- Abstract:
- As one of the first Special Economic Zones in China,Shantou has a large population,with relatively little (arable) land. During the past 30 years,with the rapid economic growth,the ecological environment of Shantou also got through great changes. Using the Socio-economic development characteristics of Shantou as a case,we established land ecological security assessment system which was based on the ‘P-S-R’ conceptual framework mode, with the main data sources of 2001-2008 Shantou Statistical Yearbook, 2001-2008 Shantou Environmental Bulletin, etc. Then 19 indexes according to the concrete features of Shantou City were selected by using principal components analysis method and analytical hierarchy process theory, with referring to related literatures and studying achievements to confirm the weight of indexes, so as to evaluate the safe condition of land ecological security at Shantou from 2001 to 2008. Finally, the result of calculation showed that the integrated value of the land ecological security at Shantou was between adjacent safety and comparative safety statement, yet, with the trend of slight decline, which indicated that it was necessary to take measures to improve Shantou’s land ecological environments. This research showed the current situation of Shantou, which was a reference for land ecological security planning and ecological security management.
