吉林省镇赉县位于我国北方农牧交错带，作为一个国家商品粮基地，农业发展的比重大。为了探讨镇赉县生态环境现状和资源消耗特点以及农牧交错带在承担外来资源压力转移方面的作用，应用生态足迹法对镇赉县2010年生物资源生产数据和能源消费数据进行了分析，结果表明镇赉县农牧业发展在资源利用中占主要地位，农牧业生产中大部分产品用于对外销售，因此该地区承担了巨大的外来资源压力转移，已经出现生态赤字。进一步分析还发现，为推动农业发展，当地通过扩大耕地面积来解决粮食产量低、无复种的问题，因此占用其他土地类型，这些活动过度干扰了生态环境，加剧了镇赉县生态环境的恶化。

Zhenlai County of Jilin Province is located in the farming-pastoral ecotone in northern China. As a commodity grain base, agricultural development is an important activity in this area. In order to investigate the current ecological and environmental conditions, the feature of resource consumption, and the pressure shift of external resources in the farming-pastoral ecotone in the study area, the ecological footprint method was used to analyze the biological resource production and energy consumption data in 2010 of Zhenlai County. The results showed that agriculture and animal husbandry developments are the primary resource consumers in Zhenlai County. Most of the farming and pasturing products were sold to other places; therefore this area sustained a huge pressure shift of external resources and the ecological deficit occurred in Zhenlai Country. A further analysis indicated that the increasing of agricultural acreage to solve the problems of low yield and single cropping to promote the agricultural production can occupy other land use types, which can disturb the ecological environment significantly and aggravate the degradation of ecological environment in Zhenlai
