設,大力推動生產生活節水;提高對外經濟貿易水平,調整水資源利用與農業產品消費結構;大力促進產業協同發展,加快經濟增長與水資源利用向優質協調發展狀態轉變。

Connecting the east and west,the urban agglomeration in the middle reaches of the Yangtze River is an important component of the Yangtze River Economic Belt.As a new growth pole for regional economic development,the urban agglomeration in the middle reaches of the Yangtze River should pay more attention to ecological civilization construction and resource environment protection especially to the sustainable utilization of water resources and protection under the strategic positioning of ecological priority and green development in the Yangtze River Economic Belt.Based on this,making the urban agglomeration in the middle reaches of the Yangtze River as the research object on the whole,the paper used the water footprint theory and method to analyze water resources utilization of the middle reaches of the Yangtze River in nearly 16 years by calculating the composition of the region in 2000 to 2015 and evaluated the coordinated relationship between water resources utilization and the economic growth in the urban agglomeration in the middle reaches of the Yangtze River by using the decoupling evaluation model of coordinated development.The results shows:(1) In nearly 16 years,the water footprint increased with small-scope fluctuations firstly,and rose steadily in the end which had a ascend trend on the whole.Agricultural production consumption was the main component of the water footprint.(2) Although the utilization efficiency of water resources increased year by year,the structure of the water resources utilization was not reasonable and the proportion of water consumption for agricultural production was too large.Water resources were mainly used for internal economic development in this region,lack of external exchanges.(3) Although the total water resources are abundant,the relationship between water resources utilization and the economic growth was in a relative decoupling state of primary coordination.Based on the above research results,we put forward policy suggestions that from the aspects of strict management,emphasis on water saving,structural adjustment and promoting the development,we can promote the coordinated development between water resources utilization and economic growth in the urban agglomeration in the middle reaches of the Yangtze River.First,implement the strict water management system to avoid water waste from the origin.Second,focus on the construction of agricultural water-saving project and promote watersaving in production and daily life.Third,improve the level of foreign economic trade and adjust the structure of water resource utilization and agricultural product consumption.In the end,promote the coordinated development of industry and establish the coordinated relationship between water resources utilization and the economic growth.
