Abstract:Forest ecosystems are important but fragile, and the rapid development of economy and society can affect the sustainable development of human beings. Therefore, the study of forest ecological security has a strong significance. Based on the date of forest panel from 1999 to 2014 in Hubei Province, this paper used the entropy method and fuzzy matter-element method to calculate the forest ecological security index, which was adjusted according to the ecological location coefficient obtained from the meteorological and terrain indices. Moreover,combined use of the ArcGIS software and the gravity analysis model in the present study revealed that:(1) the area with the highest ecological location coefficient was mainly distributed in the western and the central regions of Hubei Province. Futher,the area with the lowest ecological location coefficient was mainly distributed in the west,and the coefficient was correlated to a certain extent with economic development. (2)From the perspective of forest cover change in the 16-year study period, the counties with the worst forest ecological security grade increased 100%,reflecting that the overall situation of forest ecological security in Hubei is not optimistic. (3)The forest ecological security index of Danjiangkou and Songzi maintained an increasing trend during the study period. (4)The foest ecological security gravity center moved from the northwest to the southeast from 1999 to 2007,and thereafter from east to west at a high speed until 2014.
