The area of moderately important ecological land is 69,615.45 hm, accounting for 21% of the total area. These areas are mainly located in the southern regions of study area, including the transition zone of moderately sensitive area, the main catchment areas of surface runoff and the secondary areas of ecological buffer zone along rivers or lakes (seeFig. 6). From the start of protecting natural ecosystems, ecological regulations in these regions include adjusting the structure and layout of
industrial, formatting the green industry with small environmental damage and high added value and building the ecological corridors and the eco-industrial development zone maintaining
ecological security
