摘要
以广西铜匠村的生态足迹模型为例探讨了生态足迹法在村庄层面应用的适用性。结论表明,生态足迹模型在衡量村庄生态状况时有着更为可靠的准确性,但也存在4种因素限制其精确性,数据获取较难、外出务工者较多、生态效益较大以及土地"兼职"较广。针对外出务工者的影响,提出了其时间折算法,对于其他缺陷则阐明了在模型完善方面的研究现状。
This paper takes the ecological footprint model of Tongjiang village in Guangxi as an example,discusses the applying applicability of ecological footprint model in the village-level.Conclusions show that,the ecological footprint model has a more reliable accuracy when measuring the ecological status in villages,but there are four factors that restrict the accuracy including the larger difficulties of date acquisition,the larger number of migrant workers,the larger benefit of eco-efficiency and the larger breadth of overlapping usage in land.For the impact of migrant workers,the paper innovatively proposes the method of the conversion in time,and for others specific deficiencies,it illustrates the current researching situation of model improving.
