Analysis of Harmonious Development of Eco‐Economic System in the Second Green Isolation Area in Beijing

Abstract

The construction of green isolation areas is an important means to prevent the sprawl of central urban areas, guide the rational layout of urban green spaces, and protect the ecological environment. However, with the continuous construction advancement of green isolation areas in Beijing, the problems of mutual restriction between ecology and economy are increasingly prominent, but few studies are devoted to such problems. Taking the second green isolation area of Beijing in 2000, 2010, and 2020 as the research objects, the kilometer grids were taken as the basic research units, and the land cover data and GDP data were placed in the unified spatial coordinate system by GIS software; also, the equivalent factor method was adopted to calculate the ecological service value (ESV) of the research region, and the eco-economic harmony degree (EEH) was calculated using the ratio of ESPpr to GDPpr. This research innovatively used the kilometer grid as the basic research unit to study the second green isolation area in Beijing and compared the harmony degree between the second green isolation area and the overall ecological, economic system of Beijing, so as to dynamically compare the ecological environment changes in the second green isolation area during the study period and the degree of mutual influence in the process of economic development. The study found that the construction of the second green isolation area improved the harmony of the eco-economic system in a certain area, but it failed to effectively curb the spread of construction land in the urban area of Beijing. The research results can provide scientific guidance for the coordinated planning of the ecological economy in the second green isolation area.

Evaluating the Spatial Evolution of the Eco-Economy Harmony in Anxi County, China, Based on Ecosystem Services Value

“…A widely used estimation method is to calculate the rate of change in ESV per unit area and the rate of change in GDP per unit area throughout the study period. This method enables the effective quantification of the coordinated relationship between economic development and ecological changes, enabling a more dynamic comparison of the degree of interaction between ecological changes and economic development throughout the study period [45].…”

“…Since EEH manifests itself as the evolution of ecological environment and economic development over the study's time period [45], this study segregated the period into three segments, 1999-2009, 2009-2019, and 1999-2019, to evaluate the EEH. Based on Equation (8), the EEH values for each time period in Anxi County were calculated as shown in Table 8.…”
