Assessment on the Natural Suitability for Human Settlements in Farming-pastoral Ecotone of Cities
摘要
Abstract
Based on the GIS technology and remote sensing image, through the establishment of vector grid operation on four factors as RDLS, CI, WRI and LCI, it is difficult to find the grid sample act as the absolute best natural living appropriate character. Using the coefficient of variation as weight to evaluate the comprehensive natural living appropriate index, the results showed that the index values in the southern six counties were higher than the northern six ones, and that was contrary with the economic development level and the population flow trend. It was thought that if the number of population exceeds the bearing capacity of ecological environment seriously on temporary during the mining period, it can be made up for by strengthening the ecological construction investment through economic levers. But if the density of population keeps on a high level for a long time, it would cause a serious destruction on the local ecological environment and is hard to recover.关键词
