| 摘 要： | 热能是生态系统中极其重要的因子.在中小尺度区域的热量资源和热场分布,对绿洲冷岛效应的研究,评价绿洲的稳定性,具有客观直接的证明力.本文利用landsat-7卫星影像来反映地物辐射温度差异这一特点为基础,以新疆奇台绿洲为研究区,应用遥感数据,探索了基于遥感的“冷岛效应”研究方法.结果表明:(1)遥感在探测绿洲“冷岛效应”和干旱区热量空间分部是一种强大而有效的技术手段;(2)在干旱区,绿洲“冷岛效应”明显,而撂荒地和盐碱地含有较高的热能,甚至高于荒漠地带;(3)本方法的使用为研究绿洲的光、热、水、土的空间分布及区域变化,评价绿洲的稳定性提供了一种新的角度,同时对绿洲与荒漠之间的大气物理模型及动力学有一定参考意义.

| Abstract: | The thermal energy is a very important factor in ecosystem.The resource and distribution of thermal energy have objective and direct proof to the analysis the "cold-island effect" and evaluation of the stability of the oasis in middle and small scale areas.This paper makes use of the Landsat-7 satellite image to reflect ground radiates temperature of QiTai oasis in XinJiang.It also develops the RS-method to discover the "cold-island effect"The result enunciation:(1)the RS-method is a very useful and powerful method to detect the "cold-island effect" and the distribution of thermal energy.(2)The "cold-island effect" is obviously in arid and semi-arid area;The Salina and the wasteland even have more thermal energy than the desert.(3)The method in this paper provides a kind of new angle to study the changes of space distributes of light,heat,water,soil,and evaluating the stability of the oasis.And it also has some significance on the model and dynamics of aerophysice between the oasis and the desert. |
