城郊县域生态经济协调状态与发展能力分析--以河北新乐市为例

以河北新乐市为例，运用生态足迹模型(Ecological Footprint)对当前生态经济协调发展的状态进行了定量评估．结果表明：(1)供需总量呈现出非均衡特点，生态赤字严重存在，目前的协调状态不容乐观；(2)供需结构呈明显不对称性，区外输入成为维持系统均衡发展的必要条件；(3)研究区具有较高的自然资源利用率。最后对该类地区产生生态赤字的原因和减小的可行性作了简要分析．并运用生态足迹计算结果和Ulanowicz的发展能力公式，测算了区域生态足迹多样性指数和发展能力．指出增加生态足迹多样性是提高发展能力的一条重要途径。

Analysis of the Coordination of Ecological Economy in Urban-Suburb District Based on Ecological Footprint Model

By taking an urban-suburb district,Xinle city,as an example,this paper applies the ecological footprint indicator to value the coordination state of the regional ecological economy.After research,we can draw a series of conclusions as follows:(1)The supply and need shows an uneven character,ecological deficit is serious,and the coordination state in Xinle city is not optimistic;(2)The structure of supply-need shows an obvious dissymmetry;(3)The natural re - sources usage of this city is higher than that of whole country and that of the eastern area.Fi - nally,the authors analyze the reasons of ecological deficit and the feasible measures to reduce it.On the base of above analyses,this paper uses the results of ecological footprint and the for - mula of development capability to calculate the diversity index and the development capability.Through the calculation,we can draw a conclusion that the diversity index of Xinle county is0.8996and the development capability of the ecological economy system is1.2918,and the re - search example have a higher development capability.The most important approach to improv - ing the development capability is increase the diversity of ecological footpring.
