| 摘 要： | On the basis of the ecological footprint (EF) model, this paper studied the ecological security in the Upper Min River Basin ecosystem. The result shows that with 2. 038 2hm^2 per capita ecological capacity (0.422 2hm^2 higher than per capita EF), and 165 825hm^2 ecology surplus, the ecosystem in Upper Min River is generally secure at present. But the arable land is overweighed and omens an ecosecurity crisis. Meanwhile, problems such as low forest coverage rate, severe loss of water and soil, enlargement of aridvalley area, frequent occurrence of mountain hazards and degradation of pastures have been major threats to the eco-security of this region. The calculation result of ten thousand-yuan (RMB) GDP shows that the use of natural resources is extensive, and there will be a rapid increase tendency of EF in the future. In order to maintain the present eco-security, the ways of use natural resources must be improved in the Upper Min River Basin.

The result shows that with 2.038 2 hm2 per capita ecological capacity (0.422 2 hm2 higher than per capita EF), and 165 825 hm2 ecology surplus, the ecosystem in Upper Min River is generally secure at present. But the arable land is overweighed and omens an eco-security crisis. Meanwhile, problems such as low forest coverage rate, severe loss of water and soil, enlargement of arid-valley area, frequent occurrence of mountain hazards and degradation of pastures have been major threats to the eco-security of this region. The calculation result of ten-thousand-yuan (RMB) GDP shows that the use of natural resources is extensive, and there will be a rapid increase tendency of EF in the future. In order to maintain the present eco-security, the ways of use natural resources must be improved in the Upper Min River Basin. |
