The cultivation of community residents' ecological concept has an important impact on the construction of human ecological civilization. In this paper, the ecological footprint (EF) of community residents' food consumption was calculated and studied by using the theories and methods of biocapacity and EF. The per capita annual EF of the selected three typical communities was high-income community (1.72gha) > ordinary community (1.55gha) > pilot ecological community (1.51gha). As for the components of annual EF of community residents, the carbon footprint accounted for the largest proportion (0.8gha/person), followed by farmland (0.39gha/person) and grassland, and those of construction land, woodland and grassland were relatively small. As for the components of residents' consumption activities in the whole year, food accounted for the largest part of the EF (0.79gha/person), followed by housing (0.49gha/person), and the other components accounted for a relatively small proportion. The per capita carbon footprint of typical communities was high-income community (0.9gha) > ordinary community (0.88gha) > pilot ecological community (0.61gha), which was likely due to the differences in energy consumption-ability of residents in these three communities. Thus it is clear that the consumption-ability of different groups and their preferences for food, clothing, housing and transportation should be considered in the process of community ecological construction. |
