- Abstract:
-
The index system of land ecological security of Hengyang City was constructed based on the 19 indicators that can reflect the characteristics of land use in red soil hilly region in south Hunan, such as soil erosion rate, management rate of degradation land and the percentage of sloping land>25°, etc. The land ecological security of Hengyang City from 2006 to 2010 was also evaluated by using the entropy method and index additive model. The result indicated that land ecological security index went upward in Hengyang City from 2006 to 2010, but the ecological security of land resources in the region was not optimistic. It was recommended that some policies in order to strengthen the people’s ecological safety awareness, to increase the controlling rate of soil erosion, to balance the process of urbanization and ecological environment construction, to establish a resource-saving society system for social production and consumption, to develop ecological agriculture, and to make full use of the existing resources in order to achieve sustainable economic and social development of Hengyang City on the basis of ecological security.
