摘要:

阿尔泰山圆叶桦由于生长周期短、对气候变化反应灵敏,具有典型的指示意义.以长时间序列遥感数据为基础,借助GIS技术和分形插值方法,研究近24 a来阿尔泰山圆叶桦的空间分布对温度变化的响应,结果表明:近24 a来阿尔泰山气温上升速率为0.18℃·(10a)-1,圆叶桦面积增速达7.28%,圆叶桦随随温度上升呈显著增长,且温度上升速率越大,圆叶桦面积增长越快;圆叶桦分布的平均海拔随温度升高呈上升趋势,温度上升不仅促进了圆叶桦面积的扩大,还抬高了圆叶桦分布的平均海拔,且温度变化对海拔较高区域的植被生长影响力较大;各坡向圆叶桦面积随温度的上升均有所增加,温度上升对阳坡圆叶桦影响显著,对阴坡圆叶桦影响微弱.

Abstract:

The spatial distribution of the response to temperature change of Altay Betula rotundifolia were studied by used GIS technology and fractal interpolation method based on long series of remote sensing data. The results showed that:(1) In the last 24 years, temperature in the Altay Mountains has risen with the rate of 0.18℃ every ten years, Betula rotundifolia cover area has grown 7.28%, Betula rotundifolia has significantly grown with temperature, and the faster the temperature rising, the faster the Betula rotundifolia cover area growing; (2) Along with temperature rising, the average elevation of Betula rotundifolia distribution has risen, temperature rising not only expands Betula rotundifolia cover area, but also rises average altitude of Betula rotundifolia distribution and temperature varying at higher elevation has more effect on vegetation growing; (3) With temperature increasing, Betula rotundifolia cover area has increased at all exposures, especially, on the sunny sides.

Key words: Altay Mountains, Betula rotundifolia, spatial distribution, temperature change
