为了揭示张家界烟区植烟土壤特征与海拔高度的关系，为该区烟草的种植布局与合理施肥提供理论依据。采用GPS技术，记录烟区不同海拔高度299个土壤样品的海拔高度和经纬度，利用经典统计学和地统计学方法比较分析了张家界烟区不同海拔高度(<400 m、400~600 m、601~800 m、>800 m)的植烟土壤理化性状差异，综合评价了不同海拔高度植烟土壤肥力状况。结果表明，土壤氮素和有机质、有效硫、有效钼、有效锰含量随海拔高度的升高基本呈上升趋势，而土壤交换性钙、有效铁、有效铜含量随海拔高度的升高基本呈下降趋势，海拔<400 m、>800 m的植烟土壤特征与其他海拔段的土壤差异明显。综合比较各海拔植烟土壤养分含量，以中高海拔(>400 m)更适宜生产优质烟叶。张家界烟区62%的植烟土壤较为适宜，以海拔高度601~800 m的频数分布最高。
為瞭揭示張傢界煙區植煙土壤特徵與海拔高度的關繫，為該區煙草的種植佈跼與閤理施肥提供理論依據。採用GPS技術，記錄煙區不同海拔高度299箇土壤樣品的海拔高度和經緯度，利用經典統計學和地統計學方法比較分析瞭張傢界煙區不同海拔高度(<400 m、400~600 m、601~800 m、>800 m)的植煙土壤理化性狀差異，綜閤評價瞭不同海拔高度植煙土壤肥力狀況。結果錶明，土壤氮素和有機質、有效硫、有效鉬、有效錳含量隨海拔高度的升高基本呈上升趨勢，而土壤交換性鈣、有效鐵、有效銅含量隨海拔高度的升高基本呈下降趨勢，海拔<400 m、>800 m的植煙土壤特徵與其他海拔段的土壤差異明顯。綜閤比較各海拔植煙土壤養分含量，以中高海拔(>400 m)更適宜生產優質煙葉。張傢界煙區62%的植煙土壤較為適宜，以海拔高度601~800 m的頻數分佈最高。

This paper was aim to reveal the relationship between soil characteristics and the altitude in Zhangjiajie tobacco-growing area, and to provide theory evidence for tobacco planting programming and rational fertilization. 299 of soil samples were collected, and the elevation were recorded by using GPS technology. The difference of soil physical-chemical properties at different altitudes (below 400 m, between 400-600 m, between 601-800 m, above 800 m) was compared, and the status of soil fertility was evaluated by using descriptive analysis characteristics and spatial interpolation characteristics methods. The results showed that, basically, the content of soil nitrogen, organic matter, available sulfur, available Mo, available Mn were increased with the increasing of elevation, while the content of soil exchangeable Ca, available Fe, available Cu were decreased with the decreasing of elevation. The attitude below 400 m and above 800 m had obvious difference with other attitudes. By comparing the content of soil nutrient in different attitude, the soil in high altitude was preferably for high quality and characteristic tobacco production. In conclusion, 62%soil samples were suitable and the attitude 601-800 m had the highest frequency distribution in suitable soil of Zhangjiajie tobacco-growing area.
