Abstract Research purposes：Aiming at the influence of railway construction on ecological environment, this paper calculates and analyzes the sustainable capacity in ecology of the Qiandongnan Miao & Dong Autonomous Prefecture in 2006 with ecological trace model and discusses the methods and measures for construction of "green railway" in the southwest mountainous area where is a ecological sensitive area for the purposes of providing the reference method for coordinating railway construction with the environment protection.
Research conclusions：(1) The ecological trace and ecological capacity per capita of the Qiandongnan Miao & Dong Autonomous Prefecture in 2006 were 1.322 62 hm2 and 0.756 66 hm2 separately, and the ecological deficit per capita was 0.566 96 hm2, so the social and economic developments of the prefecture were unsustainable. (2) In order to construct the "green railway" in the Qiandongnan Miao & Dong Autonomous Prefecture and coordinate the railway construction with the environment protection, it is necessary to protect the forestry resource and water resource and make reasonable use of land resource.
