摘　　要：以吐尔根杏花沟实地路线调查信息、WorldView-3卫星遥感影像和SRTM DEM数字高程模型为数据材料,采用遥感面向对象提取与数字地形分析方法,统计新疆野杏(Prunus armeniaca)面积和覆盖率,研究野杏对不同坡向的适应性。结果表明:(1)野杏面积阳坡多于阴坡,而野杏覆盖率阴坡高于阳坡。(2)野杏覆盖率在不同坡向上都有随海拔上升先递增、后递减的垂直地带性。(3)野杏覆盖率在不同坡向上都随坡度增陡而升高。沟谷西南部、野杏面积占优的阳坡和覆盖率占优的阴坡、中山带下部中段约1100~1500 m的海拔梯度、部分较陡坡面等适应野杏生存的区域,可因地制宜地开展封育更新、恢复重建、引种栽培等实验与措施。Taking field route survey information,WorldView-3 satellite remote sensing imagery and SRTM DEM as data materials,using remote sensing object-oriented extraction and digital terrain analysis methods,a quantitative study on the spatial distribution of Prunus armeniaca area and coverage was carried out to understand the adaptability of P.armeniaca to different aspects in Turgen Apricot Blossom Valley.It was found that:(1)the area of P.armeniaca was more on the sunny slope than on the shady slope,while the coverage rate of P.armeniaca was lower on the sunny slope than on the shady slope.(2)The coverage rate of P.armeniaca has typical vertical zonality in different slope directions,first increasing and then decreasing with the increase of altitude.(3)The coverage of P.armeniaca increased with the increase of slope gradient in different slope directions.In the suitable areas for P.armeniaca survival,such as the southwest of the valley,the sunny slope with the dominant area of P.armeniaca and the shady slope with the dominant coverage rate,the altitude gradient of about 1100-1500 m in the lower middle section of the middle mountain belt,and some steep slopes,we can carry out experiments and measures such as enclosure,regeneration,restoration,reconstruction,introduction and cultivation according to local conditions.
