| 摘 要： | 为分析朝阳市土地生态安全情况,采用生态足迹模型对朝阳市2004-2008年的生态足迹和生态承载力进程测算,测算结果:人均生态足迹从2004年的4.344 7 hm2增加到2008年的7.193 8 hm2;人均生态承载力从2004年的1.037 0 hm2增加到2008年的1.060 9 hm2。结果表明:生态足迹的需求量和供给量一直不平衡,始终存在生态赤字现象,区域土地生态系统处于超负荷利用状态,可持续发展的土地利用模式需进一步加强。

| Abstract: | To research the ecological safety of land in Chaoyang,the authors took the ecological footprint analysis to calculate its ecological footprint(EF) and ecological capacity(EC) from 2004 to 2008: the ecological footprint per capita increased from 4.3447hm2 in 2004 to 7.1938 hm2 in 2008;the ecological capacity per capita increased from 1.0370hm2 in 2004 to1.0609 hm2 in 2008.The results showed that ecological footprint demand and supply were uneven;there was the phenomenon of ecological deficit,and the land res... |
