西北“水三线”生态经济体系与调控模式研究 postprint

Abstract: In the contexts of the national strategies for ecological protection and high-quality development in theYellow River Basin, as well as of the new era of development in western China, it is necessary to alter the ecological conditions and resource endowment of the“three water-related lines”area in northwest China (an area occupying two distinct basins of the Yellow River and the inland rivers) and to innovate a framework and paradigmsfor coordinated ecological-economic development specific to the area. Based on existing ecological-economicstheories, as well as on the developing philosophy of“a benign environment equal to wealth”and the concept ofthe“human-nature community”, we propose a conceptual ecological-economic framework for the“three waterrelated lines”area, in which we identify the interactions between subsystems and their mechanisms and suggestfour paradigms and four eco-economic hub areas. Further, we propose a layout for modern agriculture and indicate the pathway to coordinated urban and rural development in the four suggested eco-economic hub areas. Weconclude that the proposed“three water-related lines”ecological-economic framework represents a theoreticalfoundation on which to base decisions concerning the layout of socio-economic development and ecological-environmental protection, the construction of ecological-economic hubs, and the overall harmonious ecological-economic development of northwest China.
