城市礦產是工業化和城市化過程的產物,是一種載能性、循環性、戰略性資源,引起了各國政府和學者的高度關注,但目前國內外針對城市礦產的研究還未形成完整的理論體系和研究方法。本文指出,城市礦產是指蘊藏于城市中具有較高經濟價值并可回收利用的二次資源,是相對于蘊藏于地下的原生礦產的另一種重要資源,在蓄積、回收和處理等方面都具有鮮明的特征。結合生命周期分析和物質流分析方法,認清城市礦產形成的過程和規律,揭示城市礦產成礦機理,是城市礦產研究的理論基礎;立足于滿足戰略性新興產業發展的需要,以"資源-技術-環境"為主軸,構建城市礦產戰略性篩選體系,對城市礦產進行動態篩選并進行國際比較,把握城市礦產開發重點和時序,是城市礦產有序開發利用的前提條件;以城市礦產流量與存量關系刻畫為主線,對重點城市礦產進行分類評估,測算其開發潛力,分析其時空格局歷史演變模式,預測未來發展趨勢,繪制城市礦產潛力時空圖譜,是城市礦產研究的重點;以城市礦產與原生礦產、海外礦產的關系為主線,結合系統動力學研究城市礦產開發利用的資源效應、環境效應和文化效應,把握城市礦產開發利用的綜合影響,是城市礦產研究的關鍵;以城市礦產全生命周期管理為主線,研究城市礦產政策演變、對政策效果進行評價,充分發揮市場、政府、社區的作用,并結合移動互聯網時代特征進行管理和政策設計,是城市礦產研究的落腳點。基于現有的研究基礎和實際需求,未來應進一步加強城市礦產大數據、都市圈城市礦產開發、中小城鎮城市礦產開發、互聯網+城市礦產回收等領域的研究。

Urban mineral with energy-carrying,circular and strategic is an inevitable product of industrialization and urbanization,which has attracted attention from governments and scholars all over the word. But till now,the study on urban minerals is weak in China and abroad,and there is still not yet a complete theoretical system and sophisticated research methods. In this paper,urban mineral is redefined based on current research. Urban mineral is a crucial resource as well as primary ore,and it could be comparably economic valuable and recyclable secondary resources from the city,with particular features on accumulation,recovery and disposition.The main research contents and methods of urban minerals include the followings. First,it is the research base to reveal mineralization mechanism of urban minerals based on analyzing the forming process and regularity using life cycle analysis and substance flow analysis.Second,constructing a strategic screening system of ‘resource-technology-environment’,and making dynamic screening along with international comparison,to confirm the developing priorities and sequences is the preconditions of developing urban minerals. Third,it is vital to classify and measure different kind of urban minerals,and evaluate the development potentials based on the relationship of flow and stock,and then analyze the historical evolution model and predict the future developing trend,and realize a spatial temporal map of urban minerals potentials. Forth,it is necessary to assess the comprehensive impacts of urban mining,such as resources impacts,environmental impacts and sustainable consumption cultural impacts,according to the coupling relationship of urban minerals,virgin ores and overseas minerals. Last but not least,it is our target to design management system and policies of urban minerals under the context of mobile Internet era,based on studying policy evolution,assessing policy impacts in line with the whole life cycle of urban minerals. Based on these findings and the social demands,future urban minerals study should focus mainly on the following four areas:(1)the big data research on urban minerals;(2)the research on urban minerals in metropolis circles;(3)the study on urban minerals in medium and small towns;(4)research on Internet plus recycling of urban minerals.
