Abstract
With the acceleration of regional urbanization and the improvement of economic development, the Central Plains Urban Agglomeration (CPUA) regional ecological environment problems become more and more serious. It is imperative to this regional sustainable development to clarify the ecological capital and spatial pattern and further analyze its driving factors. Based on the ecological economics method, this regional ecological capital value of 2000, 2005, 2010 and 2015 were evaluated by remote sensing model combined with Moderate Resolution Imaging Spectroradiometer (MODIS), normalize difference vegetation index (NDVI), and net primary production (NPP) data as well as other auxiliary data. Results showed that (1) ecological capital in this region was unevenly distributed, being mainly concentrated in the west and southwest (including Luoyang City and Pingdingshan City), and combined accounted for about 51.88% of the total ecological capital. Secondly, in the north-central section (including Zhengzhou City and Xinxiang City) aggregates accounted for about 21.02% of the total ecological capital. In Zhengzhou City, as the center, development of two lines consisted of a high value area to the southwest and northeast direction and a low value area to the northwest and southeast. (2) The regional ecological capital declined (-217 million yuan·a-1) from 2000 to 2015, but the ecological capital per unit area had no strong change. Central and western regions (including Zhengzhou, Jiaozuo, and Jiyuan) showed a strong downward move; whereas, the eastern region showed the opposite. (3) Under the influence of land use change, economy, and population, ecological capital of forest land, cultivated land, and grassland loss 4 662, 881 and 252 million yuan, respectively. Ecological capital per person fell by 13.4%. Zhengzhou City and Luoyang City, as the economic growth pole of the CPUA region, showed the fastest economic development and the most serious loss of ecological capital. Nevertheless, in the southwest and eastern regions, with slower development, regional ecological capital showed an inordinate upward movement. Overall, with rapid development of the regional economy, ecological environmental protection and governance were still important problems facing future development in the CPUA region; thus, this CPUA region should adhere to a green, environmental, low-carbon, intensive, and smarter development that promotes humanity and nature harmoniously.
