生态学把生物与环境的关系归纳为物质流动及能量交换,景观社会同样如此。现实的情形是,只要抛开最近这数十年,在中国城市与乡村之间这种生态学意义上的物质流动一直运转良好,有效地保持了两者之间的能量、信息互换的平衡。到了后工业时代,单向流动的乡村失去了这种自我更新能力。现在随着革命性技术的演进,网络、物流、电子支付等等解决了资金、物资、信息流动的壁垒,再度出现了城乡对流的可能性,这让我们在此讨论乡镇更新就有了现实支撑。
Ecology, the relationship between biological and environmental induction of material flow and energy exchange, the same is true of landscape society. The reality is that as long as the recent decades have passed, this ecologically-meaningful material flow between urban and rural China has been working well and the balance of energy and information exchange between the two has been effectively maintained . In the post-industrial era, one-way villages lost this self-renewal ability. With the evolution of revolutionary technology nowadays, the barriers of capital, material and information flow have been solved by the network, logistics, electronic payment, etc., and the possibility of convection between urban and rural areas has once again emerged. This gives us a realistic support for the discussion of township renewal here .
