利用能值方法对省域内部各城市生态经济系统进行对比研究可以为区域可持续发展战略提供科学依据。应用奥德姆(H.T.Odum)创立的能值方法,定量分析宁夏五个地级市生态经济系统内的物流和能流,并对各城市的能值指标作对比分析。研究结果表明:宁夏各城市间的发展水平差距很大,主要是一种高资源消耗型经济发展模式。各市应在加强循环经济建设的同时,扩大开放程度,发展各自特色产业,形成互补机制,从而促进全区社会经济协调发展。
Using the method of emergy to comparatively study the eco-economic systems of cities in provincial areas can provide a scientific basis for the regional sustainable development strategies. Based on the emergy method established by H.T.Odum, this paper quantitatively analyzes the logistics and energy flow in the eco-economic system of five prefecture-level cities in Ningxia and makes a comparative analysis of the emergy index of each city. The results show that there is a wide gap between the development levels of cities in Ningxia, which is mainly a model of high resource consumption-oriented economy. Cities should, while strengthening the construction of a recycling economy, expand the degree of opening up and develop their own special industries so as to form a complementary mechanism so as to promote the coordinated development of the entire region.
