| 摘要: |
| 选取三峡库区2000、2004、2008和2012年4期Landsat-TM数据及相应年限的社会经济人口统计数据为数据源，采用生态足迹模型对库区内的生态消费、生态承载力以及因子结构和时间序列上的变化进行研究；结果表明：2000—2012年间，三峡区内人均生态足迹呈现明显的增长趋势，其中各资源消费性因子总体上都表现为增长的趋势但差异性明显；人均生态承载力表现出持续的下降趋势，并且各生产性土地生态承载力差异性明显，差异性与各生产性土地面积比呈明显的正相关；库区内生态赤字现象严重，随着社会经济的发展，生态赤字程度也逐年加重。 |

| Abstract: |
| Based on the interpretation of the Landsat TM data (with four digital images taken in 2000, 2004, 2008 and 2012, respectively) and the statistical data of the society, economy and population of the corresponding period, this article studies ecological consumption, ecological carrying capacity and the changes of factor structure and time series by the ecological footprint model. The results show that the per capita ecological footprint of the Three Gorges reservoir area presents an obvious growth tendency during the period from 2000 to 2014. Each of the resources consumption factors is all going up,but the diversity is significant. The per capita ecological carrying capacity shows a sustainable downtrend, the diversity of each productive land capacity is obvious and positively correlated with the area of each productive land. Ecological deficit is high and increases year by year with the development of economy. |
