Description
Many urban industrial concentration areas are becoming mixtures of intensive industrial and residential land use. While they play important roles in urban economy and employment, the energy consumption and pollution discharge in the process of industrial production bring mang negative effects on surrounding people and environments. In this paper, a tool is proposed to evaluate the environmental efficiency (EE) of the industrial concentration areas in order to coordinate the functioning of economic activities and environmental protection. Based upon discussion on the principal and significance of EE assessment in urban industrial concentration areas, an empirical study is conducted in Fengtai district, Beijing, to elaborate the idea from three aspects: socio-economic contribution, environmental load, and environmental risk. The study area was divided into 1379 grids of 500 m*500 m as the basic spatial unit while the spatial size effect and its rationality of the environmental functions have been testified. As the result, it turned out that the amount of the low EE grids account for 71.15% of the total districts while the rather high environmental load grids 20.18%. In the meantime, we found out that the area of low EE value grids have the tendency to aggregate towards the central urban areas, along urban express ring roads and around wholesale markets. These results shed light to implementing the refined environmental spatial management and control.
