Effect of Compactness of Urban Growth on Regional Landscape Ecological Security

With rapid urbanization destroying the ecological environment, scholars have focused on ways to coordinate harmonious development using urban spatial layouts and landscape security. To explore security (the elements, positions connections that are of key significance health safety processes) from perspective form evolution pattern will help open a new management research, become basic work space policy implementation beautiful China strategy. Based growth land use data 356 cities in China, this study applied geographically weighted regression (GWR) model quantify impact China’s at level. The research results show that: (1) some extent, infilling has certain effect enhancement regional security; (2) In three control variables (DEM, Population density GDP), following conclusions drawn: planning should reasonably allocate resources according local topographic features obtain higher increase population leads fragmentation diversity regions, which makes weak; more economically developed areas stronger This paper highlights importance patterns addition, considering different trajectories developing countries, proposes targeted recommendations, providing reference for managers formulate reasonable policies realize sustainable with goal control.
