An Adjusted Landscape Ecological Security of Cultivated Land Evaluation Method Based on the Interaction between Cultivated Land and Surrounding Land Types

Because the relationship between cultivated land and surrounding types is not taken into account, there existed a deviation in assessment of landscape ecological security. A novel methodology assessing security presented this study, grid scale adjusted index by disturbance environment index. This method was applied Xintai City, Shandong Province. The results demonstrate that (1) 1985 2015, constant loss 173.2 km2 land, bulk which converted to building primarily on outskirts cities. (2) has decreased; high-risk grids are located central metropolitan areas mining districts, have tendency spread out over time. (3) We three–dimensional model generate spatial combination zoning suggestions for regional use management. technique reduces errors may occur when relying solely features evaluation. evaluation’s more accurately reflect impact human activity urban growth, consistent with local features, higher quality reference value.
